Hantavirus and Andes Virus: Law Enforcement Awareness Brief
Hantaviruses are rare but potentially severe rodent-borne viruses. In the United States, most cases are associated with exposure to infected rodent urine, droppings, saliva, or contaminated dust. Most hantaviruses in the United States do not spread person-to-person.
The major exception is the Andes virus, which has been documented to spread rarely through close, prolonged contact with a symptomatic person. Andes virus spread is usually limited to those with direct physical contact, prolonged time spent in close or enclosed spaces, and exposure to the sick person's body fluids.
Incubation of Andes Virus
The Centers for Disease Control and Prevention lists the Andes virus incubation as 4 to 42 days, median 18 days.
Signs and Symptoms of the Andes Virus
Signs and symptoms of hantavirus appear 4 to 42 days after exposure. Early symptoms of the virus can include:
• fatigue
• fever
• muscle aches, especially in the large muscle groups like the thighs, hips, back, and sometimes shoulders
About half of all patients also experience:
• headaches
• dizziness
• chills
• abdominal problems, like nausea, vomiting, diarrhea, and abdominal pain
Avoid spread of the Andes virus between people by:
• washing hands frequently
• avoiding kissing and sexual contact with someone who may have Andes virus
• avoid sharing drinks, cigarettes, hookah, and vapes with someone who may have Andes virus
• avoid sharing eating utensils or eating food from the same plate or bowl as someone who may have Andes virus
• maintaining distance from someone who may have Andes virus
Protection for Law Enforcement Personnel Managing Andes Virus Patients
The Andes version of the hantavirus requires more precautions in use of personal protective equipment (PPE). When the Andes virus or similar are suspected, use an N95 or higher respirator, gown, gloves, and eye protection.
The Hansen PPE chart has been updated and included below.
Standard Precautions when Managing the Public
Use standard precautions for routine interactions. Consider hantavirus or Andes virus with exposed or infected patients, and upgrade scene safety. Use masks and full PPE early. If a person is suspected to be infected with the Andes virus, notify receiving facility and do not expose emergency medical services or hospital personnel or facilities unless they are protected.
How U.S. Hantavirus Typically Spreads
Hantaviruses that are not the Andes version are found in the United States., and most can cause hantavirus pulmonary syndrome (HPS), a potentially serious disease that can cause damage to the lungs. Non-HPS hantavirus infection can also occur, where patients experience non-specific viral symptoms, but no cardio-pulmonary symptoms. Early symptoms can look like the flu.
Each hantavirus has one primary rodent that carries the disease. The most common hantavirus in the United States is spread by the deer mouse. Cases most often occur in rural areas where forests, fields, and farms offer habitats for rodents. The animals can get into homes and barns, where they may leave urine or feces. Dogs and cats in the United States are not known to become infected with hantavirus, but pets may bring infected rodents to people or into homes.
People can contract hantavirus if they have contact with urine, feces or saliva of a rodent carrying the virus. This can occur when people:
• aerosolize contaminated dust
• breathe in hantavirus-contaminated air when cleaning up after rodents
• touch contaminated objects and then touch their nose, mouth, or eyes
• are bitten or scratched by an infected rodent
• eat food contaminated with hantavirus
Reducing Risk of Hantavirus
The overall risk to the U.S. public and travelers remains extremely low. If you think you had contact with a person with Andes virus and are experiencing symptoms, contact a medical professional or your state or local health department immediately. For those with facility responsibilities, take the following precautions:
• Keep police stations and corrections facilities free of rodents.
• Do not sweep, vacuum, or blow rodent droppings in stations.
• Where droppings are found, ventilate the area well; wet the droppings with disinfectant; and use gloves and respiratory protection when collecting and removing.
Disinfection Practices
Areas and materials exposed to the Andes virus should be disinfected using EPA-registered disinfectant products effective against enveloped viruses, such as products included on EPA List N. This includes Clorox Healthcare Hydrogen Peroxide Cleaner Disinfectant Wipes (EPA Reg. No. 67619-25). These wipes are EPA-registered health care disinfectants and are approved for safe use on law enforcement equipment and vehicles.
Testing for Suspected Hantavirus Illness
Persons who are suspected of having a hantavirus in the United Sates undergo specific testing of blood and other body fluids. Those who have symptoms and a known exposure to the Andes virus are tested in a similar way.
Treatment for Hantavirus Illness
There is no specific antiviral treatment or vaccine for the Andes virus currently available. Symptoms may develop rapidly. Early medical care is critical with care centered on managing symptoms.
Guidance may change as more knowledge of this virus is gained. Consult the CDC, local health departments, and medical personnel for timely updates.

As we head to Fort Worth for the 2026 IACP Technology Conference, one thing is clear: as the Emergency Communications Center evolves, law enforcement gains greater advantages: earlier awareness, richer information, and a stronger foundation for every response.
