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.

In July, monkey pox was discovered in Texas by a traveler who came from Nigeria. That person was hospitalized, said the CDC in July. His current condition is not known. People who came in contact with him were tracked down.
