Yes, mouse droppings can be dangerous to health because rodent feces, urine, and saliva may carry bacteria, viruses, and parasites. For hantavirus, the main risk occurs when dried mouse droppings become airborne as dust during cleaning and are inhaled. Therefore, dry sweeping, shaking materials, or vacuuming areas with mouse droppings is not recommended. The area should first be ventilated for at least 30 minutes, then moistened with disinfectant and cleaned carefully. Gloves, a mask, and preferably eye protection should be used during cleaning. Hands should be washed thoroughly with soap and water afterward.
