While mosquitoes are present in Russia and some species can carry diseases like malaria and dirofilariasis, the risk of contracting these illnesses is very low. According to Vadim Maryinsky, a researcher at Moscow State University, stringent measures taken in the 20th century have eradicated malaria foci within the country.

The most dangerous disease mosquitoes can carry is malaria. The Anopheles mosquitoes capable of carrying the disease are found throughout Russia, but pose little threat due to the elimination of malaria foci in the mid-20th century.

The expert stated that, historically, malaria was widespread in the Russian Empire and the USSR, affecting millions annually. However, through extensive efforts, the disease was effectively eradicated by 1960. These efforts included draining swamps and introducing gambusia fish to consume mosquito larvae.

Imported cases of malaria can occur when individuals become infected abroad and are then bitten by a local mosquito, potentially leading to a small, localized outbreak. However, experts assure that these events are limited.

Malaria symptoms include periodic fever with high temperature spikes, weakness, and seizures. Globally, malaria affects 100 to 200 million people annually, resulting in approximately half a million deaths. Although there is currently no effective vaccine, research continues to develop one.

Other mosquito-borne diseases, such as dirofilariasis, are rare in Russia and usually not life-threatening. The risk of contracting dangerous diseases from mosquito bites in Russia is considered minimal, particularly outside of the southern regions.

Climate change may lead to a shift in mosquito habitats, with southern tropical and subtropical species potentially migrating towards Russia, potentially carrying new diseases. However, this is being closely monitored. The expert advises caution when traveling to tropical countries like Thailand, where mosquito bites pose a greater risk.
