The story at a glance


  • There are more than 6,000 cases of monkeypox in the United States

  • The monkeypox virus can cause a range of symptoms including fever, skin lesions and headaches.

  • A recent article details the symptoms of more than 500 cases in 16 countries.

According to the Centers for Disease Control and Prevention, 6,326 cases of monkeypox infection have been reported in the United States. In an article published in the New England Journal of Medicine, researchers compiled information on symptoms of 528 monkeypox virus (MPV) infections from 43 sites in 16 countries during the period April 27. to June 24 of this year.

Overall, 95% of those infected had rashes or skin lesions, with 64% having less than 10 lesions. Seventy-three percent had lesions in the genital area and 41% had lesions in the mouth. Fifty-five percent of people had lesions on the torso, arms or legs. Lesions were present on the palms and soles of the feet in 10% of cases. A small number of people, 54, had a single genital lesion. There were no deaths among the patients.

Patients also reported fever (62%), lethargy (41%), muscle aches (31%) and headache (27%) as symptoms.

For 23 of the cases, there was information on the exposure history which showed that the incubation period could range from three to 20 days. The researchers estimate that the median incubation period was seven days.

Seventy people, or 13% of cases, were hospitalized, the main reason being pain management. Eighteen people had soft tissue superinfections.

MPV is mainly spread by close physical contact. This study notes that the virus was found in seminal fluid in 29 of the 32 samples that were tested, but there is not enough knowledge about virus transmission to say whether it can be transmitted through bodily fluids. . As epidemiologist Katelyn Jetelina says in her newsletter, “Current evidence shows that MPV transmission can occur in many ways, but what’s possible isn’t always likely. The epidemiological data show a very close and prolonged exposure absolutely dominating the transmission networks.
