Peruvian health authorities have sounded an alarm over an increase in yellow fever cases in the Amazon region, affecting areas such as Huanuco, San Martin, and Amazonas. As of April 1, 2025, the number of yellow fever cases reported surpasses those of 2024. This year, 29 cases have been confirmed, resulting in ten fatalities. Comparatively, 2024 saw 19 confirmed cases and nine deaths in total.
The yellow fever virus is transmitted via the bite of an infected mosquito. According to the U.S. Centers for Disease Control and Prevention (CDC), vaccination is advised for all individuals traveling to regions with a risk of yellow fever, which helps prevent both yellow fever and other transmissible diseases like Dengue. The CDC highlights that there is no specific cure for yellow fever.
The initial symptoms include fever, chills, severe headache, back pain, and general body aches. More severe symptoms involve high fever, jaundice, bleeding, shock, and potential organ failure. Medical consultation is recommended if yellow fever is suspected.
Information regarding yellow fever and affected regions is available on the CDC and the Peruvian Ministry of Health's websites. Travelers are encouraged to ensure their vaccinations are up to date and follow preventive measures against mosquito bites.
"Ensure you are vaccinated against yellow fever before traveling to areas with risk of transmission," advises the alert. Additionally, "pregnant travelers should discuss potential risks and travel plans with their healthcare provider."
For medical aid, although the U.S. Embassy does not endorse specific practitioners, a list of local doctors is accessible on their website. The U.S. Embassy in Lima advises enrollment in the Smart Traveler Enrollment Program (STEP) for those who wish to receive updates.
