The World Health Organization and the British government have been working together to examine the outbreak, which has resulted in seven cases in the UK.
In this case, health experts have noticed that some of these infections may have been transferred through sexual contact, which would be a new development in our understanding of how this virus is spread.
"23 potential monkeypox cases" have been found in the Madrid region, indicating that all of them were transmitted through sexual activity, according to a statement from health authorities.
Portugal's health ministry reported that an additional 20 instances of Monkeypox, an endemic disease found in portions of Central and Western Africa, have been found in the Lisbon area.
It is common for Monkeypox to begin on the face and spread to other body regions, causing a rash and a fever. For the vast majority of people, the sickness subsides in weeks.
The UK Health Security Agency (UKHSA) has discovered four new instances, a public health agency since three cases were found in May.
According to the report, men who have had sex with another man or self-identify as gay or bisexual constituted all four of the new cases.
