Norovirus—the word alone might be enough to make you a little nauseous. The symptoms of norovirus infection in people are downright nasty. Vomiting, diarrhea, fever, headache, and body aches are common and tend to last anywhere from one to three days.
First, some clarification is needed. Dogs and cats appear to have several of their own species of norovirus that cause gastrointestinal symptoms similar to those described above. Why is this important? If it proves to be true, we would know that when dogs in a household become infected with norovirus, people could be at risk for infection, and vice versa. In , a group of researchers in Helsinki, Finland looked at 92 stool samples from dogs living closely with people who had recently experienced symptoms of vomiting and diarrhea.
All NoV [norovirus]-positive dogs lived in households with small children and two dogs showed mild symptoms.
Whether these viruses can replicate in dogs remains unresolved, but an association of pet dogs playing a role in transmission of NoVs that infect humans is obvious. Interestingly, the types of human noroviruses that the dogs had been infected with closely mirrored the types of noroviruses that had been circulating in people in their communities.
In addition, some coronaviruses infect only animals. While the specific source of origin isn't known, the virus that causes COVID is believed to have started in an animal, spread to humans and then spread between people. According to the U. This happened mostly after the animals were in close contact with people infected with the COVID virus. Based on the limited available information, the risk of animals spreading the COVID virus to people is considered low.
There is no evidence that viruses can spread to people or other animals from a pet's skin, fur or hair. However, keep in mind that young children, people with weakened immune systems, and people age 65 and older are more likely to get sick from some other germs that animals can carry. To protect your pet from the COVID virus, don't let your dog or cat interact with people or animals outside your household. For example:.
Instead, contact the veterinarian. He or she might offer advice through a virtual visit or make another plan for treating your pet. Testing is only recommended for pets that have symptoms and have been exposed to a person with COVID If your pet tests positive for the virus that causes COVID , follow the same precautions you would if a family member became infected.
Aim to isolate your pet in a separate room away from the rest of your family and have your pet stay at home. Wear gloves when you interact with your pet or its food, dishes, waste or bedding.
Wash your hands after touching any of your pet's items. However, potentially serious skin infections can occur if the bacteria enter through a break in the skin. Dogs can potentially get MRSA from humans who have the bacteria on their skin. In dogs, MRSA can cause infections of the skin, respiratory tract, and urinary tract.
Tuberculosis is a respiratory illness caused by the bacteria Mycobacterium tuberculosis. In humans, symptoms of an active infection can include coughing, fever, and shortness of breath.
Transmission of tuberculosis from humans to dogs has been reported. In dogs, tuberculosis causes symptoms like cough, weight loss, and vomiting. Bronchitis is the inflammation of the bronchial tubes , which are large airways in your lungs. A person with bronchitis experiences a wet cough, fatigue, and wheezing. In people, viral infections like the common cold or the flu most commonly cause bronchitis.
Canine infectious tracheobronchitis, or kennel cough , leads to symptoms like coughing, sneezing, and fatigue. Kennel cough can occur from the bacteria Bordetella bronchiseptica as well as a variety of canine-specific viruses.
Dogs can pass the infection to each other through direct contact as well as aerosols from coughing and sneezing. Cold sores are fluid-filled blisters that appear on or around your lips.
In humans, a virus called herpes simplex virus HSV causes cold sores. There are two types of HSV. However, one type of herpesvirus is important in dogs. Canine herpesvirus CHV can cause genital lesions and mild respiratory symptoms in adult dogs, and can be serious or potentially fatal in puppies. In addition to the illnesses mentioned above, you can also potentially pass the following infections to your dog.
While most cases are mild, some can be severe and require hospitalization. According to the CDC , an animal that gets the virus may not have any symptoms, or may only have mild symptoms. Currently, the risk of a pet spreading the infection to other people is believed to be low. Ringworm is a fungal infection that affects the skin, hair, or nails.
While ringworm is more typically spread from animals to people, you can also potentially pass it to your dog. Ringworm is spread through contact with the fungus, either by touching the infected area or by coming into contact with a contaminated surface. Dogs that have ringworm can have bald, scaly patches that often appear on their ears, face, or tail.
Older research has found antibodies to the mumps virus in dogs, indicating that the virus can infect them. Mumps cases have declined by 99 percent in the United States due to vaccination.
There are many illnesses you can get from your dog. Rabies can be spread through a bite or scratch from an infected dog and causes a variety of serious neurological symptoms. Ringworm is a fungal disease you can get through contact with an animal that has the infection.
