What parasites are transmitted from cats to humans

Treatments for rabies

Alas, rabies is an incurable disease. The only salvation can be the rabies vaccine given in the first 72 hours after the bite. In other cases, rabies is detected in cats posthumously.

The main preventive measure is the annual vaccination of the animal.

Disease from cats. Helminthiasis

Helminths or, in common people, worms appear in cats through raw meat or fish (especially river fish). Also, transmission can occur from flies, which pets love to catch. But even if your furry pet does not walk on the street, but eats exclusively dry food, it can also become infected with worms. How exactly? Through your shoes and clothes.

People bring the larvae of worms from the street, without knowing it themselves, the cat becomes infected with the disease.

In the first few days, lichen is difficult to notice, it appears only after a while. Bald spots appear on the cat’s coat with characteristic redness and flaking. Most often, they occur in the ears, paws or tail. Gradually the spots grow all over the body.

This is the case when infections transmitted from cats appear in humans in much the same way.

How worms are transmitted to humans?

Worms can be contracted from cats by hugging, stroking, and kissing them. It’s no secret that cats actively lick all parts of the body, because the larvae of worms can be distributed throughout the coat. For this reason, do not forget to wash your hands, especially before eating.

How rabies is transmitted to humans from cats?

An infected animal can bite a person and then the disease is transmitted to him (through saliva).

How to avoid infection with worms?

Feeding the cat with anthelmintic drugs is considered a good prevention. If she walks down the street, then once every 3 months, and if not, then once every six months. It is also better to exclude raw fish and meat from the animal’s diet.

Diseases of cats transmitted to humans

The list of ailments that a pet can “reward” with is extensive, but not all of them, and not always transmitted to humans. Sometimes this requires special conditions (like epidemics and others), so it makes sense to take note of only the most common.

How pets transmit diseases to humans

Tuberculosis

Cats with tuberculosis are quite rare. Mostly cattle are sick with it, but there are exceptions.

A pet can become infected with tuberculosis through contact with sick animals, their secretions, as well as through unpasteurized cow’s milk.

First of all, the cat has diarrhea, vomiting, lack of appetite and weight loss. Later, non-healing wounds (ulcers) appear, and as the disease progresses, coughing occurs. The animal begins to breathe heavily and wheeze, make barking sounds.

The probability of transmission of the disease from cats to humans is low, but by no means zero. Therefore, most often it is not recommended to treat animals with this disease. Euthanasia is the most common solution to the problem.

Hookworm

These worms have the shape of a hook and are about 1.5-2 cm long, found in areas with hot climates. They enter the host’s body either with food, or the larvae are introduced through the skin, and then penetrate into the bloodstream. Adults feed on red blood cells, therefore they quickly lead to the development of anemia in animals and humans. Children are most vulnerable to the disease, who can get worms through the mouth with food and water or through the skin. The incubation period lasts about 2 months, after which symptoms of anemia, indigestion, allergic reactions appear, exacerbation of chronic diseases occurs, in severe cases the central nervous system is affected. Hookworms can carry anthrax and tuberculosis pathogens. Diagnostics is carried out by analyzes of feces and blood, treatment is prescribed by a doctor on an outpatient basis or in a hospital.

Here are some tips:

Keep the tray away from the kitchen or other areas where you prepare or store food. Clean it daily and try not to inhale filler dust or sand. Always use disposable gloves when cleaning the tray.

In addition, it is very important that you monitor your cat regularly so as not to miss the first signs of illness.

What can you catch from cats

Although most feline infectious diseases only affect cats, some of these diseases can be transmitted from cats to humans. Let’s take a look at the most common diseases that cats carry. In this material, you can familiarize yourself with simple preventive measures, following which, we can reduce the risk of infection.

People with immature or weakened immune systems are more susceptible to these diseases.

  • babies,
  • people with acquired immunodeficiency syndrome (AIDS),
  • elderly people,
  • people with cancer undergoing chemotherapy,
  • people taking other drugs that can suppress the immune system.

The disease develops as a result of ingestion of the pathogen (Bartonella henselae), which is a representative of the normal microflora of the oral cavity of cats. The bacterium enters the human body through close contact with a cat (licking, scratching, biting, etc.). The disease is characterized by the appearance of a raised spot with a red rim, at the site of an already healed scratch. After 2-3 days, it turns into a bubble filled with cloudy contents. A sore or crust forms at the site of the bubble. A few days (maximum 1.5 months) after the scratch is applied, an increase in the lymph node nearest to it occurs. Those affected may experience fever, headache, muscle and joint pain, fatigue, and poor appetite. Healthy adults usually recover quickly enough, but it can take several months for the disease to completely clear up. People with compromised immune systems can develop complications such as infections of the eyes, brain, and heart.

