DALLAS (CBSDFW.COM) - The Dallas County health department has reported its first locally transmitted case of the monkeypox virus after a man who attended the Daddyland Festival tested positive. He traveled from out-of-state for the four-day, Fourth of July circuit party. Health officials said the man went to a Dallas hospital with a rash and was diagnosed through laboratory testing done. Given the size of the Daddyland Festival, others who attended the events could have been exposed to monkeypox and, possibly, infected.
