Monkeypox outbreak in U.K., Europe and U.S

Monkeypox can be a nasty illness; it causes fever, body aches, enlarged lymph nodes and eventually "pox," or painful, fluid-filled blisters on the face, hands and feet. 

One version of monkeypox is quite deadly and kills up to 10% of people infected. 

Typically, people catch monkeypox from animals in West Africa or central Africa and import the virus to other countries. 

Person-to-person transmission isn't common, as it requires close contact with bodily fluids, such as saliva from coughing or pus from the lesions. So the risk to the general population is low 

there's evidence the virus could be spreading through a new route: sexual contact. 

We are particularly urging men who are gay and bisexual to be aware of any unusual rashes or lesions and to contact a sexual health service without delay," epidemiologist Hopkins said in the UKHSA's statement. 

Scientists at the U.S. Centers for Disease Control and Prevention are watching the outbreak in Europe closely. 

Could the virus become more transmissible and thus more of a global threat?

"Oh, yes," Hooper says. "Every time there's an outbreak — and the more people get infected — the more chances monkeypox has to adapt to people," he says.

How do you catch it?

Primarily, from an animal bite, scratch or contact with the animal's bodily fluid. Then the virus can spread to other people through coughing and sneezing or contact with pus from the lesions.