Most often, pasteurellosis occurs after bites, scratching by cats. Clinical forms of the disease can be divided into 3 groups:

  • cutaneous. swelling, soreness, suppuration (phlegmon);
  • pulmonary. the disease proceeds as chronic bronchitis, sometimes with the development of bronchiectasis or in the form of sluggish interstitial pneumonia;
  • septic. is especially difficult, accompanied by high fever, with the occurrence of complications such as endocarditis, brain abscesses, purulent meningitis, purulent arthritis, etc., the development of infectious-toxic shock is possible.

Salmonella is more common in cats that eat raw meat or wild birds and animals. Human infection can occur while cleaning the litter box. The pathogen is excreted in the faeces of infected cats. The most common symptoms in a person are diarrhea, fever, and stomach pain.

Fleas are the most common external parasite in cats, and their bites can cause itching and inflammation in humans and cats. Fleas are carriers of tapeworm eggs. During the biting and swallowing of fleas, helminth eggs enter the digestive tract and further into the intestines of the cat, where parasites begin to multiply.

Scabies is an infection caused by the mite Sarcoptes scabiei. is another zoonotic external parasite of feline skin. Scabies mites can be transmitted from infected cats to humans.

The characteristic signs of the disease are itching and papulovesicular rash, often with the addition of secondary pustular elements due to infection during scratching. Several feline intestinal parasites, including roundworms (Toxocara) and hookworms (Ancylostoma). can also cause disease in humans. Children are especially at risk due to their greater likelihood of contact with soil that has been contaminated with cat feces. Although most people infected with feline intestinal parasites show no signs of illness, some people can get sick.

Toxocariasis (toxocariasis), characterized by fever, bronchitis, pneumonia, enlarged liver, spleen, eosinophilia.

Ankylostomiasis, or earthen scabies. helminthiasis, occurring with allergic lesions of the skin, respiratory organs (at an early stage), gastrointestinal tract and iron deficiency anemia (at a later stage).

Prevention measures.

Keep your kitten in the house. This is the best way to prevent your cat from contracting zoonotic diseases. Follow your veterinarian’s recommendations for vaccinations, parasite testing, treatment and prevention.

Since many of the diseases listed above are transmitted through contact with feline faeces, several measures can be taken, and most of them involve simple hygiene and common sense. In all cases, you should avoid direct contact with cat feces.

Ringworm.

Ringworm is a skin disorder caused by a fungus. It is also known as dermatophytosis. Ringworm is an infection in the dead layer of skin, hair and nails. It can easily be transmitted from pets to humans. Children are very susceptible to this infection.

Ringworm can be caused by several types of fungi, and they usually get their name from their location on the body, such as the legs of an athlete. Trichophyton and Epidermophyton are fungi that can grow in warm, moist areas of the body, such as the groin or between the toes.

The most common sign of ringworm is a painful rash. Sometimes the rash is flaky and even blisters can form. Ringworm usually appears on the legs, groin, scalp, and nails. There is also a form called body ringworm that can develop anywhere.

Most of these infections can be treated with antifungal creams. It is important to follow the instructions carefully, as they may be repeated if the treatment is over too early. Decontamination and drying of infected areas is essential. It is also important to treat cats and dogs.

3 salmonella.

The bacterium Salmonella is found in the intestines and faeces of humans and animals, and in many foods, especially raw meat. Salmonella can cause food poisoning, the symptoms of which are diarrhea and vomiting.

People can become infected with salmonella through direct contact with their pets or their feces. It is important to wash your hands well with soap and water after touching pets or cleaning their toilet.

Symptoms of salmonella poisoning include headache, fever, diarrhea, and abdominal cramps. The symptoms of the disease disappear on their own and do not require special treatment. Children and the elderly, as well as patients with reduced immunity, require qualified medical care.

To avoid catching Salmonella from cats, it is advised to be careful when handling feces in trays. It is better to wear gloves and be sure to wash your hands.

Toxoplasmosis.

