“Monkeypox causes a flu-like array of symptoms, but also comes with a distinctive rash; one telltale sign is the fact that lesions often appear on the palms of hands. So far it seems that the cases are being caused by viruses from the West African clade, which triggers milder disease than the other family of viruses, called the Congo Basin clade. All monkeypox viruses are cousins of the one that caused smallpox, the only human virus to have been eradicated.”-Helen Branswell, “A CDC expert answers questions on monkeypox.” STAT. May 19, 2022
In sum, monkeypox is not like COVID-19. It requires close contact. It can be transmitted by respiratory droplets when there are sores in the mouth, but it’s not the primary vector. The West African clade has a 1% fatality rate, which is much less than the 10% of the Congo Basin clade. The high death rate probably is due to West Africa’s poor access to health care.
There’s already a vaccine for monkeypox. This is not going to be a global pandemic like COVID-19. But, it is a serious disease, and it is prevalent in an unprecedented level.
If you must know more about it WHO has a monkeypox course.
