Nizhny Novgorod warns of 'mouse fever' as dacha season begins

Health authorities in Nizhny Novgorod have issued a warning about hemorrhagic fever with renal syndrome (HFRS), often called 'mouse fever'. The alert comes as residents prepare for the dacha season, with rodents posing a heightened risk after overwintering in unoccupied buildings. HFRS spreads primarily through contact with rodents, which frequently nest in summer cottages, sheds, and outbuildings. Mice carry the virus, and humans can become infected by inhaling contaminated dust or direct exposure to rodent waste.

Natalya Sadykova, deputy chief state sanitary doctor for the region, stressed the need for proactive measures. She urged homeowners to inspect and repair buildings, remove waste regularly, and block potential entry points for mice. Preventing infestations is key to lowering infection risks. Before moving into dachas, experts advise a deep clean. Residents should ventilate rooms thoroughly and wipe surfaces with a damp cloth to reduce dust. Wearing masks during cleaning is also recommended to avoid inhaling harmful particles. Symptoms of HFRS require urgent medical care. These include a high fever, intense headaches, sore throat, swollen lymph nodes, and pain in the lower back or joints. Early detection and treatment are critical for recovery.

The warning follows seasonal patterns, as rodents seek shelter in human structures during winter. By maintaining cleanliness and sealing gaps in buildings, dacha owners can lower the chances of HFRS transmission. Authorities continue to monitor the situation while encouraging residents to stay vigilant.