Toxoplasmosis is an infection caused by a single-celled parasite, toxoplasma gondi, which can only reproduce in the cells that line the intestines of cats. Although most pets can transmit the disease, only cats shed eggs that cause this infection.

Cats become infected with this infection by eating rodents or insects or by contact with other infected cats or their feces.

Toxoplasmosis is spread to humans when they do not wash their hands after contact with cat feces, while working in the garden, or cleaning cat trays. Children can pick up the pathogen by playing in the sandboxes. It can also be transmitted by eating unwashed fruits and vegetables grown in soil contaminated with cat feces.

Eating raw or undercooked meat can also “deliver” the parasite into the body.

Toxoplasmosis is most dangerous for a pregnant woman who can transmit this infection to her fetus through the placenta. It can lead to miscarriage or the birth of a child with congenital toxoplasmosis, which is dangerous for the life of the baby. If the child survives, he may suffer from blindness, jaundice, seizures and severe mental retardation.

In infants, mild symptoms may appear soon after birth, but most often years later. Symptoms vary depending on the type of toxoplasmosis the person has been infected with.

Possible symptoms include fever, a general feeling of malaise, and swollen lymph nodes. If a person’s immune system has been compromised in some way (such as AIDS diagnosed), toxoplasmosis can cause life-threatening brain infections.

The presence of antibodies against the parasite can be determined with a blood test. This is the most commonly used method to determine if a person is infected with toxoplasmosis. In the case of immunocompromised patients, the physician may choose computed tomography with CT or MRI to make a diagnosis.

In general, the prognosis for people who acquired toxoplasmosis after birth is favorable. Most people who have a well-functioning immune system do not need treatment and the disease goes away on its own. There are special medications for pregnant women or people with weakened immune systems.

There is no vaccine against toxoplasmosis, and prevention is to reduce the risk of meeting the parasite. Pregnant women should not mess with cat litter. Other people should only clean sandpits with plastic gloves and then wash their hands with hot water and disinfectant soap.

Children’s sandpits must be covered. The vegetables should be washed properly. After processing raw meat, hands are thoroughly washed, and the meat itself must be thoroughly fried. Gloves should be worn when gardening and hands should be washed with soap.

Bartonellosis of cats.

Bartonellosis is caused by several bacteria in the Bartonella family. A specific microorganism that is transmitted from cats to humans through bites or scratches is called Bartonella henselae. Therefore, bartonellosis is commonly referred to as “feline disease” or “cat scratch fever.”.

This infection is often carried by kittens, whose claws are especially sharp. This type of bacteria infects the walls of blood vessels in humans, while cats have no symptoms.

A red bubble appears near the scratch, sometimes up to 4 cm in diameter. Enlarged lymph nodes, fever, and headaches are noted. Also, some patients experienced a decrease in appetite.

For most people, these symptoms go away, but this can take two to five months. A blood test can detect antibodies against the bacteria that cause this infection. Analgesics, lymph node drainage, and sometimes antibiotics are all ways to combat this condition. Most people make a complete recovery.

The easiest preventive measure is to prevent the cat from scratching itself. House cats should have their nails trimmed. If the cat does scratch, it is recommended to immediately wash the affected area with hot water and soap / disinfectant.

Than helminthic invasions can threaten

  • Infection with worms is not just an unpleasant process, but also a serious disease. Since worms are parasitic organisms, they live and feed on the host. And they throw out numerous waste products into his body, which cause various reactions of the body. from allergies to damage to the central nervous system.
  • Against the background of mass destruction of the body by worms, intestinal blockage, the development of autoimmune diseases, damage to the brain, liver, joints, lungs and other organs can occur. Not to mention cough, nausea, vomiting, headaches, allergic dermatitis and other body reactions to poisoning by the waste products of helminths.
  • This parasitic mechanism has been developed over millennia of evolution. At the moment, some types of worms do not even have an oral cavity. they live by absorbing nutrients from the surface of the body. The number of species is enormous. It’s easier to say where worms cannot parasitize in the human body. these are hair and nails.
  • At the same time, the mechanism of reproduction and distribution of worms has been worked out with amazing clarity. we can say with confidence that worms will never disappear from the planet. One individual of a flat tapeworm is capable of producing more than a million eggs in a lifetime, which are covered with a dense shell and are able to outlast the most unfavorable conditions for decades.
  • Carriers of helminth eggs can be wind and dust, animals and insects, food, water and other factors, including favorite pets. cats.

