Med Student Dies of Measles a Completely Preventable Disease




Until recently health authorities thought they had almost eliminated measles from Europe. But now the potentially deadly illness is on the rise because of a dramatic fall in vaccination rates. Worst hit is Ukraine, now suffering one of the worst measles epidemics in the world, with more than 100,000 cases since 2017.
On an autumn day in 2017, Oksana Butenko waved goodbye to her teenage son Serhiy as he set off for university to study to become a doctor.
Eighteen months later, in February this year, she brought his body back to her small village in western Ukraine in a coffin.
The young man who wanted to devote his life to curing people of diseases had himself died at age 18, suddenly, of an illness health authorities say is completely preventable - measles, a disease they thought, a few years ago, they had almost eradicated in Europe.

"He was a brilliant boy," Oksana says, standing outside the little silver-domed village church where her son's funeral was held. "He was the most precious thing I ever had. It was his dream to become a medic, that's what he lived for. 
"I don't know why it happened. I remember my childhood, everyone got measles, but they all recovered." 
Measles is a highly contagious disease that most people get over after a couple of weeks of high temperature, and an unpleasant skin rash. But in a few cases - one or two in a thousand - it leads on to fatal complications, most commonly pneumonia.
Serhiy died of pneumonia brought on by measles after several days in intensive care, infection eating away at his lungs, unable to breathe without artificial ventilation.
He was one of 39 people to have died of measles in Ukraine since the current outbreak began in 2017. 
Measles has been surging across Europe, with the number of new cases tripling last year to 82,596. The majority of those were in Ukraine, with 53,218 catching the disease.

"We have this perfect storm of what happened over the last 40 years and it's culminated in the problem that we have now," says the country's acting health minister, Ulana Suprun. She's talking about the dramatic decline in the proportion of people who are protected against measles by vaccination.
Until about 2001, she says, Ukraine imported a strain of vaccine from Russia that the World Health Organisation (WHO) later declared to be ineffective. As a result, "about 44% of the measles cases in Ukraine are adults - adults who thought that they had been vaccinated, but the vaccine was not useful". 
Then there was a problem with the cold chain - keeping the vaccine refrigerated so that it remains effective. Amid the economic collapse that followed the break-up of the Soviet Union in 1991, with poorly-equipped hospitals and unreliable energy supplies, the vaccine wasn't always kept at the correct temperature. 
But an even greater problem was psychological. As the years went on, more and more people refused vaccination for themselves or their children.
"It's a question of trust," says Oles Pohranychny, headmaster of a private primary school in the western city of Lviv. Two years into the epidemic, only half his pupils are vaccinated against measles. 
"Vaccine is something that I take, and believe that it will protect me against something. Now our school has the children of parents born in the 1990s when no-one believed anything. Not one another, not medicine, not the state.
"In the whole former Soviet Union, it was a period of transition from a paternalistic society, to a society where you are responsible for yourself - but you don't know how to be responsible for yourself. Everyone around was lying - that's what people thought in the '90s. You had to be like a clenched fist, and trust no-one. Otherwise, you were a loser. Trust was for losers." 
Dr Suprun, the acting Health Minister, blames the media and politicians for fanning the anti-vaccination mood, particularly after a widely-publicized incident in 2008 when a schoolboy called Anton Tishchenko died shortly after being immunized against measles - through a medical report later showed that his death was unconnected to the vaccine. 
In the wake of that tragedy, vaccination rates fell so drastically that by 2016 only 31% of the population were covered by MMR, the main vaccine against measles, mumps and rubella - the lowest level of vaccination in the world, even lower than in Africa, as Dr Suprun put it.
The WHO recommends 95% of children should be immunized with the MMR vaccine to achieve the herd immunity level at which all children - vaccinated and unvaccinated - are protected from measles, mumps, and rubella.

