More than 20 people returning to the US from Cuba have been infected with a virus transmitted by bugs in recent months, federal health officials said Tuesday. None have died, and there is no evidence that it's spreading in the United States. But officials are warning US doctors to be on the lookout for the infection in travelers coming from Cuba and South America, the AP reports. Here's a look at the illness and what sparked the alert:
- What is Oropouche virus? Oropouche is a virus that is native to forested tropical areas. It was first identified in 1955 in a 24-year-old forest worker on the island of Trinidad, and was named for a nearby village and wetlands. It has sometimes been called sloth fever because scientists first investigating the virus found it in a three-toed sloth, and believed sloths were important in its spread between insects and animals.
