Colombia has declared a nationwide health emergency as a yellow fever outbreak has led to at least 34 fatalities, according to official reports. This dangerous virus, transmitted by infected mosquitoes, can be prevented through a vaccine that offers long-lasting protection. As many Colombians prepare for Easter travels, especially to regions where mosquitoes thrive, Health Minister Guillermo Alfonso Jaramillo emphasizes the necessity of vaccination. Those traveling to high-risk areas must provide proof of their vaccination. Currently, there are 74 confirmed yellow fever cases, a drastic increase compared to recent years, where only two were reported in 2023 and none from 2019 to 2022. This outbreak presents a mortality rate of nearly 50% among infected individuals, particularly in Tolima province, known for its coffee plantations and tourist attractions. President Gustavo Petro has warned unvaccinated individuals to avoid high-risk areas during Easter. Although many people recover from initial symptoms, about 15% may progress to a more severe phase, with a significant risk of death. The World Health Organization advises vigilance as symptoms can often mimic other diseases.