Dr Suprun says that even now she is fighting a tide of misinformation. "We have politicians trying to get votes saying that you don't need to be vaccinated, it's all a big plot by Western governments to take over the minds of our children, that vaccine is a big plot by pharmaceutical companies to come in and make a lot of money off of Ukraine. Unfortunately, even with 39 deaths, it's difficult to convince people that this is a real problem."
The death of Serhiy Butenko, however, did jolt his fellow students at Vinnitsa Medical University, in central Ukraine.
"There was a feeling of emptiness," says Oleh Yefymenko, head of the student council. "A lot of people knew him, really his story touched everyone."
Medical records show that Serhiy had been vaccinated, at the ages of one and six, as recommended by the health authorities. But it wasn't enough to protect him, because he caught the measles virus just after being taken ill with another viral disease - mononucleosis, or glandular fever.
"This mononucleosis weakened his immune system so that it could not fight properly against the measles virus," says Dr Alexandra Popovich, who oversaw Serhiy's treatment in his last days.
It's possible that he would have been better protected if he had had a recent booster jab of vaccine.
But the more important lesson to take from the tragedy, says Dr Popovich, is that Serhiy would not have died if he hadn't been exposed to measles in the first place if the level of herd immunity in the population had been high enough. 
After Serhiy's death, many of his fellow students rushed to get vaccinated, according to student leader Oleg Yeminenko.

But how come medical students, future doctors, hadn't thought of that long before? By that time the measles outbreak had been raging for nearly two years. 
The University authorities told the BBC they conducted a major campaign last year to encourage students to get jabbed and achieved a vaccination rate of more than 98%.
They said students are taught about vaccination "from the point of view of evidence-based medicine, studying immunology, statistical data, contra-indications, and consequences."
But Kateryna Bulavinova, of the United Nations children's agency UNICEF, which has been helping the Ukrainian government in the fight against measles, said Serhiy Butenko's death showed that university deans are not doing enough, in general, to protect students.
"In my personal opinion this is a horrifying situation because it was preventable," she said. "For me, it's a big mystery, because it's the third year of the outbreak in Ukraine with huge figures of those who contracted measles. But still, the deans of all medical universities didn't take their position about protecting students."
"The biggest issue is with health care workers themselves. We have got more and more young doctors who have no idea about immunization, or doubt immunization, or are against immunization."
The health minister Ulana Suprun also believes doctors themselves are the main spreaders of doubt about vaccines.

She says that some student doctors are taught that vaccinations are not necessary. The rationale is the belief that it is better for a child to contract the disease because then they will have immunity for the rest of their lives. "When you have academics at that level teaching new doctors that they don't need to vaccinate the children, it really does confuse the issue," Dr Suprun says.
The government's chief pediatric immunologist, Dr Fedir Lapiy, says "We have professors who believe that vaccination against measles during the influenza season, October to May, for example, is a dangerous procedure because it will cause immunosuppression. That's a myth, false information. It's dangerous for the country."
Dr Suprun says misinformation by health workers and medical academics cannot be stopped because universities are independent and there is currently no means to withdraw professional qualifications. But a system to license physicians that will make that possible is now being introduced.

She says many of the problems that led to the epidemic are now being overcome. Vaccines are procured by Unicef, which has assisted the government in visiting hospitals and clinics to ensure the cold chain is maintained.
"The vaccines that have been given in the last year or two years, we know have worked," she says. "We've vaccinated last year over 900,000 people and we had zero deaths or serious complications from the vaccine."
Mobile vaccination brigades have toured the regions worst hit by the epidemic to immunise children who missed getting the jab. Free vaccination is also now available to all adults.
Last year, 90% of one- and six-year-olds were vaccinated against measles. But that still leaves a huge backlog of children, and adults, who failed to be vaccinated at the right time in earlier years. 
And Unicef estimates that as many as 30% of vaccination certificates may be falsified. 
"When parents are told that it's required to vaccinate their children to have them come to schools, they then go to physicians and unfortunately buy vaccine certificates," Dr Suprun says. 
In Lviv region, the worst-hit, she says, "when we came into the (regional) department of health and asked them how many children will need to be vaccinated, they told us by their records it's 22,000. But when we went to the schools, and we verified which records were accurate, we found that it was 50,000 children that needed to be vaccinated, because 28,000 had fake vaccine certificates."

By law, Ukrainian children have to be vaccinated against certain diseases, including measles, in order to attend state schools. But the law is not always observed, and it is also contested by some parents including Veronika Sidorenko, founder of a movement called "Vaccination - Free Choice."
Her three children are unvaccinated. "When I compared the risk of getting the disease, against which we vaccinate, and the risk of the consequences of vaccination, I decided not to vaccinate," she says.
According to the WHO, the risk of suffering a severe allergic reaction to the measles virus is one in a million. But Veronika mistrusts WHO statistics. She thinks the campaign for universal vaccination is driven partly by lobbying by the pharmaceutical industry. 
"If we had large scale research - let's say 1,000 non-vaccinated children and 1,000 vaccinated ones, and we could trace their life through 50 years - we could actually assert that [vaccination prevents measles outbreaks]. But we don't have that and no-one is going to do it, so I believe we can't say for sure."
When challenged that her choices are putting other children in danger, she says she doesn't believe in herd immunity. 
In the meantime, the epidemic in Ukraine is continuing to gain pace, with almost as many new cases in the last six months as in the whole of last year. The 39th victim of measles complications died this month. 
"This is the era of iPhones and all kinds of high technologies," says Unicef's Kateryna Bulavinova. 
"To have this high a number of people dying of completely preventable disease are horrible."

