Thousands of cases of the Oropouche virus, dubbed 'Sloth Fever,' have been reported around the world this year, including 21 in the US and 19 in Europe, all of whom are believed to have contracted the virus while traveling to Cuba and Brazil.
Sloth Fever comes from insects like midges and mosquitoes, who then transmit it when they bite animals including birds, rodents, sloths, and humans. Symptoms include fever, chills, headaches, sensitivity to light, and vomiting, among others.
