正在发生什么

Yellow fever activity is ongoing in Colombia, especially in Tolima, as part of the wider resurgence in the Americas described by WHO. WHO said Colombia had reported 60 confirmed cases and 24 deaths by 2025-04-26, and 83 confirmed cases and 37 deaths since early 2024, with most 2025 cases in Tolima. In WHO's 2026 global update, Colombia was still the most affected country in the Americas through 2026-05-26. The newest figures available here are from a 2026-09-21 media report citing preliminary Instituto Nacional de Salud data through 2026-09-08: media report 58 confirmed cases, 27 deaths, 1,183 probable cases, and 32 confirmed monkey infections, unverified. Officials describe vaccination as the main control measure, alongside surveillance, laboratory testing, case management, risk communication, and monitoring of animal activity, and CDC posted a Level 2 travel notice for Colombia on 2026-09-18.

谁会受影响以及如何传播

Yellow fever is a mosquito-borne viral disease spread by infected day-biting mosquitoes, and WHO says transmission is maintained mainly through mosquito-primate cycles with spillover into people. The current activity described in the sources is largely sylvatic spillover, especially in forested and rural settings. The sources also note a risk of spread into new areas, including urban centres, where competent vectors are present and population immunity is low, and they specifically mention travel by unvaccinated visitors in the Colombia context. Vaccination is described as the primary means of prevention and control.
