More than 1,500 people have sought medical attention for mouse fever in several Russian regions, with doctors warning of increased infection risks during the autumn season.

A total of 1,512 cases have been recorded in the Nizhny Novgorod Region, Tatarstan, Bashkortostan, Udmurtia and the Saratov Region, according to SHOT.

The seasonal rise in infections coincides with the autumn migration of rodents, which move from fields closer to residential areas in search of warmth.

People can become infected while clearing fallen leaves at country houses or even in urban areas. Rodents may leave contaminated saliva, droppings and other traces in these locations.

The infection can then spread through the air or through contact with contaminated materials.

Symptoms may include a sudden spike in body temperature to 39-40°C, muscle pain, lower back pain, abdominal discomfort and headaches. Unusual redness may also appear on the face and upper body.

In severe cases, the disease can cause kidney dysfunction, making early medical attention essential.

One of the challenges is that symptoms may not appear until a month after infection. Doctors warn that patients with suspected mouse fever may require hospitalization, as self-treatment can lead to serious kidney complications.

Medical professionals recommend taking precautions when cleaning homes, gardens and surrounding areas where rodents may have been present.

Key safety measures include:

Wear a protective mask when cleaning potentially contaminated areas.

Avoid touching rodent droppings, nests or dead rodents with bare hands.

Wash your hands thoroughly after completing cleaning and other household tasks.

Seek medical attention if symptoms develop after possible exposure to rodents.

There is currently no vaccine against mouse fever available in Russia, doctors warn.

As rodent activity shifts closer to homes during the colder months, health officials advise residents to take extra care when cleaning outdoor spaces, storage areas and country properties.
