According to the new study by New England Journal of Medicine Conducted in 16 countries, 95% of infections result from sexual contact.
The vast majority of recent cases of monkeypox were transmitted through sexual contact, according to the largest study to date, which also shows that the vast majority of those affected were gay men.
This study published on Thursday, July 21 in the scientific journal New England Journal of Medicine, analyzed data from more than 520 cases in 16 different countries (Canada, USA, Europe, etc.) spanning two months between late April and late June. Overall, according to the doctors treating these cases, 95% were due to sexual contact.
“She can be caught by any close physical contact”
“It is important to emphasize that monkeypox is not a sexually transmitted infection in the traditional sense; it can be caught by any close physical contactwith an infected person, said the study’s lead author, John Thornhill. “But our work suggests that the bulk of transmission so far has been related to sexual activity.The observed skin lesions, mainly anal, on the genitals or on the mouth, could represent the vaccination zones, the study notes. Semen analysis from 32 people showed the presence of viral DNA in 29 cases, but further studies are needed to determine if transmission can actually occur this way.

Overall, 98% of the cases examined were gay or bisexual men. The average age was 38 years. Almost 41% were infected with HIV, the AIDS virus, but the vast majority of them were on treatment. No deaths were recorded among the cases studied, and most were mild cases. Despite everything, 13% were hospitalized. The main reasons were anorectal pain or skin infections. But then no serious complications were observed. In 23 people with a clear history of their infection, the incubation period (before the first symptoms appeared) was one week – but it could range from 3 to 20 days.
As previously reported, the study highlights that the observed symptoms differ from those typically seen in African countries where the disease is endemic. First of all, the fact that the rashes are concentrated in certain areas. Lesions were observed in 95% of people, including the genito-anal area in 73% of cases. The number of lesions varied greatly from person to person, but was generally less than 10. The authors therefore warn of the risk of misdiagnosis, as they believe they are dealing with a sexually transmitted infection.
