"CDC health officials are now working vigorously to trace contacts of anyone directly exposed to a Dallas resident who recently returned to the US on a trip to Nigeria. The man is now in isolation at a Dallas hospital after testing positive for an extremely rare disease known as Monkeypox - said to be the first ever case of its kind in Texas.
It's also the first case seen inside the United States in two decades, with the last significant outbreak in 2003 including 47 reported human cases. The infected person flew into Atlanta international airport on July 8, and then on to Dallas Love Field the next day.
NBC details further of the rare disease:
It usually takes seven to 14 days after a person is exposed to the monkeypox virus to develop symptoms, according to the CDC, which begin like many other viruses: fatigue, fever, headache, muscle aches.
Within a week of symptom onset, an infected person develops a bumpy, raised rash that often spreads to the entire body. The person is considered contagious until those raised bumps have scabbed over and fallen off.
It's this lengthy period in which a person may not know they have it which may allow for a rapid undetected outbreak." ZeroHedge
