Can Cats and Dogs Get Hantavirus? Symptoms and Precautions

The recent passing of Betsy Arakawa, wife of actor Gene Hackman, due to hantavirus, has elevated the dangerous disease into the national spotlight, causing many to assess their own risk factors and take preventative measures.

Naturally, this has left pet owners wondering whether their cats and dogs can get hantavirus too?

Here’s what you need to know:

What is Hantavirus Pulmonary Syndrome (HPS)?

Hantavirus Pulmonary Syndrome is an extremely dangerous respiratory disease contracted through direct exposure to contaminated rodent droppings, urine, and saliva. Early symptoms resemble the flu, including fever, headaches, muscle aches, and nausea. As the disease progresses, fluid begins to fill the lungs, causing tightness and severe shortness of breath

There is no known cure for HPS. Those who reach the stage of respiratory distress are in grave danger. According to the CDC, 35 percent of hantavirus infections have resulted in death.

The disease is far more common west of the Mississippi in the Four Corners region (Arizona, New Mexico, Colorado, and Utah), but can be found most anywhere in the United States.

Can Cats and Dogs Get Hantavirus?

Yes, cats and dogs are believed to be able to carry hantavirus. But because neither are known to express symptoms of the virus, it is difficult to detect.

A 1994 study found that five percent of outdoor cats carried antibodies for the virus, providing evidence of their susceptibility.

Can Cats and Dogs Transmit Hantavirus to Humans?

There is no evidence that cats or dogs are able to transmit the virus to their owners. Hantavirus is only transmitted to humans through rodents — most often the deer mouse, the white-footed mouse, the rice rat, and cotton rat.

That said, it is possible for cats or dogs to increase the risk of transmission to humans by brining rodents into closer proximity of their owners. If your outdoor pet is prone to killing mice or rats, make sure you always handle the remains with great care. Even sweeping up rodent debris can cause the virus to be inhaled through air particles. Mask up and wear gloves.

Should You be Concerned if Your Pet Eats a Rodent?

Even if the risk of hantavirus is small, there are other rodent-transmitted diseases to be aware of, from tapeworm to Rat-Bite Fever and leptospirosis. While symptoms are still likely to be minimal in cats, dogs can become quite ill. If you notice your pet displaying any of the following symptoms, take them to a vet:

• Fever
• Lethargy
• Loss of appetite
• Difficulty breathing
• Vomiting or diarrhea

Take Preventative Measures to Rodent-Proof Your Home

Whether it concern your pets or yourself, it is always a good idea to keep rodents away from your home. If you’ve had signs of a rodent infestation, take preventative measures:

• Seal entry points with caulk or steel wool.
• Remove food and water sources that attract rodents.
• Secure trash and food storage areas.
• Install a Box-Kat mouse barrier to prevent rodent access.

If there are active rodents in the area, use mice traps or bait stations to remove them and thoroughly disinfect afterwards. A bleach solution (1.5 cups bleach to a gallon of water) is an effective tool. And always remember to avoid handling rodent debris without gloves and a mask.
