Human dirofilariasis in the Primorye Territory

: Out of 3 species of the nematodes of the genus Dirofilaria recorded in the Primorye Territory, only D. repens was found in human beings. In the past 3 years, there have been 8 cases of human dirofilariasis, of which only one case can be considered to be imported. Mosquitoes are vectors of dirofilariasis. Infestation occurred in the west and south districts of the Territory. The nematodes were most frequently detected first in the eye. Hence they migrated beneath the scalp giving rise to capsules on the cheek, occiput, forehead, or temple. The parasites were extracted only surgically.
