Monkeypox self-diagnosis abilities, determinants of vaccination intention and self-isolation intention after diagnosis among MSM in the Netherlands

Monkeypox is a zoonotic disease and leads to a smallpox-like disease in humans. The current epidemic in European countries requires informed responses. We investigated the ability to self-diagnose a potential monkeypox infection, and determinants of vaccination intention and self-isolation intention after exposure among MSM in the Netherlands. We found that about half were able to self-diagnose monkeypox, that 72% had a high intention to get vaccinated and 44% to self-isolate after monkeypox exposure. Determinants went beyond mere risk behaviour criteria. Data availability Data is available upon request.
