โ Risk perspective
For most people, the risk of contracting hantavirus is very low. Prevention measures are straightforward and focus primarily on avoiding contact with rodents and their excreta.
Home Measures
Reducing rodent presence in and around the home is the most effective preventive measure. Combine entry-point sealing with eliminating food sources and shelter.
- 1Seal all gaps and cracks larger than 6 mm (mice can enter through very small openings)
- 2Store food (including pet food) in sealed, rodent-proof containers
- 3Keep clutter in storage areas to a minimum โ rodents nest in boxes and old clothing
- 4Empty bins regularly and use tightly sealed bin bags
- 5Remove brush piles, wood stacks and debris from near the house exterior
Outdoor Activities and Camping
Outdoor activities in rural or wilderness areas โ especially in hantavirus-endemic zones โ require additional precautions.
- 1Avoid camping near areas with visible rodent activity (burrows, droppings, gnawed materials)
- 2Sleep on a raised cot or platform, not directly on the ground
- 3Air out tents and sleeping bags before use if stored in outdoor sheds
- 4Keep campsites clean; store all food in sealed containers or hung from trees
- 5Do not disturb rodent nests or burrows โ leave the area if you encounter heavy rodent activity
Cleanup Protocol in Rodent-infested Areas
If you need to clean an area with evidence of rodent activity (droppings, nests, dead animals), follow this step-by-step protocol to minimise the risk of virus aerosolisation:
Ventilate first
Open doors and windows for at least 30 minutes before entering. Do NOT use air-conditioning or fans that could circulate dust.
Wear PPE
Use a correctly-fitted N95 or P100 respirator, disposable gloves, and eye protection. Do not touch your face.
Wet thoroughly
Soak rodent droppings, nesting material and dead rodents with a 1:10 bleach solution (9 parts water, 1 part household bleach) or equivalent disinfectant. Leave for 5 minutes.
Wipe โ never sweep
Use paper towels or damp cloths. NEVER sweep or vacuum dry droppings โ this aerosolises the virus.
Bag and seal
Double-bag all contaminated material in sealed rubbish bags. Dispose of according to local regulations.
Disinfect surfaces
Wipe all surfaces that may have been in contact with rodents using the bleach solution. Mop hard floors.
Wash and decontaminate
Remove PPE carefully, wash hands thoroughly with soap and water, then shower if possible.
Occupational Settings
Workers with the highest risk include farmers, forest rangers, pest control technicians, laboratory staff handling rodents and construction workers in infested buildings. For these groups, additional measures include:
Specific training
Mandatory hantavirus risk training for all workers with potential exposure.
Appropriate PPE
N95 respirator, gloves, disposable coveralls and safety goggles in risk areas.
Health surveillance
Immediate reporting of febrile symptoms after potential exposure to occupational health.
Risk assessment
Prior inspection of buildings or work areas at risk of infestation before starting work.
Is There a Hantavirus Vaccine?
As of 2026, there is no globally approved hantavirus vaccine. China has approved an inactivated vaccine against HFRS strains (Hantaan and Seoul) for domestic use since the 1990s, with limited coverage outside the country. Several vaccine candidates are under research for HPS-causing strains, but none have yet reached international regulatory approval.
Given the global rarity of the disease and the inherent challenges of developing vaccines against multiple divergent strains, hantavirus control continues to rely primarily on preventing rodent exposure.
