Three months after the first reports of monkeypox cases outside the African continent, five resulted in death in four different countries, between July 29 and August 2. If the precise causes of death have yet to be studied, certain elements have nevertheless been communicated.
In Brazil, it is a 41-year-old man suffering from “serious comorbidities” ; in Peru, an HIV-positive man who abandoned his treatment against HIV died on Monday from being infected with monkeypox. In India and Spain, three people have died with symptoms of encephalitis, an inflammation of the tissues that allow brain function. These deaths are in addition to the five deaths designated in Africa since the beginning of the year.

“It is difficult to predict the future, but we have now taken from a large sample size and the case fatality rate for this year is 0.05%, according to the figures reported”, says Chloe Orkin, director of the Share project at Queen Mary University, London, and lead author of the largest study of the recent monkeypox outbreak published in The New England Journal of Medicine. Until then, the case fatality rate, that is to say the number of people who died among the infected population, was revealed by the World Health Organization (WHO) between 3% and 6% for the last African epidemics. monkeypox.
