Do Guinea Pigs Carry Diseases: Diseases That They Can Spread to People and Some Common Cavy Health Problems

Yes, guinea pigs may carry diseases. They are tiny animals, and as such, they are susceptible to various illnesses. Some conditions affecting guinea pigs include respiratory problems, diarrhea, and parasites.

Make sure to keep your guinea pig healthy by providing a healthy and nutritious diet, ensuring that they have plenty of fresh water, and providing them with enough exercise. Consult a veterinarian if you notice changes in your pet’s behavior or appearance.

Diseases That Can Be Spread From Guinea Pigs to People

Guinea pigs are adorable creatures but can also be carriers of diseases that can harm people. These diseases include salmonella and E Coli, which can cause diarrhea and fever in humans.

In addition, guinea pigs may carry other viruses that could prove harmful if contracted by someone else. For example, if you come across an ill guinea pig, you must take them to the vet as soon as possible for treatment. Make sure you keep your pet healthy and free from any illnesses – sick guinea pigs will only spread their disease around more easily!

Health Problems in Guinea Pigs

Ileus or Gastrointestinal Stasis

Guinea pigs can develop several problems with their gastrointestinal system, the most common of which is the ileus. This is when the stomach muscles don’t contract properly, leading to an inability to eat or drink.

Gastrointestinal stasis occurs when the food doesn’t move through the intestine effectively, and in severe cases, this can lead to death.


Guinea pigs are susceptible to many diseases and can quickly develop diarrhea. However, if the diarrhea is severe, it might be necessary to take the guinea pig to the vet for treatment.

Make sure you keep a close eye on your guinea pig and give them the best possible care to prevent any health problems. Make sure they get their water, food, and supplement needs met regularly so that they don’t develop diarrhea in the first place.

Scurvy (Vitamin C Deficiency)

Guinea pigs are particularly susceptible to scurvy, and it is crucial to identify the disease early. Signs of scurvy include poor appetite, a lackluster coat, swollen gums, and red eyes. Vitamin C-rich foods can help prevent scurvy in guinea pigs and should be given as part of their diet.


When it comes to guinea pigs, tumors are a significant concern. These small animals are susceptible to tumors and can even develop cancer. If left untreated, quick-growing tumors can spread and damage your pet’s health – often fatally.

In addition, be on the lookout for symptoms such as persistent weight loss, inability to eat or drink properly, etc. If you catch a tumor early enough, it is usually treatable through surgery or radiation therapy; however, not all cancers are detectable early and may lead to death in some cases unless treated immediately.


Guinea pigs can also get abscesses due to several reasons. Some common causes include diet (particularly wet food), injuries from fights or collisions with other animals, and medical problems like pneumonia or infection.

Abscesses are often painful for guinea pigs and require surgery in some cases. If you see any of these signs on your pet, don’t wait – get them checked out immediately!

Urinary Tract Problems

Numerous urinary tract problems can afflict guinea pigs, and it is vital to be aware of them to prevent them from becoming major issues.

Urinary tract problems are usually easily treatable with antibiotics or surgery, but if left untreated, they can become more serious. Keeping your guinea pig’s environment clean and healthy, you’re helping ensure that their urinary tracts stay functioning correctly!

Reproductive Tract Disease

Reproductive tract disease is a common issue in guinea pigs and can be caused by many factors. To keep your pet healthy and avoid complications, it is crucial to ensure they get all their essential nutrients and enough exercise.

Suppose you notice any of the following signs. In that case, it’s best to take your guinea pig to a veterinarian for treatment: infertility, abnormal urination or diarrhea, and swelling of the reproductive organs.

Ringworm (Skin Fungus)

Ringworm is a skin infection caused by the fungal infection ringworm. This fungus is highly contagious and can be deadly if not treated in time. Common signs of ringworm include redness, swelling, crusting, and hair loss.

You can treat it with topical ointments or oral medication, depending on the severity of your case. Guinea pigs are particularly susceptible to this skin fungus and may develop severe cases if exposed.

Make sure you keep your guinea pig healthy and avoid exposing them to any potential sources of ringworm, such as pet rodents or other animals that have been infected with the disease.

Skin Parasites (Ectoparasites)

Ectoparasites are parasites that live on the skin of guinea pigs. Some parasites, such as lice, mites, and ticks, can cause various problems, from skin irritation to diarrhea and even death in guinea pigs.

It is essential to have regular fecal checks to ensure your pet is free from parasites and receives the proper treatment if needed.

Other Skin Diseases

Guinea pigs are susceptible to many skin diseases, which can be harmful if not treated promptly. Some of the most common ones include mange, scabies, and pyoderma. If you notice any changes in your guinea pig’s behavior or appearance, it is always best to take them to the vet for a check-up.

Dental Disease

Dental disease is a big problem for guinea pigs, as they are susceptible to respiratory infections and can also get many of the same digestive disorders as humans.

To prevent tooth decay and gum disease, it is vital to keep their cage clean and free of bacteria, provide them with a healthy diet, make sure they’re getting dental check-ups on schedule, stop them from chewing things they shouldn’t be chewing on (mainly wood), and exercise them regularly.
