Health officials in Thailand have confirmed a case of the Clade Ib version of mpox, which led the World Health Organization to declare a global health emergency.
This is the second case of this deadlier version reported outside Africa, following a recent case in Sweden.
Clade Ib has a higher death rate of 3% compared to the 0.2% death rate of Clade IIb reported in 2022.
About Mpox Clade Ib:
- The Clade IIb variant, common in 2022, spread mainly through sexual contact, affecting men who have sex with men. Behavioural changes and vaccinations eventually reduced its spread.
- Clade Ib appears to spread mainly through heterosexual sex, while another subtype, Clade Ia, spreads through household contact, exposure to affected animals, and sexual contact. Young children are particularly vulnerable to Clade Ia.
