Human dirofilariasis is a pressing health problem in Russia. By 2014, there have been as many as 850 Dirofilaria repens-infested people living in 42 subjects of the Russian Federation. One of the favorable factors for circulation and spread of invasion is a temperature of above +20-24 degrees C; when the latter is maintained during at least 20 days there may be 1.-1.5 circulations of invasion in the carrier and a 2.8-fold increase in transmission intensity. The border ofa dirofilariasis area with a temperate climate is southward to 58 degrees N in European Russia and West Siberia and southward to 50 degrees N in the Far East. The conditions in the human body have been found to be more favorable for the development of Dirofilaria than considered before and allow the helminth to achieve sexual maturity and to propagate. If man has microfilaremia, he may be a source of invasion. It is necessary to examine venous blood by the enrichment method and, if possible, polymerase chain reaction and enzyme immunoassay, which make it possible to establish a diagnosis in occult invasion and to identify a pathogen species.
人体盘尾丝虫病在俄罗斯是一个紧迫的健康问题。截至2014年，俄罗斯联邦42个地区共有多达850名感染匐行恶丝虫的人。侵袭传播和扩散的有利因素之一是温度高于+20 - 24摄氏度；当这种温度至少持续20天时，病原体在携带者体内可能循环1 - 1.5次，传播强度增加2.8倍。温带气候的盘尾丝虫病区域边界在俄罗斯欧洲部分和西西伯利亚向南至北纬58度，在远东向南至北纬50度。已发现人体条件比之前认为的更有利于匐行恶丝虫的发育，使该寄生虫能够达到性成熟并繁殖。如果人患有微丝虫血症，他可能成为侵袭源。有必要采用富集法检查静脉血，如有可能，还应进行聚合酶链反应和酶免疫测定，这有助于在隐匿性侵袭中做出诊断并鉴定病原体种类。
