CausesHantavirus is caused by a virus. It is transmitted when a person comes into contact with rodents that are infected with the virus or infected rodents' urine or droppings. In the United States, the deer mouse is the rodent most likely to carry hantavirus infection. Hantavirus infection cannot be passed between humans.
Risk FactorsFactors that may increase your chance of hantavirus infection include:
- Living near a forest
- Seeing rodents in your home
- Having rodents present in a work environment
SymptomsHantavirus infection may cause:
- Deep muscle aches
- Severe shortness of breath
DiagnosisYour doctor will ask about your symptoms and medical history. A physical exam will be done.Your doctor may need to test your bodily fluids. This can be done with blood tests. Your doctor may also need pictures of your chest. This can be done with a chest x-ray .
TreatmentThere is no specific treatment for hantavirus infection. Treatment will focus on treating your symptoms, providing breathing support, and making you comfortable.
PreventionThe best way to prevent hantavirus infection is to control rodent infestation in and around your home. This involves sealing rodent entry holes or gaps with steel wool, lath metal, or caulk; trapping rodents using snap traps; and cleaning rodent food sources and nesting sites. In addition, take the following precautions when cleaning rodent-infested areas:
- Wear rubber, latex, vinyl, or nitrile gloves.
- Do not vacuum or sweep the area, since this may cause the virus to get into the air.
- Wet contaminated areas with a bleach solution (such as 1-½ cups bleach in 1 gallon water) or household disinfectant.
- When everything is wet, remove contaminated materials with a damp towel before mopping or sponging the area with the bleach solution or disinfectant.
- Spray dead rodents with disinfectant and double-bag them with all cleaning materials.
- Properly dispose of dead rodents. Contact your health department for disposal methods.
- Disinfect gloves with disinfectant or soap and water before taking them off. Then, thoroughly wash hands with soap and water or a waterless alcohol-based rub (such as hand sanitizer) if soap is not available.
