Hantavirus: What You Need to Know
We understand that news about hantavirus may raise questions and concerns for patients and families. While the current public health risk remains low, awareness and prevention remain important.
Hantavirus is a rare but potentially serious illness primarily linked to exposure to infected rodents and contaminated areas. Health officials continue to monitor recent international cases closely.
What Is Hantavirus?
Hantavirus is a virus spread mainly through contact with infected rodent urine, droppings, saliva, or nesting materials. In some cases, it can cause a severe respiratory illness known as Hantavirus Pulmonary Syndrome (HPS).
Although hantavirus infections are rare in the United States, early recognition and prevention are important.
Why Is Hantavirus in the News?
International health authorities, including the CDC and WHO, are monitoring a recent multi-country hantavirus cluster associated with cruise ship travel involving the Andes strain of hantavirus. Public health agencies continue to state that the overall risk to the general public remains low.
Health officials are coordinating monitoring and response activities, but there is no current indication of widespread community transmission in the United States.
Symptoms May Include
Early symptoms can resemble the flu and may include:
- Fever
- Fatigue
- Muscle aches
- Headache
- Chills
- Nausea or vomiting
- Abdominal pain
As the illness progresses, some individuals may develop:
- Cough
- Chest tightness
- Shortness of breath
- Difficulty breathing
Symptoms may appear anywhere from 1 to 8 weeks after exposure.
Anyone experiencing breathing difficulties after possible rodent exposure should seek medical attention immediately.
How Does Hantavirus Spread?
Most infections occur after breathing in particles contaminated by infected rodent droppings or urine. Infection may also occur if contaminated material enters the eyes, nose, mouth, or broken skin.
Risk may increase when cleaning enclosed or poorly ventilated areas where rodents have been present.
The Andes strain is the only type of hantavirus that is known to spread person-to-person. This spread is usually limited to people who have close contact with the ill person.
Is There a Vaccine or Cure?
Currently, there is no specific cure or vaccine for most hantavirus infections. Treatment focuses on supportive medical care, including oxygen therapy and intensive care support when needed.
There is also no proven scientific evidence supporting ivermectin as a treatment for hantavirus. Healthcare experts continue to recommend evidence based medical evaluation and supportive care.
Prevention Tips
You can reduce your risk by:
- Sealing holes and cracks around homes and buildings
- Keeping food stored in sealed containers
- Removing clutter and rodent nesting areas
- Keeping trash covered
- Using caution when cleaning sheds, garages, attics, or cabins
- Avoiding direct contact with rodent droppings or nests
Safe Cleaning Guidance
Do not sweep or vacuum rodent droppings directly, as this can spread contaminated particles into the air.
Instead:
- Ventilate the area before cleaning
- Wear gloves and preferably an N95 mask
- Spray droppings with disinfectant or diluted bleach
- Allow the solution to soak for at least five minutes
- Wipe materials with paper towels and dispose safely
- Wash hands thoroughly afterward
Public Awareness
Public health experts continue to emphasize that hantavirus remains rare and that the overall risk to the general public is low. Awareness, prevention, and early medical evaluation when symptoms occur remain the best approach.
Since national surveillance began in 1993, fewer than 900 confirmed cases have been reported in the United States.
When to Seek Care
Seek medical attention if you experience:
- Fever and severe muscle aches after rodent exposure
- Persistent cough
- Difficulty breathing
- Chest tightness
- Worsening flu like symptoms
Rapid breathing difficulty should be treated as a medical emergency.
