Mpox (monkeypox) has been detected in Russia in a Moscow region resident who was hospitalized in the Domodedovo hospital.

“The patient’s condition is satisfactory, he is receiving symptomatic treatment,” the press service of this medical institution reported.

Rospotrebnadzor—the Russian Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing—is conducting an epidemiological investigation to identify the source of this infection and those who came into contact with the patient.

The patient was taken to the hospital the day before yesterday after running a fever of 40°C. Before that, he was treated at home with an ointment against herpes, thinking that he had a cold. The patient assures that he did not travel abroad and did not visit public baths. The source of infection is unknown to him.

According to the Baza and Mash Telegram accounts, mpox is also suspected in another resident of the Moscow region. And this person has concomitant diseases: HIV and syphilis.

Mpox is a viral disease that is accompanied by high fever, enlarged lymph nodes, and a skin rash. It is transmitted through close contact with an infected animal or person through biological fluids or contaminated objects.

The disease is most common in remote areas of Central and West Africa. However, in 2022-2023 it spread to European countries. The outbreak was mainly associated with the LGBT community; the virus is transmitted sexually.

The last major outbreak of mpox began in 2024 in the Democratic Republic of the Congo, as a result of which more than 80,000 people fell ill and 1,300 died. A state of emergency was declared in the region to combat the spread of the infection, and it was lifted only in late January 2026.
