CDC health alert (level 2) — Yellow Fever (Colombia)

If you are currently on site, you should be aware that yellow fever is transmitted through mosquito bites, particularly during dawn and dusk hours. Travellers in the affected area face increased exposure risk. Seek immediate medical attention if you develop symptoms such as fever, headache, muscle pain, or jaundice, and inform healthcare providers of your location and travel history.

Follow local health authority guidance and CDC recommendations for your area. Ensure you have appropriate mosquito protection measures in place, including insect repellent, long clothing, and staying in screened or air-conditioned spaces when possible. Consult local health authorities about vaccination eligibility if you have not already done so. This alert is based on information from the CDC travel health division.
