Colombia has declared a national health and economic emergency over a deadly yellow fever outbreak, with the government urging people to get vaccinated and take precautions while traveling over Easter weekend.

The mosquito-borne virus, which typically causes fever, muscle pains, nausea and headaches, is endemic to multiple countries in South America, including Colombia, where the current outbreak has had a high mortality rate.

Minister of Health, Guillermo Jaramillo told newsmen that at least 34 people have died among 74 confirmed cases since the start of the year, stressing that the virus has also spread beyond the rural regions traditionally considered at risk for outbreaks, making it a threat to more communities.
