If you are a North Texas resident, you likely value the peace of your suburban home, the efficiency of your local storage units, and the comfort of your garage or shed. However, as the weather shifts or as we engage in seasonal cleaning, we often come into contact with uninvited guests: rodents. While most of us view mice as a mere nuisance, they can carry a silent and potentially deadly threat known as Hantavirus.
Hantavirus is rare, and its early symptoms resemble many other respiratory illnesses. The CDC notes this makes it difficult to diagnose at first. This guide is designed to help you understand the risks, identify Hantavirus symptoms, and know exactly when to seek life-saving care
What is Hantavirus and How is it Spread in North Texas?
According to the CDC, hantavirus is a family of viruses spread primarily by rodents. In the United States, the most common form is Hantavirus Pulmonary Syndrome (HPS), a severe respiratory disease that can be fatal if not treated urgently. Unlike the common cold, which spreads through human coughing or sneezing, Hantavirus is a “zoonotic” disease, meaning it jumps from animals to humans.
Common Rodent Carriers in the Irving Area
While many rodents live in North Texas, not all carry Hantavirus. According to the NPS, the primary culprit in North America is the Deer Mouse. Other U.S. carriers named by the CDC include the White-footed Mouse, the Cotton Rat, and the rice rat.
You cannot tell if a mouse is carrying the virus just by looking at it. According to the CDC, hantaviruses do not make their rodent hosts visibly ill. Infected rodents still shed virus in saliva, urine, and feces.
Understanding “Aerosolization”: How Humans Get Sick
The most common way people contract the virus is through a process called aerosolization. When rodent urine or droppings are disturbed, such as when you sweep out a dusty garage or move boxes in an attic, tiny droplets containing the virus are kicked up into the air. You can become infected by breathing in the contaminated air, according to the CDC.
Recognizing the Signs: Hantavirus Symptoms vs. The Common Flu
The greatest challenge with Hantavirus is that it begins quietly. Because the initial Hantavirus symptoms can look like a standard viral infection, they are easy to mistake for the flu. The CDC notes that early symptoms are easily confused with influenza.
Early Warning Signs (The Prodromal Phase)
Symptoms usually start to show 1 to 8 weeks after contact with an infected rodent, according to the CDC. Once the “prodromal” phase begins, you may experience:
- Fever and Chills: Fever is one of the early symptoms, and about half of patients also get chills.
- Muscle Aches: Significant pain in the large muscle groups, such as the thighs, hips, and back.
- Fatigue: Feeling very tired.
- Gastrointestinal Distress: About half of HPS patients experience abdominal problems such as nausea, vomiting, or diarrhea.
The Critical Turning Point: When to Seek Emergency Care
About 4 to 10 days after the initial Hantavirus symptoms begin, the late symptoms appear. This is the Emergency Phase, when the lungs can fill with fluid, according to the CDC.
Seek immediate emergency care at the ER if you experience:
- Shortness of Breath: Feeling like you cannot get enough air, even while resting.
- Coughing: A new cough.
- Chest Tightness: A feeling of heavy pressure on your chest.
CDC guidelines emphasize that if you have a history of rodent exposure and develop these symptoms, you must tell your healthcare provider immediately.
2026 Health Update: The Global Andes Virus Outbreak
As of May 2026, the global health community is monitoring a specific strain of Hantavirus known as the Andes virus. While most hantaviruses do not spread from person to person, the Andes virus is a notable exception.
The CDC recently issued a Health Alert regarding a cluster of Andes virus cases linked to a cruise ship in the Atlantic. While this outbreak is currently contained to specific travelers, it highlights the importance of being aware of “atypical” symptoms. Unlike the strains common in Texas, the Andes virus can be transmitted through prolonged close contact with an infected person’s respiratory secretions. If you have recently traveled internationally or have been in close contact with someone who has, please share this information with our triage team upon arrival.
Preventing Hantavirus in Your Irving Home and Property
Prevention is your first line of defense. By making your home less attractive to rodents, you significantly decrease your risk of exposure.
Rodent-Proofing Your Garage, Attic, and Shed
- Seal Entry Points: Mice can fit through a hole the width of a pencil, according to the CDC. Fill small holes with steel wool, and put caulk around it to hold it in place.
- Proper Food Storage: Keep pet food and pantry items in thick plastic or metal containers with tight-fitting lids.
- Clean Up the Yard: Remove woodpiles, tall grass, and clutter from the perimeter of your home where rodents like to nest.
Safe Cleanup: Why You Should Never Sweep Droppings
If you find rodent droppings in your home, do not reach for a broom or vacuum. Sweeping pushes the virus into the air, where you are most likely to inhale it.
According to CDC cleaning protocols, you should:
- Ventilate: Open doors and windows for at least 30 minutes before cleaning.
- Wet it Down: Spray the area with a disinfectant or a mixture of 1 part bleach to 9 parts water. Let it soak for 5 minutes.
- Wipe, Don’t Sweep: Use paper towels to pick up the waste while wearing rubber or plastic gloves.
- Dispose: Seal everything in a plastic bag and place it in a covered trash can.
Don’t Wait, Your Health is Our Priority
If you develop shortness of breath, chest tightness, or a high fever after contact with rodents or their droppings, do not wait. Tell the triage team about the exposure and get emergency care for breathing problems at ER of Irving right away. We are open 24/7.

FAQs
Can my dog or cat catch Hantavirus and give it to me?
No. According to the CDC, dogs and cats are not known to become infected with hantavirus in the United States. However, pets may bring infected rodents into your home.
How long does the virus live in the environment?
According to the CDC, these viruses probably survive less than 1 week indoors. They survive much shorter periods, perhaps hours, in sunlight outdoors.
Is there a vaccine for Hantavirus?
The CDC does not list a vaccine among its prevention steps. It says avoiding rodents and their urine and feces is the best way to prevent infection.
Can I get Hantavirus from a mouse bite?
Yes, but this is rare. The CDC says hantavirus can spread through a rodent bite or scratch.
How do I know if I have the flu or Hantavirus?
While Hantavirus symptoms mirror the flu, the CDC notes that a blood test is often the only way to officially diagnose hantavirus. If you have “flu” symptoms plus shortness of breath after being around rodents, treat it as an emergency.
Does every mouse in Irving have Hantavirus?
No. According to the CDC, about 10% of deer mice tested show evidence of infection, though this varies by place and time. You cannot tell an infected mouse from a healthy one, so clean up all droppings safely.
