Hantavirus: Prevention, Symptoms & Treatment

"Be wise in preparation and faithful in stewardship of health.”

What Is Hantavirus?

Hantavirus is a rare but serious viral infection transmitted primarily through contact with infected rodents, especially deer mice. Infection can occur when people inhale airborne particles contaminated with rodent urine, droppings, or saliva—often while cleaning enclosed spaces such as cabins, sheds, basements, or garages.

Common Symptoms

Symptoms may appear 1–8 weeks after exposure and often begin like the flu:

  • Fever and chills
  • Severe fatigue
  • Muscle aches
  • Headache
  • Nausea, vomiting, or abdominal pain
  • Dizziness

As the illness worsens, breathing problems can develop:

  • Shortness of breath
  • Dry cough
  • Chest tightness

Treatment

There is currently no specific antiviral cure for hantavirus. Early medical care is extremely important.

Treatment focuses on supportive care, including:

  • Oxygen therapy for breathing difficulty
  • IV fluids and close monitoring
  • Intensive care support in severe cases
  • Mechanical ventilation if respiratory failure develops

Early recognition and prompt hospitalization can improve outcomes.

Prevention Tips

Avoid Sweeping or Vacuuming Rodent Droppings

Sweeping can release infected particles into the air.

Safe Cleanup Steps

  • Air out enclosed spaces for at least 30 minutes.
  • Wear gloves and a mask if available.
  • Spray droppings and nesting areas with disinfectant or bleach solution.
  • Allow the area to soak for 5 minutes before wiping clean.
  • Dispose of waste in sealed bags and wash hands thoroughly.

Reduce Rodent Exposure

  • Seal holes and cracks in buildings
  • Store food in rodent-proof containers
  • Remove clutter and nesting areas
  • Keep homes and campsites clean

When to Seek Medical Attention

Seek immediate medical care if flu-like symptoms develop after rodent exposure, especially if accompanied by shortness of breath or chest tightness.

Important Reminder

Hantavirus is rare, but awareness and prevention are important—especially during spring cleaning, camping season, and work in closed or dusty spaces.

“Health is a gift from God, and prevention is one of our greatest tools of stewardship.”
