Puerto Rico Flu Epidemic Sparks Caution in USVI

A.J. Pike

USVI - Puerto Rico has declared a State of Emergency due to an influenza epidemic that has produced more than 42,000 confirmed influenza cases, over 3,000 hospitalizations, and 128 influenza-associated deaths as of the end of January 2026. Almost 46 percent of the reported cases have involved children.

In response, the V.I. Department of Health (VIDOH) is urging USVI residents to get vaccinated and to take all precautions due to frequent inter-island travel between the two U.S. Territories.

“What we are seeing in Puerto Rico is a sobering reminder that influenza is not a mild illness, it can be deadly, especially for those who are unvaccinated,” said Health Commissioner Justa Encarnacion in a press release. “Our Epidemiology wastewater surveillance system does not currently indicate an increase in cases in the Territory in comparison to our numbers from last year. However, we recognize that frequent travel between our islands (Puerto Rico) makes transmission of the disease easy. That is why we are urging residents to take preventative steps now.”

Puerto Rican health officials report that over 96 percent of the individuals who have died during the quick-spreading disease were not vaccinated. Hospitalizations have mainly involved children, the elderly and individuals with underlying chronic conditions, which has placed a significant strain on the Puerto Rican healthcare system. 

“What we are seeing in Puerto Rico reinforces what public health professionals have been touting all along - the flu vaccine saves lives,” stated Dr. Tai Haunte-Caesar, Chief Medical Officer for the Virgin Islands Department of Health. “We strongly encourage Virgin Islands residents who have not yet received their flu shot to speak with their healthcare provider as soon as possible. Influenza is often underestimated, but like COVID-19, it can lead to severe illness, hospitalization, and, in some cases, death.”

Influenza symptoms appear suddenly and can include: fever or chills, cough, sore throat, runny or stuffy nose, body aches, headache, fatigue, and in some cases vomiting or diarrhea. Mild cases can recover at home with rest, fluids, and over-the-counter meds. Seek emergency medical care if symptoms appear severe. Stay home when sick. Avoid work, school, childcare, and being in public until fully recovered and fever-free for at least 24 hours 

“While vaccination remains the most effective way to prevent severe illness from the flu, we also encourage residents, especially those who are immunocompromised or at higher risk, to consider wearing a mask in public settings as an added layer of protection,” said Commissioner Encarnacion. “Simple steps like staying home when sick, practicing good hand hygiene, and masking when appropriate can significantly reduce the spread of flu and help protect our most vulnerable community members.”  

The Department of Health’s Community Health Clinic is offering free flu shots to uninsured and underinsured residents. Appointments can be scheduled by calling: St. Croix: 340-712-0131; STT: 340-774-7477; STJ: 340-776-6400.
