This study was performed to determine the yearly frequency, trends in spread, and clinical-epidemiological characteristics of human subcutaneous/ocular dirofilariasis (HSOD) in the Russian Federation and Belarus. The surveillance data of HSOD was done between January 1997 and June 2013. The spatial distribution of cases was assessed using a GIS map, and the clinical-epidemiological characteristics were also defined.
One thousand two hundred and seventy-two clinical cases of HSOD were identified, the majority of them reported in the south-western regions of the Russian Federation. The disease has spread into northern areas, changing its limit from latitude 45°N in 1997 to latitude 61°N in 2013. The statistical analysis of the data showed that the disease is more frequent in the ocular location, in women, in patients aged between 41 and 60 years, and in patients living in urban areas.
