Mpox returns in new countries — virus has now hit 145 nations and nearly 190,000 cases

A fresh outbreak of mpox has been confirmed in Guinea-Bissau — the country's first — pushing the virus back into global headlines. Since 2022, nearly 190,000 lab-confirmed cases have been reported across 145 countries. Children appear to be particularly affected in the new cases, a shift from previous outbreaks. Before 2022, mpox was largely confined to a handful of endemic African nations.
