Bogotá, April 17, 2025 — The Colombian government has declared a nationwide health and economic emergency in response to a severe outbreak of yellow fever, a mosquito-borne viral disease that has claimed 34 lives among 74 confirmed cases since the beginning of the year. The Ministry of Health has urged the public to get vaccinated and take necessary precautions, especially during the upcoming Easter travel period.
Health Minister Guillermo Jaramillo revealed on state-run Radio Nacional de Colombia that the yellow fever outbreak is particularly alarming due to its high mortality rate, which approaches 50% among those infected. The virus, transmitted primarily by Aedes aegypti mosquitoes, has traditionally been confined to rural areas but is now spreading to more communities, expanding the threat beyond previously recognized high-risk zones.
The most critical situation is unfolding in the coffee-growing department of Tolima, where cases have surged from just four in September 2024 to 22 by mid-April 2025. This region has become the epicenter of the outbreak, with several municipalities reporting multiple cases, many of which involve individuals engaged in agricultural work and who had no documented history of vaccination.
In a decisive move, President Gustavo Petro announced an economic emergency alongside the health decree and mandated that all travelers entering or leaving Colombia must carry proof of yellow fever vaccination. He cautioned unvaccinated individuals against traveling to high-risk areas, particularly the Tolima coffee region, during the Easter holidays. President Petro also attributed the spread of the disease to climate change, which has facilitated the movement of mosquito vectors to higher altitudes.
International health bodies have taken note of the escalating situation. The United States Centers for Disease Control and Prevention (CDC) recently upgraded its yellow fever alert for South America to level two out of four, signaling the need for enhanced precautions. The CDC advises travelers to Colombia, Bolivia, and Peru to receive yellow fever vaccinations or booster shots at least 10 days prior to travel and to protect themselves against mosquito bites.
The Pan American Health Organization (PAHO) has also issued epidemiological alerts highlighting increased yellow fever activity in the region, urging countries to intensify surveillance, vaccination campaigns, and clinical management of severe cases to contain the outbreak.
Key Symptoms and Risks
Yellow fever typically presents with fever, muscle pain, nausea, and headaches. While many cases are mild, approximately 15% of infected individuals develop severe illness, which can lead to liver failure, bleeding, shock, and death. The incubation period ranges from 3 to 6 days.
Government Measures
-
Declaration of national health and economic emergencies
-
Mandatory vaccination card for all travelers crossing Colombian borders
-
Public advisories against travel to high-risk areas for unvaccinated individuals
-
Increased vaccination campaigns targeting at-risk populations
The Colombian government continues to monitor the situation closely and emphasizes the critical importance of vaccination and mosquito bite prevention to curb the spread of this potentially fatal disease.
