Two recent cases of hantavirus pulmonary syndrome were confirmed in residents of the Texas Panhandle and South Plains, bringing the year’s total to three.

Texas had one case in 2013. No cases were reported from 2009 to 2012.

The disease is severe and sometimes fatal, prompting the Texas Department ofState Health Services to remind people to protect themselves from the virusthat causes HPS. A case confirmed earlier this year was a resident of thePanhandle.

Hantavirus is carried by certain species of rats and mice that shed the virusin their urine, droppings and saliva. The virus can be transmitted to peoplewhen nesting materials or dust contaminated by infected rat or mouse urine,droppings and saliva are stirred up, allowing the virus to be breathed in byhumans. The illness is rare, but HPS cases are frequently associated withspring cleaning.

DSHS recommends general safety precautions that apply to Hantavirus as well asother infectious diseases:

  • Seal openings that may allow rats and mice to enter homes and workplaces.
  • Remove brush, woodpiles, trash and other items that may attract rats and mice.
  • Tightly close garbage cans, pet food containers and other food sources.
  • Before cleaning up nests or droppings found inside, open windows and doors to ventilate the area for at least 30 minutes.
  • If any dust will be stirred up, goggles and a HEPA or N-95 mask are recommended.
  • Wear protective gloves to handle dead mice and rats or to clean up nesting areas, urine or droppings.
  • Do not stir up dust by sweeping or vacuuming. Dampen areas before cleanup with either a 1-to-10 bleach-water mixture or another effective disinfectant, in order to eliminate dust and begin inactivating the virus. After 30 minutes, apply the viricide again and immediately begin the cleaning process.
  • Use the same viricide and apply to dead rodents, nests, urine and droppings before cleaning, with the same 30 minute interval and reapplication process.

Early symptoms of hantavirus infection include fatigue,fever and muscle aches. These symptoms may be accompanied by headaches,dizziness, chills, nausea, vomiting, diarrhea and abdominal pain. Latersymptoms include coughing and shortness of breath. If hantavirus is suspected,people should contact their health care provider immediately and inform thepractitioner of exposure to rodents, their waste, or their nesting material.

A total of 41 HPS cases have been confirmed in Texas since 1993, the first yearit was reported. 14 of those cases resulted in death.
