That's according to data from the U.S. Center for Disease Control and Prevention (CDC). > Monkeypox is a virus originally passed to humans from animals and usually seen in Central and West Africa. However, it is currently spreading in populations within non-endemic countries across the world, including rapidly in Europe and North America. Symptoms may include fever, headaches, muscle aches, swollen lymph nodes and exhaustion, followed by a pustulous skin rash that may scar. These symptoms are similar, but less clinically severe, to those of smallpox, which was eradicated in the 1980s.
