The Department of Health said last week that 99% of the cases recorded in the United States concern men who have sex with men. This population is, despite risks of stigmatization, the priority target for vaccination.
They are also a priority for preventive actions organized by the authorities, aiming in particular to establish a better knowledge of the symptoms and to suggest reducing their number of sexual partners between now and their vaccination.
About 14,000 doses of an antiviral initially developed against smallpox, tecovirimat, have been delivered, even if its effectiveness on monkeypox is currently poorly known.

The first symptoms of monkeypox are a high fever, swollen lymph nodes, and a chickenpox-like rash.