On This 4th of July Puerto Ricans in The Island find a Hidden Bacteria Has Been Spiked by Maria



 This page was published yesterday on CNN and was written by John D. Sutter, CNN Investigates, and Omaya Sosa Pascual, Center for Investigative Journalism

Cayey, Puerto Rico (CNN)Puerto Rico's own records list so many cases of the bacterial disease leptospirosis that officials should have declared an "epidemic" or an "outbreak" after Hurricane Maria instead of denying that one occurred, according to seven medical experts who reviewed previously unreleased data for CNN and the Centro de Periodismo Investigativo (CPI). 
A Puerto Rico mortality database -- which CNN and CPI sued the island's Demographic Registry to obtain -- lists 26 deaths in the six months after Hurricane Maria that were labeled by clinicians as "caused" by leptospirosis, a bacterial illness known to spread through water and soil, especially in the aftermath of storms. That's more than twice the number of deaths as were listed in Puerto Rico the previous year, according to an analysis of federal records. 
"Twenty-six deaths attributed to leptospirosis -- that's extraordinary," said Dr. Joseph Vinetz, a professor of medicine at the University of California San Diego and an expert on the disease, who reviewed the data. "There's no other way of putting it ... The numbers are huge." 
Puerto Rico's Health Department attributed only four leptospirosis deaths to Hurricane Maria until June 22, when it added two more after CNN and CPI asked about the 26 deaths. Officials maintained that the timing was related to laboratory tests and not questions from reporters. 
Laboratory tests typically take weeks, not months, experts said. 
The two additional deaths have not been added to the official Hurricane Maria death toll of 64. A spokeswoman for the Department of Public Safety, which determines the death toll for the storm, said the government will not adjust the number until the researchers it hired at George Washington University complete a review of the death toll from the hurricane. 
The Hurricane Maria death toll has come under intense scrutiny following investigations by CNNCPI and others. In May a study in the New England Journal of Medicine estimated based on interviews that 793 to 8,498 people died for reasons related to Hurricane Maria, with many of those deaths being attributed to the lack of services, like electricity, in the storm's aftermath.
The mortality database does not indicate whether the cases were confirmed in laboratory tests as related to leptospirosis. It only shows whether "leptospirosis" was written on a death certificate. But CNN and CPI investigated two suspected leptospirosis deaths that were uncounted in the official Hurricane Maria death toll and appeared, based on interviews with families, neighbors and doctors to be related to the storm. Both men were relief workers or volunteers who spent considerable time in floodwaters, where the disease is known to spread. 
    One of the men, Daniel L. Vick, a 31-year-old father from Cayey, tested positive for leptospirosis at a local lab, according to his doctor. His medical records, provided by his family, show he was hospitalized with "fever/chills," "nausea/vomiting" and "diarrhea," which doctors say is consistent with the disease. Before his third and final hospitalization, family members and neighbors said, he was seen coming out of his house with jaundiced, yellowed skin -- another sign of leptospirosis. 
    His mother doesn't understand why his death is uncounted. 
    "Maybe the government thought that the more people (that) died the worse it would look -- that it meant they did a bad job responding to this tragedy," Margarita Rodriguez said. "It's incomprehensible. It seems like they don't care. The only thing they care about is their image."
    Leptospirosis is very rarely fatal and can be treated with common antibiotics. It is carried mostly in the urine of rats and other animals. It can be ingested in drinking water or absorbed through cuts in the skin. Neither of the men whose deaths CNN and CPI investigated were given gloves, boots or prophylactic antibiotics, according to their families. Those simple measures can help prevent leptospirosis illnesses among people working in floodwaters, experts said.
    In general, epidemiologists said that deaths occurring closer to the September 20, 2017 hurricane were more likely to be linked to the storm than those occurring in 2018. The 26 deaths labeled "leptospirosis" in Puerto Rico's data occurred between September 24, 2017 and March 6, 2018. The majority of those deaths -- 21 -- happened before December 31.
    For comparison, there were 11 suspected leptospirosis deaths in Puerto Rico the previous year, according to Centers for Disease Control and Prevention (CDC) mortality data analyzed for CNN and CPI by an independent demographer.
    Puerto Rican officials say they only are counting leptospirosis deaths as hurricane related if the illnesses were confirmed by CDC tests and if the deaths occurred between September 20, the day of the storm, and October 20. 
    Daniel Vick's mother, Margarita Rodriguez, holds a photo of her son, whose death was labeled "leptospirosis" in a database obtained by CNN and CPI.
      Vick's death occurred on October 19, one day before that cutoff. It's unclear whether his death was analyzed by CDC tests because officials declined to comment on specific cases.
      Vinetz, from UCSD, called the one-month timeframe indefensible because it can take three weeks for leptospirosis symptoms to show up after infection; and because hurricane clean-up -- and the potential for exposure to leptospirosis that goes with it -- continued for weeks. 
      "It's not justified," he said. "It's probably too restrictive and it underestimates the numbers ... I think it's more probable than not it's a political decision. It's not justified by the medical science."
      Asked by CNN and CPI why so many more leptospirosis-labeled deaths appear in Puerto Rico's mortality records than have been publicly acknowledged as storm-related, Dr. Carmen Deseda, Puerto Rico's state epidemiologist said, "a lot of times the physicians don't have access to the full records, and the laboratories may still be pending."
      Authorities are investigating the 26 cases shown in death records, Deseda said.

