Four people in Russia's St. Petersburg city have been hospitalized with confirmed mpox, also known as monkeypox.

The patients’ conditions are assessed as moderate, according to Lenta.ru.

A day earlier, five people were hospitalized in Zhukovsky, a town in the Moscow region, with suspected mpox infections.

The group included three men and two women aged between 22 and 35. Medical assistance was sought after they had contact with a person suspected of carrying the virus.
