The monkeypox virus, or MPX, has arrived in Delaware, according to the state Division of Public Health.

The state agency announced on Tuesday that a 41-year-old New Castle County man tested positive for MPX in test results received this week. This positive case is considered probable until testing is confirmed by the Centers for Disease Control and Prevention, according to the DPH news release.

The Delaware man did not report any travel or exposure to someone known to have MPX, but he was likely exposed to the virus after close intimate contact with an individual in early July, DPH said. The man is self-isolating and DPH is working with him to identify any possible close contacts.

DPH is also working with the CDC to confirm the course of treatment for this individual.

“The Delaware Division of Public Health has prepared to respond to MPX cases,” said DPH Interim Director Dr. Rick Hong. “As we work to confirm our first case in the state, we encourage Delawareans to be aware of being in close intimate contact with individuals who have rashes or flu-like symptoms. We will continue to monitor this situation closely.”’

The first case of human monkeypox virus infection in Maryland was reported in mid-June, and the state currently has 22 cases, according to CDC data. This data shows that New Jersey reported 11 cases and Pennsylvania has 27 people who have been infected.
