This issue of HTB includes several articles about the recent outbreak of monkeypox (MPX).

WHO has already confirmed over 900 cases in 28 countries where MPX is not endemic.

By 1 June 2022, the UK has so far reported the highest number of cases (220), followed by Spain (135) and Portugal (100). These are nearly all in, or connected to, London, Madrid and Portugal.

The majority of cases (>90%) are in gay men.

Transmission rapidly developed through sexual networks and then international travel, though not as a sexually transmitted infection. Although MPX DNA has been detected in semen (in four early cases in Italy), saliva is more likely is perhaps a more likely route in a sexual setting than genital fluids (both through kissing and oral sex).

Other risks are direct contact with spots/ulcers or from breathing droplets (if sharing poorly ventilated rooms for more than three hours (including in shared households), or sharing clothes, towels and bedding.

comment

The prompt health care responses in the UK and other countries are focussed not only on tracing and managing cases linked to new network but also on preventing MPV from infecting other animals.

Over the next few weeks it will becomes more clear whether the rapid response has contained infections and prevented the infection from becoming endemic.
