If you are a UK resident and have read certain headlines over the past few weeks, you might be wondering – What the hell is monkeypox? And should I be worried?
That is because three people in the UK have been admitted to hospital with the virus in the last month alone. Two contracted the disease in Nigeria (where there is currently an outbreak) in completely unrelated but coincidental cases. The third is a healthcare worker who helped care for one patient at Blackpool Victoria Hospital. They are all being looked after by tropical disease specialists.
First thing's first – don't worry. British medical experts have confirmed that these cases aren't about to trigger a national outbreak and Public Health England has said the general public is not at risk.
"The fact that only one of the 50 contacts of the initial monkeypox-infected patient has been infected shows how poorly infectious the virus is," Jonathan Ball, a professor of molecular virology at the University of Nottingham, UK, told BBC News.
So now that's settled, what is monkeypox?
It's caused by the monkeypox virus, a less severe relative of the smallpox virus, which (shocker) was first identified in monkeys. It can also be caught from infected rats, squirrels, and other rodents, which are sometimes eaten as bushmeat, as well as contaminated objects.
There are two main strains of monkeypox (West African and Central African) and while there have been sporadic outbreaks across 10 African countries since the 70s, it rarely crops up outside the continent. This is the first time it has been reported in the UK.
Symptoms may include fever, headache, and an itchy rash that will often appear on the face before spreading to other parts of the body. Like the chickenpox rash, it turns into blisters and then scabs before it falls off, sometimes leaving scars. The illness usually lasts between two and three weeks.
