Kingman-area hantavirus death prompts Mohave County rodent-safety warning

Mohave County Public Health is warning residents after confirming a death from Sin Nombre hantavirus in the Kingman service area. County officials said this is the county’s first confirmed death tied to the strain, and the source of exposure could not be determined. Local transmission cannot be ruled out.

The county said Sin Nombre virus is carried primarily by deer mice and is not known to spread from person to person. The warning is aimed at people who may be opening or cleaning enclosed spaces where rodents can live or leave droppings behind.

Why the warning matters now

That includes homes, sheds, garages, barns, cabins, campers and RVs, storage areas, vacant buildings, and other seasonal or cluttered spaces that have been closed up for a while.

Arizona health officials say hantavirus risk rises when rodent droppings, urine, saliva, or nesting materials are disturbed in poorly ventilated areas. The problem is not limited to obvious infestations. Even a space that looks dormant can hold contaminated dust if deer mice or other rodents have been there.

What residents should do before cleaning

Public health guidance from Mohave County, the Arizona Department of Health Services, and the CDC all points to the same basic precautions: do not sweep or vacuum rodent droppings, because that can stir contaminated dust into the air.

Instead, open doors and windows and let enclosed areas air out before cleaning. Wet droppings or nesting material with a disinfectant or bleach solution and let it soak before removal. Wear gloves and a well-fitting mask, use disposable materials to pick up contaminated waste, and seal it in plastic bags before disposal. Wash hands thoroughly when finished.

Officials also advise residents to reduce rodent access over time by sealing gaps around structures, removing brush and wood piles near buildings, and storing food, pet food, and garbage in rodent-resistant containers.

Symptoms to watch for

Anyone with possible exposure who later develops fever, fatigue, muscle aches, headache, nausea, vomiting, diarrhea, cough, or shortness of breath should seek medical care and tell a provider about the rodent exposure. Health officials say early attention matters because hantavirus can become serious quickly.

For Kingman-area residents, the practical takeaway is simple: take extra care before cleaning out sheds, garages, trailers, and other closed-up spaces. If the area has visible droppings or nesting material and feels unsafe to clean, county officials say it is reasonable to call a licensed pest control or remediation professional instead of handling it dry and unprotected.
