Spain confirms first human transmission of mpox clade 1b outside Africa

Spain has reported the first case of mpox clade 1b spreading from person to person outside of Africa.

A 49-year-old man in Madrid got sick with mpox, even though he had been vaccinated twice and hadn't traveled to places where mpox is common.

He got it from sexual contact with partners who also hadn't traveled.

This is different from other cases because usually, people get mpox by traveling to Africa or being near someone who did.

Health officials are worried and want people to be careful, especially those who might be more at risk, like people with HIV or many sexual partners.

There have been many new cases and some deaths around the world recently.
