Portugal recorded community transmission of the 1b subvariant of the mpox virus, meaning the virus is circulating autonomously in the community with no link to travel or imported cases. The country recorded 66 new cases in the last six weeks, representing the highest number among European countries.
According to World Health Organization data, Portugal thus became the most affected European country by the new subvariant outbreak. The situation places Portugal in a prominent position in the context of European disease surveillance.
The 1b subvariant has been the subject of international concern since it was identified as one of those responsible for the outbreak that led WHO to declare a public health emergency of international concern. Portuguese health authorities have been monitoring the situation and implementing surveillance and response measures.
The increase in cases in Portugal occurs in a broader context of mpox case growth in Europe, although the situation on the African continent, where the disease is endemic, continues to be the main concern of global health authorities.
