The Borodianka Settlement Council warned of the seasonal rise in risk. Cases peak in the warm months, when people actively clear out cellars, sheds and country houses.

The main source of the virus is rodents, chiefly mouse-like species. The animal itself does not fall ill but sheds the virus in urine, saliva and droppings, and it survives a long time in a dry environment.

The airborne route is the most dangerous

What sets hantavirus apart from many other infections is that you can catch it without ever touching a rodent. The virus enters with dust: when someone sweeps a long-closed cellar, disturbs old hay or shakes out stored items, particles of dried excretions rise into the air.

That is why a dry broom in an enclosed space is the worst possible tool. Dampen surfaces before cleaning, wear a respirator and rubber gloves, and ventilate the space thoroughly.

Symptoms are easily mistaken for flu

The illness begins abruptly: high fever, headache, muscle and lower back pain, later kidney dysfunction. Because the first phase resembles flu, people often treat themselves at home and lose time.

As with leptospirosis, telling the doctor about the exposure is decisive: cleaning a cellar, staying at a country house, handling hay. That detail directly affects whether the correct diagnosis is made.

Prevention comes down to rodent control

There is no vaccine against hantavirus, so the only defence is keeping rodents out of homes and outbuildings. That means sealing gaps, storing grain and animal feed in airtight containers, not leaving food waste in the yard and using mouse control measures in good time.

For the Bucha district, with its private housing, country plots and outbuildings, this is a seasonal and thoroughly practical topic — especially before the autumn clear-out.
