Two thirds of the cases have been reported from six states—Texas, Louisiana, South Dakota, Mississippi, Michigan and Oklahoma. Forty percent of all cases are concentrated in Texas, according to the CDC.

First identified in Uganda in 1937, the virus manifests itself in a number of different ways and 80 percent of the time does not spark serious symptoms.

However, it can also cause potentially fatal complications such as meningitis or .
