How to prevent the spread of Hantavirus

This is because hantavirus is spread in the urine and droppings of mice and rats. You should wear rubber or plastic gloves when cleaning after signs of rodent infestation appear.

You should spray the droppings with a disinfectant or a mixture of bleach and water. Wet it very much and let it soak for 5 minutes, then wipe it with a paper towel and throw it in the trash. Then seal the trash bag and place it in another trash bag and dispose of it in the regular emptied bin.

Do not sweep or vacuum the mouse. or examining urine, droppings, or nests. This sends viral particles into the air as if they had been breathed.

Ventilate the area at least 30 minutes before work. And make sure to clean the wet area with a disinfectant or chlorine bleach before cleaning.”

Hantaviruses are viruses and are susceptible to most disinfectants. (diluted chlorine solution, detergent, general household disinfectant which includes phenol Quaternary ammonium compounds and hypochlorite) depending on the environment. These viruses may survive less than a week in indoor environments and much shorter periods (hours) when exposed to outdoor sunlight. Special care should be taken when cleaning after rats. In the event that there are many rats It is recommended to consult with a pest control specialist.
