Port of Spain, Trinidad and Tobago – Health officials in Trinidad and Tobago have confirmed a case of yellow fever in a deceased Red Howler monkey, prompting increased surveillance and preventative measures. Although no human cases have been detected, the finding serves as an important early indicator of potential viral activity within the country’s primate population and a reminder of the ongoing risk of mosquito-borne diseases. This discovery underscores the importance of proactive public health monitoring and vaccination efforts in the region.
The Trinidad and Tobago Ministry of Health (MOH) announced the confirmation on Tuesday, stating that the monkey tested positive for the yellow fever virus. Red Howler monkeys, common throughout the islands, can act as sentinels for the virus, meaning their infection can signal a broader presence of the pathogen in the mosquito population. The Aedes aegypti mosquito, a known vector for yellow fever, is widespread in Trinidad and Tobago, making vigilance crucial. This represents the first confirmed case in a primate in the country since 2015, according to the Pan American Health Organization (PAHO).
Understanding the Risk: Yellow Fever and its Transmission
Yellow fever is a viral hemorrhagic disease transmitted by infected mosquitoes. The virus is endemic in parts of Africa and South America and while it was largely eradicated from the Americas through vaccination programs, outbreaks can still occur, particularly in unvaccinated populations. The disease gets its name from the jaundice – yellowing of the skin and eyes – that affects many patients.
Symptoms typically develop 3–6 days after infection and initially resemble the flu, including fever, chills, headache, backache, and muscle aches. However, in approximately 15% of cases, the illness progresses to a more severe form, characterized by high fever, jaundice, bleeding, shock, organ failure, and potentially death. Currently, there are no specific antiviral medications to treat or cure yellow fever; care focuses on managing symptoms and preventing complications. The Centers for Disease Control and Prevention (CDC) notes that supportive care, including fluids, oxygen, and blood products, is essential for severe cases.

Trinidad and Tobago’s Response and Prevention Efforts
Following the confirmation of the case in the Red Howler monkey, the Ministry of Health has initiated enhanced surveillance activities in the affected areas. This includes increased monitoring of both mosquito populations and primate health. Vector control measures, such as fogging and larviciding, are also being intensified to reduce mosquito numbers and limit the potential for further transmission.
“The Ministry of Health is taking this situation very seriously,” stated a press release issued by the MOH. “We are working diligently to contain any potential spread of the virus and protect the population. We urge the public to take preventative measures to avoid mosquito bites.”
Protecting Yourself: Mosquito Bite Prevention
Preventing mosquito bites is the most effective way to avoid yellow fever and other mosquito-borne illnesses. Public health officials recommend the following measures:
- Use Insect Repellent: Apply insect repellent containing DEET, picaridin, IR3535, or oil of lemon eucalyptus to exposed skin, and clothing.
- Wear Protective Clothing: Cover up with long sleeves, long pants, and socks when outdoors, especially during peak mosquito activity hours (dawn and dusk).
- Eliminate Standing Water: Mosquitoes breed in standing water. Regularly empty and clean containers that hold water, such as flower pots, tires, and gutters.
- Ensure Proper Screening: Install and maintain screens on windows and doors to keep mosquitoes out of your home.
- Sleep Under a Mosquito Net: If you are sleeping in an unscreened area, use a mosquito net.
Vaccination: The Best Defense Against Yellow Fever
The yellow fever vaccine is highly effective in preventing the disease and is recommended for travelers visiting areas where yellow fever is endemic. The World Health Organization (WHO) recommends a single dose of the vaccine for individuals aged 9 months and older living in or traveling to at-risk areas. Find more information about the yellow fever vaccine from the WHO. The vaccine is available at select travel clinics and public health facilities in Trinidad and Tobago.
The Ministry of Health is currently reviewing its vaccination strategies to determine if targeted vaccination campaigns are necessary in specific areas. They are also working with regional and international partners, including PAHO, to monitor the situation and share information.
The Ministry of Health will provide further updates as the situation evolves. The next official update is scheduled for next week, where they will present findings from ongoing surveillance efforts.

We encourage readers to share this information with their communities and remain vigilant in protecting themselves from mosquito bites.
