April 27, 2025 – Mariposa County Health & Human Services officials announce Hantavirus Pulmonary Syndrome is a rare but potentially life-threatening viral illness transmitted to humans from the infected urine, droppings or saliva of certain species of mice and rats.

Before cleaning an area infested by mice, air out the space for 30 minutes. Then use a mop or sponge and a freshly made 10% bleach solution to clean the area. Wear gloves while cleaning, and consider wearing a respirator (face mask) if cleaning heavily infested areas.
