Hemorrhagic Fever with Renal Syndrome Established in Saratov, Russia

in Infectious Diseases/Outbreak Watch by

According to a (translated) report in Free News Volga, the Saratov regions remains active for the transmission of Hemorrhagic Fever with Renal Syndrome (HFRS). In January 2015, as many as 121 people were identified to be suffering from HFRS, which represents a four fold increment to the number of cases reported in January 2014.

HFRS is a group of symptomatologically similar diseases caused by a group of viruses belonging to the family Bunyaviridae. The viruses that cause HFRS include Hantaan, Dobrava, Saaremaa, Seoul and Puumala viruses.

These viruses are primarily carried by rodents and human beings get affected when they come in contact with rodent urine or saliva or even aerosolized dust from rodent nests. Known carriers

include the striped field mouse (Apodemus agrarius), the reservoir for both the Saaremaa and Hantaan virus; the brown or Norway rat (Rattus norvegicus), the reservoir for Seoul virus; the bank vole (Clethrionomys glareolus), the reservoir for Puumala virus; and the yellow-necked field mouse (Apodemus flavicollis), which carries the Dobrava virus.
Control measures, therefore, center around measures for rodent control and exposure limitation. None of the HFRS have a specific treatment and supportive therapy, with maintenance of hydration, electrolytes, appropriate antibiotics to treat any secondary infections and dialysis for renal support being the pillars of disease management. Depending on the causative virus and the patient profile, mortality varies from as low as 1% to as high as 15%.