      'Epidemic'

      Several data sources suggest an "epidemic" or an "outbreak" of leptospirosis occurred in the aftermath of Hurricane Maria -- but Puerto Rican officials won't call it that. 
      On Friday, the Centers for Disease Control and Prevention (CDC) released its own statistics on leptospirosis deaths on the Caribbean island under the US Freedom of Information Act. The internal CDC document lists 17 "confirmed and probable" deaths after the hurricane in which laboratory tests show leptospirosis was a factor -- plus 25 additional "suspected" leptospirosis deaths that were in need of further lab confirmation.  
        In addition to the deaths, there's also evidence leptospirosis illnesses increased. 
        The Puerto Rico Department of Health told CNN and CPI there were 57 laboratory-confirmed cases of leptospirosis illnesses in 2017 -- 54 of them after Hurricane Maria, which hit September 20. That's a three- and four-fold increase in confirmed illnesses over the previous two years, according to the figures provided. Comparing months, the spike is sharper still -- with 31 confirmed illnesses in October 2017 compared to four the year before; and 16 illnesses in November 2017, sixteen times more than the single confirmed illness in November 2016. 
        There is no internationally established threshold for declaring a leptospirosis "outbreak" or "epidemic," according to epidemiologists, many of whom use those terms almost interchangeably. The CDC defines an epidemic generally as "an increase, often sudden, in the number of cases of a disease above what is normally expected in that population in that area." Outbreaks often refer to "a more limited geographic area," the CDC says.
        Puerto Rican health officials have cited conflicting thresholds they say are needed to declare a leptospirosis epidemic. In November, Puerto Rico's secretary of health, Dr. Rafael Rodríguez Mercado, told a local radio reporter "200 cases per week" were needed to make that declaration. Dr. Cruz María Nazario Delgado, a professor and epidemiologist at the University of Puerto Rico Medical Sciences Campus, told CNN and CPI that metric is "a bunch of nonsense." (On Monday, Rodríguez Mercado told CNN and CPI that he misspoke in that interview.)
        In an interview with CNN and CPI on June 25, Deseda, Puerto Rico's state epidemiologist, said that officials would need to see a "twofold" increase in cases to declare an epidemic. 
        Then on Monday, after CNN and CPI questioned these inconsistencies, Deseda released a statement through a spokesman paraphrasing the CDC definition of an outbreak or epidemic -- and adding that it is "not appropriate" to compare the number of illnesses after the storm to previous years. That's because officials were more-actively looking for leptospirosis illnesses after Hurricane Maria and were doing so using different diagnostic tests, she said.
          Three experts who reviewed data for CNN and CPI said it was clear from records that the government's previously stated "twofold" threshold for an epidemic had been met -- if not far exceeded -- based on the fact that lab-confirmed illnesses more than doubled after Hurricane Maria.
          Another way to assess the Health Department data, however, would be to look at both "confirmed" and "probable" leptospirosis illnesses, experts said. Both are at least partially confirmed by laboratory tests. Looking at the numbers that way shows at least a "twofold" increase when comparing October or November 2016 to 2017, but slightly less than two times the number of illnesses -- 1.6 times -- when you compare all of 2016 to the following year. 
          Deseda told CNN and CPI on June 25 that the Puerto Rico Department of Health did not have access to its own laboratory tests in the chaotic aftermath of the high-powered storm, and that adequate baseline data needed to declare an epidemic was not available.
          "Leptospirosis is one of those diseases where it's very hard to declare an epidemic," Deseda said, "because, at that time, there was no testing we could do to validate or confirm the cases ... It took about three or four weeks to send samples (to the CDC) because of the heavy impact of the hurricane -- and the devastating impact on our communications and power supply.
          "There was no way our laboratory was ready to put samples together. How could we declare an epidemic if we didn't have that number (of confirmed cases) at that time?"
          Officials responded to the illnesses urgently, she said, warning the public about the dangers of floodwaters, ensuring hospitals were supplied with antibiotics and telling physicians to treat signs of leptospirosis as if the disease had occurred, even if lab tests weren't quickly available. 
          On October 22, Public Affairs Secretary Ramon Rosario Cortes told reporters that suspected cases of leptospirosis were "neither an epidemic nor a confirmed outbreak." "But obviously," he added, "we are making all the announcements as though it were a health emergency."

