- The World Health Organisation (WHO) on Aug 27 said droplets were a minor route of transmission for mpox compared with physical contact, adding that more research was needed to understand how the outbreak is spreading.

The WHO

declared an international emergency

over mpox on Aug 14, concerned by the surge in cases of the clade Ib strain in

the Democratic Republic of Congo

and its spread to nearby countries.

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 on Aug 27 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”.

Instead, “what we’re seeing is the close, physical skin-to-skin” contact as the chief route of transmission, she told a briefing in Geneva.

“When you’re talking to somebody, you’re spitting out droplets”, but “it’s not a very major form of transmission – and it’s not a... through-the-air, long-distance sort of transmission”.

“More research is needed to fully understand the transmission dynamics,” Dr Harris added.

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