Sloth fever is spreading in the U.S.; is it life-threatening? What are its symptoms, and is there a vaccine? Will there be a travel ban?

The Oropouche virus, commonly referred to as sloth fever, is a disease that is spread by mosquitoes and has been identified in the US. The virus was recently discovered by tourists coming back to the United States from Cuba, according to The Associated Press. There have been no confirmed deaths.

Besides being reported in South America and the Caribbean, the Oropouche virus is endemic in the Amazon basin. The CDC states that since then, it has had limited circulation in parts of South America, especially in forested areas.

The disease is usually transmitted by mosquitoes and midge bites like small flies, especially the Culicoides paraensis species. It has been determined that three-toed sloths and birds are natural reservoirs for the Oropouche virus, meaning they serve as the disease's hosts.

Dr Marc Siegel, a senior medical analyst for Fox News and clinical professor of medicine at NYU Langone Medical Center, told Fox News Digital that the virus doesn't spread from person to person, thus it is non-contagious.

Oropouche, an arbovirus, poses a risk to fetuses due to birth defects. Symptoms include fever, headache, muscle aches, stiff joints, chills, and a rash. Symptoms usually begin within four to eight days of being bitten and last for three to six days. In severe cases, patients may develop meningitis, encephalitis, or other neuroinvasive diseases. Most people who contract Oropouche will recover without long-term effects.

The Pan American Health Organization issued an alert advising people to take preventive measures, such as using repellents, covering their arms and legs, and using fine mesh mosquito nets. They should also take extra precautions during outbreaks, especially for vulnerable groups like pregnant women.

There are no vaccines or treatments for Oropouche, so the best prevention is to avoid bites from midges and mosquitoes.