          'The evidence is just incontrovertible'

          Seven experts -- five epidemiologists and two medical doctors who specialize in the related diseases -- told CNN and CPI that Puerto Rico's mortality database and its own figures on confirmed leptospirosis illnesses suggest that an "epidemic" or an "outbreak" occurred.
          The labels "epidemic" and "outbreak" are important, according to public health experts, because they can trigger increased surveillance for the disease and more robust efforts to prevent infection. They also help the public process the severity of the situation and take warnings seriously, which can lead to illness prevention and better treatment, experts said. 
          "In a situation like this, after a natural disaster, the important thing is to take control of the situation -- not to hide the situation," said Nazario, the professor and epidemiologist at the University of Puerto Rico Medical Sciences Campus. Officials, she said, had reason to believe there was a significant number of cases of leptospirosis after Hurricane Maria.
          The leptospirosis cases should have been classified as an epidemic, Nazario said, adding that it is surprising that officials continue to be in "denial" that one occurred last year. Puerto Rican health officials had enough information to declare an epidemic even before CDC tests became available to them, she said.
          "The Department of Health was not doing its job", she said. 
          Luis Diaz Garcia keeps his brother's ashes in a box on his kitchen counter. He believes Ramon Diaz Garcia's death is related to Hurricane Maria.
          The data shows an "unrecognized epidemic," said Dr. Albert Icksang Ko, a professor and chair of the Department of Epidemiology of Microbial Diseases at the Yale School of Public Health.
          "The outbreak of leptospirosis that occurred after Hurricane Maria and associated deaths were predictable," he said. "Disasters, whether they occur in Puerto Rico or elsewhere throughout the world, are triggers or drivers of leptospirosis ... It really emphasizes the challenges we have in addressing leptospirosis public health issues in Puerto Rico," he added. "This information should have been public and I'm surprised you had to sue in order to get this information." 
          "The real question is 'why?'" said Dr. Lemuel Martinez, an infectious disease specialist in Manati, Puerto Rico. "If they had the data, why would they not declare [an epidemic] at the time? ... This is not a matter of opinion. The data is there. Why would they withhold it?"
          The numbers are stunning, said Vinetz, the UCSD professor. "The evidence is just incontrovertible that there's something going on -- something important going on," he said. "It's piffle not to call this an outbreak or an epidemic."
          Several experts stressed that leptospirosis is under-researched. Physicians often miss or mis-diagnose the disease, which has symptoms that mirror other diseases like flu and dengue, including "fever, headache, chills, muscle aches, vomiting/diarrhea, cough, conjunctival suffusion, jaundice, and sometimes a rash," the CDC says. Untreated, according to the CDC, a person "could develop kidney damage, meningitis, liver failure, and respiratory distress."
          The other experts saying an epidemic or outbreak should have been declared were: Jonas Brant, a professor and epidemiologist at the University of Brasilia; Dr. Melissa Marzán Rodríguez, an epidemiologist and professor of infectious diseases at Ponce Health Sciences University, in Puerto Rico; and Claudia Muñoz-Zanzi, an epidemiologist at the University of Minnesota School of Public Health, who said this is the "definition" of an outbreak.
          "We need to increase awareness about leptospirosis and about these outbreaks -- and (about) the need to do more research in order to detect these outbreaks as early as possible" and to say how best to respond, said Muñoz-Zanzi. "Without [public officials] declaring outbreaks, we cannot do that because we don't have the data we need to establish those recommendations."
          Worldwide, the disease is estimated to contribute to more than 1 million illnesses and nearly 60,000 deaths per year, the CDC says. 
          Two additional experts said an outbreak could have been declared -- but would not go so far as to say that it should have been declared by Puerto Rican authorities without better baseline data and without understanding exactly what officials did and did not know at the time. 
          Dr. Brenda Rivera García, a former state epidemiologist in Puerto Rico, said there is clear baseline data available for officials to judge whether an epidemic occurred. In retrospect, she said, there was a significant increase in cases in a short timeframe -- but she's unsure if the Health Department had all the necessary information at the time to declare an epidemic. 

