Monkeypox was first discovered in 1958. Monkeypox is caused by an orthopoxvirus and is closely related to the virus that causes smallpox.
Currently, the world has 257 cases of Monkeypox, 10 within the United States. The CDC says it's currently monitoring cases around the world including Britain, Portugal, and Spain. Person-to-person transmission isn't common, but in England, scientists see evidence it's spreading through the community with cases that involve sexual contact.
According to WHO, if the virus establishes itself as a human pathogen, this could result in a high “public health risk”. Vaccination against Smallpox has been shown to protect against monkeypox. The world has an opportunity to stop this outbreak.
