The World Health Organization classified the escalating outbreak of the once-rare disease as an international emergency in July; the U.S. declared it a national emergency last week.
Outside of Africa, 98% of cases are in men who have sex with men. With only a limited global supply of vaccines, authorities are racing to stop monkeypox before it becomes entrenched as a new disease.
CAN MONKEYPOX BE CONTAINED?
Theoretically, yes. The virus does not spread easily and there is a vaccine. But there are only about 16 million doses available now and only one company makes the shot.
Except for Africa, there is no sign of sustained monkeypox transmission beyond men who have sex with men, meaning that stopping spread among that group could effectively end the outbreak. Last week, British scientists said there were “early signs” the monkeypox cases in the U.K. — which once had the world’s biggest outbreak outside Africa — had peaked.
IS THIS ANOTHER PANDEMIC?
No. A pandemic means that a disease outbreak has spread to the entire world. Monkeypox does not transmit as quickly as the coronavirus and stopping it will not require dramatic interventions like the COVID-19 lockdowns.
WHO’s Director-General Tedros Adhanom Ghebreyesus said he declared monkeypox an emergency in part to prompt countries to take the epidemic seriously, saying there is still an opportunity to contain the disease before it becomes a global problem.
HOW DOES IT SPREAD?
Monkeypox spread typically requires skin-to-skin or skin-to-mouth contact with an infected patient’s lesions. People can also be infected through contact with the clothing or bedsheets of someone who has monkeypox lesions.
It also can be spread through contact with respiratory droplets, but scientists are still trying to figure out how often that happens. British health officials say they haven’t confirmed any instances of airborne transmission.
WHO IS GETTING INFECTED?
A large percentage of cases have been in gay and bisexual men. The initial outbreaks in Europe and North America were likely triggered by sex at two raves in Spain and Belgium.
According to the U.S. Centers for Disease Control and Prevention, 99% of monkeypox cases in the U.S. are men. Of those, 94% reported sexual contact with other men in the three weeks before they developed symptoms.
Still, anyone can catch the virus if they are in close contact with an infected person or fabrics that touched an infected person.
WHO IS GETTING VACCINATED?
With supplies limited, health officials are not recommending mass vaccination. They are suggesting the shots for health workers, people who have been in close contact with an infected person, and men at high risk of catching monkeypox.
Officials are also trying to stretch supplies of the vaccine, Jynneos. It requires two doses, but many places are only giving one dose.
U.S. health officials on Tuesday authorized a new strategy that would allow health professionals to vaccinate up to five people — instead of one — with each vial. The approach uses just a fraction of the typical amount of vaccine and administers it with an injection just under the skin rather than into deeper tissue. Recipients would still get two shots a month apart.
WHAT ELSE CAN I DO TO LOWER MY RISK?
WHO’s Tedros recommended that men at risk of catching monkeypox consider making “safe choices” and reducing their sexual partners “for the moment.”
