Three deer mice collected during routine monitoring in Boulevard have been positive for the potentially fatal hantavirus, County Vector Control said this week. It is generally unlikely that humans will come into contact with hantaviruses if they keep wild rodents away from their homes, sheds, garages and workplaces.
Especially with the start of the spring cleaning season, Vector Control officials urged people to protect themselves. They found wild rodents living in their homes, sheds, and garages.
In particular, officials said that people should remember never to take nail nails or trimmings. Instead, people should use "wet cleaning" methods when cleaning up rodents: wear gloves, spray dead rodents, feces, nests and surrounding areas with bleach solutions, clean with sponges and mops, pack dirt and seal dirt.
Wild rodents, especially mice, are the main carriers of hantavirus. Hantavirus can cause fatal infections in humans, and there is no vaccine or cure.
The likelihood of hantavirus exposure is low, however, as wild rodents usually live in undeveloped areas and usually do not live in the same environment as humans. 1
Avoid exposure to hantavirus
- Close all external holes in houses, garages and sheds larger than one cent to prevent rodents from entering.
- Eliminate rodent infestation immediately.
- Avoid rodent-infested areas and do not rub dust or materials that may be contaminated with rodents and urine.
- Remove rodents and urine using the wet cleaning method described below.
Use "wet cleaning procedure" to prevent inhalation of virus
- Do not sweep or suck areas.
- Affected area by opening doors and windows fo vent at least 30 minutes.
- Use rubber gloves. Spray dead rodents, rodents, nests, contaminated traps and surrounding areas with a 10% bleach solution or other disinfectant and allow the disinfectant to stand for at least 15 minutes before cleaning.
- Clean with a sponge or mop.  Place disinfected rodents and debris in two plastic bags, seal them and discard them with the trash.
- Wash the gloves in a bleach solution, then with soap and water, and dispose of them with the same double bag method.
- Thoroughly Wash your hands with soap and water.
