Rospotrebnadzor reported on May 12 that over 2.2 million Russian residents received vaccinations against tick-borne viral encephalitis (CVE) during 2026.
The department noted the epidemiological situation for tick-borne infections in Russia remains stable, with the highest number of recorded tick bites occurring in Chelyabinsk, Tver, Omsk, Irkutsk, Moscow, Leningrad, Kostroma, Samara regions, Altai and Krasnodar Territories, the Altai Republic, and St. Petersburg.
At the beginning of the season, more than 43,000 individuals sought medical care for tick bites. Additionally, over 46,000 hectares of territory are currently under preventive measures in areas where large populations gather, including educational and summer health facilities.
Rospotrebnadzor also revealed that Russian ticks can carry viruses beyond encephalitis, such as Badges nayrovarus, Mukava, and Nuomin (also known as Lesnoe).
The World Health Organization provided guidance on tick protection on May 4, recommending light-colored clothing, avoiding tall grass, and staying on open trails when in natural environments.