          'Almost non-existent'

          CNN and CPI investigated a total of four deaths labeled in government data as having been related to leptospirosis that were uncounted as part of the Hurricane Maria death toll. 
          After interviewing relatives and neighbors, consulting with experts on the disease and, in one case, reviewing hospital records, at least two of these uncounted deaths appeared to be related to Hurricane Maria, based on CDC-established criteria for disaster deaths.
          At least one case appeared to be unrelated to the storm.
          Jose A. Sanchez Vazquez, 58 was hospitalized before Hurricane Maria hit, according to Ana Sanchez, his sister. He died four days after Hurricane Maria, records show. Because he got sick before Hurricane Maria made landfall, Ana Sanchez does not consider his death storm-related.
          In Bayamon, a suburb of San Juan, Puerto Rico's capital, Ricardo A. Cotto Rodriguez, 48, who was known in his neighborhood for his humor and for being the fanatic water boy for the Vaqueros, the local basketball team, died on November 17, records show. Relatives told CNN Cotto was essentially bedridden after the storm and that his bed sores became infected.
          He was hospitalized after he fell and became stuck in the shower, they said, when there was no electricity in the area. Gilberto Rodriguez Quiñones, his cousin, said his death appears to have been related to Hurricane Maria because of that fall, which he said occurred in darkness, without power. But it was unclear how he may have contracted a waterborne illness.
          The government database lists "leptospirosis," "chronic ulcer of skin" and "obesity" among the contributors to Cotto's death. His death certificate says leptospirosis "possibly" contributed.
          Ana Sanchez says her brother's death, labeled "leptospirosis" in government records, is not related to Hurricane Maria.
          In two other cases, however, family members and neighbors of the deceased described circumstances that medical professionals say are consistent with leptospirosis.
          Both men were working in relief efforts after the storm, putting them in contact with flood waters that, according to experts, would increase their chances of infection.
          And neither, according to family members, was given gloves, boots or prophylactic antibiotics, which public health experts say can be used to prevent leptospirosis infection.
          Deseda, the state epidemiologist, said relief workers were given preventative help. Officials adequately publicized the risks of leptospirosis, she said, and antibiotics were available at hospitals. When pressed, she did not state clearly whether drugs were used preventatively.
          She defended Puerto Rico's efforts to warn the public about the disease, saying she appeared on television and the radio warning people to stay away from possibly contaminated waters and trash -- places where urine from rats and other animals may have been found.
          Martinez, the doctor in Manati, Puerto Rico, said communications from the Health Department about leptospirosis were "almost non-existent, at best." They largely focused, he said, on denying an outbreak was occurring and telling physicians to treat patients regardless of lab tests. 

