Study says Maria killed 4,645 in Puerto Rico
CAGUAS, Puerto Rico — At least 4,645 people died as a result of Hurricane Maria and its devastation across Puerto Rico last year, according to a new Harvard study released Tuesday, an estimate that far exceeds the official government death toll, which stands at 64.
The study, published in the New England Journal of Medicine, found that health care disruption for the elderly and the loss of basic utility services for the chronically ill had significant impacts across the U.S. territory, which was thrown into chaos after the September hurricane wiped out the electrical grid and had widespread effects on infrastructure. Some communities were cut off for weeks amid road closures and communications failures.
Researchers in the United States and Puerto Rico, led by scientists at the Harvard T.H. Chan School of Public Health and Beth Israel Deaconess Medical Center, calculated the number of deaths by surveying nearly 3,300 randomly chosen households across the island and comparing the estimated post-hurricane death rate to the mortality rate for the year before. Their surveys indicated that the mortality rate was14.3 deaths per 1,000 residents fromSept. 20 through Dec. 31, 2017, a 62 percent increase in the mortality rate compared to 2016, or 4,645 “excess deaths.”
“Our results indicate that the official death count of 64 is a substantial underestimate of the true burden of mortality after Hurricane Maria,” the authors wrote.
The official death estimates have drawn criticism from experts and local residents, and the new study criticized Puerto Rico’s methods for counting the dead — and its lack of transparency in sharing information — as detrimental to planning for future natural disasters. The authors called for patients, communities and doctors to develop contingency plans for natural disasters.
Maria caused $90 billion in damage, making it the third-costliest tropical cyclone in the United States since 1900, the researchers said.
More than eight months after Hurricane Maria devastated Puerto Rico, the island’s slow recovery has been marked by a persistent lack of water, a faltering power grid and a lack of essential services — all of which have imperiled the lives of many residents who have been struggling to get back on their feet, especially the infirm and those in remote areas, some of which were the hardest hit in September.
Counting the dead in such natural disasters is always a difficult task, even under ideal circumstances; in Puerto Ricoit washampered by numerous systemic failures and what the Harvard researchers found was a complex method for certifying the deaths in San Juan. The researchers noted that the Centers for Disease Control and Prevention says that deaths can be directly attributed to storms like Maria if they are caused by forces related to the event, from flying debris to loss of medical services; in Puerto Rico such deaths continued for months.
