Droplets a 'minor' route of mpox transmission

The WHO on Tuesday said droplets were a minor route of transmission for mpox compared to physical contact, adding that more research was needed to understand how the outbreak is spreading.

The UN health agency says on its website that mpox spreads between people mainly through close physical contact with someone who has the virus.

"Close contact includes skin-to-skin (such as touching or sex) and mouth-to-mouth, or mouth-to-skin contact (such as kissing)," it says.

It can also include "being face-to-face with someone who has mpox (such as talking or breathing close to one another, which can generate infectious respiratory particles)".

WHO spokeswoman Margaret Harris said Tuesday that if a person with the virus had lesions, "if you're talking closely to someone, breathing on them, physically close, face-to-face, there is a possibility" of viral spread, "but this is a minor source".

The WHO recommends the use of facemasks for those with mpox, their close contacts and health workers treating them.