          'It shocked me'

          In Toa Baja, Luis Diaz Garcia, 55, told CNN and CPI that his younger brother, Ramon Diaz Garcia, 52, was generally healthy before the storm. He suddenly became sick and then disappeared after spending weeks volunteering with cleanup efforts, Luis Diaz said. The family spent a month in agony, not knowing what had happened before a relative contacted the Bureau of Forensic Sciences in San Juan. The database shows Ramon Diaz's death on October 26 was reviewed by the Bureau of Forensic Sciences, which did not conduct an autopsy.
          "Leptospirosis" is listed among the contributors to his death in the records.
          "The pathologists told us that he had a strange color, that he looked yellowish," Luis Diaz said. "They asked if he had hepatitis, and we said, 'No, he was healthy.'"
          Martinez, the infectious disease specialist, said yellow skin is a clear sign of leptospirosis, especially when it's accompanied by acute fever and occurs after a storm. "If someone turns yellow after a hurricane, that's leptospirosis unless proven otherwise," he said.
          Puerto Rico's Bureau of Forensic Sciences is authorized to classify deaths as hurricane-related. Yet Ramon Diaz's name does not appear on Puerto Rico's list of 64 hurricane victims.
          Ramon Diaz Garcia's room in Toa Baja, Puerto Rico, is hauntingly empty.
          Ramon Diaz did not have identification on him when he went to the hospital, his brother said. Forensics workers told Luis Diaz that if the family hadn't contacted them his body would have been cremated in a matter of days and would have remained unidentified, he told CNN and CPI.
          "It shocked me," Luis Diaz said.
          "He was cool with everyone. He would help anyone who needed it," Luis Diaz said of his brother, one of 13 siblings. "That guy would put you to sleep talking and talking -- telling jokes!"
          Ramon Diaz was living with him at the time of the storm, Luis Diaz said. Ramon Diaz's room is now hauntingly empty. The blades of a fan are motionless on the floor. A clock that hasn't worked for years hangs on the wall, stuck just after 4 p.m. A mattress is crumpled in the corner.
          Luis Diaz struggles to understand why his brother remains uncounted.
          "I don't know what to tell you," he said, appearing choked up by the question.
          He keeps his brother's ashes in a box on the kitchen counter.

          'He sacrificed himself'

          Daniel L. Vick, the young father in Cayey, also is uncounted.
          The 31-year-old, who loved the beach, karaoke nights and watching his 7-year-old dance salsa, spent his days after Hurricane Maria wading through floodwaters to help neighbors as an employee of the city of Cayey, relatives said. His death on October 19, which Puerto Rico mortality records label as "caused" by "leptospirosis," is not counted as a hurricane death.
          The physician who certified his death, Dr. Julio Garcia at Centro Médico Menonita de Cayey, told CNN and CPI that a local laboratory test indicated he had leptospirosis. 
          Before his third and final hospitalization, family members and neighbors said, he was seen coming out of his house with jaundiced, yellowed skin -- another sign.
          Margarita Rodriguez said her son was in "perfect health" before the storm.
          Officials declined to comment on the deaths of Vick or Diaz beyond saying that they had not been officially classified as related to Hurricane Maria. One of the two cases -- either Vick or Diaz -- was confirmed by laboratory tests as having been caused by leptospirosis, said Deseda. She refused to say which of the two it was, however, adding that the lab-confirmed leptospirosis death was not counted as hurricane-related because of the date it occurred. Rodriguez said she pleaded with her son to stay alive. 
          "You have to be strong," she recalls telling her son in the hospital. "We need you here -- for your daughter, for your wife, and to keep helping your community. We need you here."
          "You could see tears running down his face" as medical professionals intubated him, pushing a tube down his airway so he could continue to breathe, she said in an interview. "You could tell by looking in his eyes that he didn't want to close his eyes -- to let himself go."
          "He sacrificed himself," she added. "He gave everything ... He should be considered a hero."
          "I just want him to be remembered," she said.
          Margarita Rodriguez will remember her son as a shy, kind, caring and thoughtful man, a man who loved his family and loved his work, who rarely stepped into the spotlight but whose worth was measured in all he quietly did to help others, especially after Maria.
          His widow, Ingrid Nieves García, 29, left a pair of his shoes at an impromptu public memorial for victims of Hurricane Maria at the Puerto Rican capitol building in San Juan.
          In early June, mourners placed thousands of empty shoes near the steps to represent uncounted victims.
          Leaving Vick's shoes there was important "because I never had the space or moment to say goodbye in his funeral. It was just not in me to do that back then," she told CNN and CPI. "I believe the moment I brought his shoes (to the memorial), which were the last thing I had left from him, it helped me to let go, to say goodbye. It was only then when I finally let him rest."
          After his death, a psychologist told Daniel Vick's daughter that her father is in heaven, an angel watching over her -- that God needed him to be up there with him, his mother said.
          "Maybe later," a neighbor said, "she will understand what happened."
