Texas patient becomes U.S.' first monkeypox case since 2003

A Dallas, Texas, resident who recently returned from Nigeria has tested positive for monkeypox, a rare virus similar to smallpox, local officials said Friday. Though this is the first confirmed case of the virus in the U.S. since 2003, officials said the public should not be concerned. 

"While rare, this case is not a reason for alarm and we do not expect any threat to the general public," Dallas County Judge Clay Jenkins said in a statement from Dallas County's health department. Because passengers were wearing masks on the flight and in the airport, the health department said, "It's believed the risk of spread of monkeypox via respiratory droplets to others on the planes and in the airports is low."  Monkeypox, which is in the same family of viruses as smallpox, is a rare but potentially deadly viral infection that begins with flu-like symptoms and progresses to a rash on the face and body, according to the CDC. It tends to last two to four weeks. People who do not have symptoms are not capable of transmitting the virus, the health department said.
