Mpox (monkeypox) is a virus that can be spread from animal to human, but also between humans. In the summer and fall of 2022, an unusually large number of cases were confirmed in many countries. No new cases have been confirmed in Sweden since the end of January this year. On May 11, WHO announced that mpox was no longer considered a public health emergency of international concern (PHEIC). RFSL has compiled a list with answers to common questions about mpox.

What is mpox and how does it spread?

Mpox is a virus that can spread from animal to human and between humans. It’s a virus that does not spread easily between people. Foremost, the virus is transmitted through close physical contact. The virus is believed to spread through large drops from the airways, through bodily fluids and fluid from blisters.

How common is it?

In Sweden, 260 cases of mpox have been confirmed. Most cases have been reported in the Stockholm region.

What are the symptoms?

Common symptoms are skin rashes with blisters and sores on the genitals, anally, in the face or around the mouth, or on other parts of the body. Other common symptoms are fever, head and muscle aches and swollen lymph nodes.

The incubation period for mpox, i.e. the time it takes from when the virus enters the body to when you start experiencing symptoms, is usually 6-13 days but may vary between 5 and 21 days.

How dangerous is it?

The symptoms are often mild, but can cause pain and discomfort. The infection often heals by itself within two to four weeks. Out of the to-date confirmed cases, very few have become seriously ill. There have been cases where people have had to be hospitalized, due to problems with eating caused by painful blisters in the mouth.

What should I think about?

It’s good to be watchful of symptoms. If you’ve had new sexual contacts over the past few weeks and experience potential symptoms, you should contact 1177 or the nearest sexual health clinic.

Transmission can be prevented by avoiding close physical contact, including sexual contact, with people who carry the virus. 


Vaccines are offered to men who have sex with men with multiple sex partners. If you’re interested in getting the vaccine, reach out to your local infectious disease/STD clinic to learn how to access it in your region.
