It transmits via direct contact with infectious sores or scabs and through body fluids, like droplets from people's mouths. Monkeypox relies on prolonged close contact to spread, meaning it can be passed on during sex - although it is not classified as a sexually-transmitted infection.

Gay and bisexual men should avoid oral sex and positions that involve face-to-face contact to limit the spread of monkeypox, a charity has said.
