Monkeypox (MPX)

Updated 8/10/22
Monkeypox - What You Need To KnowMPX is a rare disease caused by infection with the monkeypox virus.  Monkeypox can infect animals, such as monkeys and rodents, as well as humans.  The monkeypox virus belongs to the same group of viruses that cause smallpox and is not related to chicken pox.  The first case of  human monkeypox was recorded in 1970.  Since then, monkeypox has been reported in people in several other central and western African countries.  Prior to the current outbreak, nearly all monkeypox cases in people outside of Africa were linked to international travel to countries where the disease commonly occurs, or through imported animals. 

In May 2022, several clusters of monkeypox were reported in countries that don't normally report human monkeypox cases, including the United States.  There have been 219 cases reported in Maryland and nearly 9,500 cases reported in the United States.

Montgomery County is currently vaccinating a very small group of high-risk individuals. As more vaccine is received, there may be additional recommendations about vaccinating other residents. See the full press release for more information.


Montgomery County has developed a pre-registration survey to identify County residents who are interested in receiving a Monkeypox/ MPX vaccination AND are at risk for having been exposed to Monkeypox/MPX in the previous 4-14 days. Monkeypox is not a sexually transmitted infection (STI)  but is sexually associated.  Anyone can get Monkeypox/MPX, but with a limited vaccine supply, our priority is to protect those who may have already been exposed.  Our strategy (and pre-registration) will evolve as we learn more about who most urgently needs protection from Monkeypox/MPX.

Appointments are based on eligibility and vaccine supply and are not guaranteed.

Pre-registration survey is included in the vaccination section below.
