Fifty-nine cases of dirofilariasis, spread through mosquito bites, were detected in Russia in 2020, according to the Rospotrebnadzor.
In Russia, two types of dirofilariasis are pathogenic for humans – Dirofilaria repens and Dirofilaria immitis. According to statistical reports, only one case of human infection with D. immitis has been registered in Russia. The disease caused by this species, in most cases, is asymptomatic, but in some cases, complaints of chest pain, cough, shortness of breath, fever, chills and malaise are possible.
Human infection with D. repens is accompanied by pain, edema, erythema, and complaints about the movement of the helminth under the skin in about 35% of cases of infection. “This species, in the overwhelming majority of cases, causes human dirofilariasis in our country. The attention of medical and preventive services to this problem is increasing,” the Rospotrebnadzor noted.
The ministry added that dirofilariae are capable of transmitting mosquitoes from the genera Anopheles, Aedes, Culex, Culiseta, Coquillettidia, found in Russia, as well as from some genera living in other countries. More than 60 species of mosquitoes can be potential vectors of D. immitis in the world; for D. repens, their number is several times less.
