In the event of dust or traces of rodents, Hantavirus prevention is based on careful ventilation, wet cleaning, the absence of dry sweeping, wearing a suitable mask, gloves and glasses, disinfection of surfaces and isolation of waste.
Why dry sweeping is a bad reflex
Hantaviruses can be associated with dust contaminated by rodents. The risk increases when these dusts are resuspended and inhaled. This is why defensive cleaning avoids sweeping or dry vacuuming a suspect area.
The logic is simple: ventilate without creating a violent draft, moisten the dust, wear suitable respiratory protection, protect hands and eyes, remove waste in a closed bag and wash your hands after removing gloves.
A heavily infested area, significant quantities of droppings or a sensitive professional premises may require a specialized company.
Organization of clean zone / dirty zone
Before starting, prepare bags, suitable wipes or products, gloves, mask, glasses, spare clothes and the place to remove PPE. The goal is to avoid bringing dust towards handles, vehicles, living rooms or personal objects.
After cleaning, remove the consumables gently, without shaking. Place disposable items in bags. Clean hands and touched surfaces. Wash clothes according to the instructions adapted to the context.
This guide gives a general defensive logic. Medical, professional or highly contaminated situations must be handled by competent actors.
Prepare for cleaning before opening the room
Before you begin, gather materials, choose an exit route, and prevent unprotected people from entering. Impromptu cleaning requires crossing the area several times and increases transfers. If the infestation is significant, if the premises are very closed or if you cannot work without resuspending the dust, call a professional.
Work slowly, without blowing or dry sweeping on suspicious deposits. Humidify according to health recommendations and choose a vacuuming or collection method adapted to the premises, then lock up the waste before leaving the area. Gloves do not replace hand washing and should not be used to touch the phone, clean handle or face.
After the intervention, note the date, location and people exposed. If you develop a fever or unusual symptoms in the following weeks, this information will help the healthcare professional understand the context. Do not attempt to make a diagnosis based on general symptoms alone.