Giardia

Giardiasis in cats is also widespread. And to a person in contact with a pet, lamblia can be transmitted. It is more difficult to define this disease than helminthiasis. It is most often asymptomatic, but parasites disrupt digestion.

If your pet loses weight, while eating normally, and its excrement looks abnormal, it is worth checking it for giardiasis.

Diarrhea can occur in young cats with this disease, but this does not always happen, which makes the symptoms of the disease not obvious at first glance.

It is imperative to treat an animal for giardiasis, even if the parasites do not negatively affect its health in any way. Yes, it happens. But in order to prevent human infection, it is necessary to carry out treatment.

Everything is complicated by the difficulty in diagnosis. It will take several times to test the cat’s feces for the tests to be considered accurate.

Giardia perfectly hide in the host’s body, preventing themselves from being detected the first time.

There is a possibility that the treatment will need to be carried out more than once. Giardia in the intestinal area may not be eradicated immediately. During the period of therapy for the animal, it is also necessary for a person to be checked in order to exclude a possible infection. And if you managed to catch parasites, do not postpone your own disposal of them.

Your cat can catch Giardia through drinking water. Just like you. The special danger of giardiasis is that it can be transmitted from the person himself to the animals. Therefore, you should not drink raw tap water, even if you really want to.

The most common parasitic bacteria in cats are Toxoplasma and Salmonella. Transmitted to humans by contact. Cause toxoplasmosis and salmonellosis.

Toxoplasma lives and actively reproduces in the cat’s intestines. In the fields, where there is a lot of litter of street and wild cats, animals feed on grass. Bacteria enter their body, and then end up in the resulting meat.

You buy this meat, nip off a piece to the cat, which looks with such hungry eyes that it is difficult to resist. And you get an infected animal, the bacteria from which will probably pass on to you.

Toxoplasma is especially scary for pregnant women.

Pregnant cat owners are not advised to clean up after their pets. And if there is no one else to shift this responsibility to anyone, you must use gloves and be sure to wash your hands after cleaning.

Toxoplasmosis in cats themselves usually resolves without symptoms. In humans, it looks more like a cold. For a person who does not carry a fetus in himself, it is practically not dangerous and passes without complications.

But the fetus can significantly harm.

Salmonella is also spread through raw meat. It is much easier to define it, because it proceeds in an unpleasant way for a pet. With timely treatment, both the person and the cat will not have any complications in the future.

Giardia in cats

Giardia is a type of intestinal parasite that is indicated by a symptom such as diarrhea. According to statistics, they are present in the body of 6% of cats. It is this type of parasite that is contagious. It is noticed that the risk of infection with lamblia increases with a large number of pets, especially kittens, whose immune system has not been fully formed.

The main preventive measure is the regular examination of the cat. In addition, to prevent disease, you need to clean the tray daily, wash the cat bowls for food and water with soap and water, and wash towels and blankets, which most often the animal is on. In the case of parasites, it is necessary to limit communication with the cat and immediately undergo a course of treatment.

How to avoid infection?

It is not worth getting rid of the cat and keeping the child out of it for fear of getting sick. First, because the number of zoonoses is not large. Secondly, adherence to a few simple rules will help to avoid infection when communicating with a pet.

First of all, you need to change the cat’s litter box in a timely manner, while using special disinfectants. As for the feeding of the cat, it must be of high quality. In addition, it is worth forbidding your pet to hunt rodents. It is rats and mice that are the main carriers of dangerous diseases.

An important point in the prevention of invasions is a regular examination by a veterinarian and the presence of all vaccines.

What types of parasites can be infected from a cat

All of the above does not mean that a domestic cat is not capable of becoming source of human infection. Officially, it is the source of diseases called giardiasis and toxoplasmosis. these are the simplest parasites that can cause the most unpleasant consequences in humans. Our list doesn’t end there.

Pet owners should be aware of which worms are transmitted from cat to person and how they do it:

  • Roundworms are roundworms, their eggs enter the environment with feces, and from there a walking cat can bring them into the house on its fur. By stroking it and not washing your hands, you bring the parasite into your mouth, where its development cycle begins.
  • Echinococcus. This is a rare helminthic invasion. Usually, such worms affect large predators, wolves or dogs that eat raw meat infected with echinococcus larvae. A cat can become infected by eating raw meat and becoming the host of an adult parasite that secretes eggs. These worms in cats are transmitted to humans with the help of eggs, which will be enough in the tray and on the animal’s fur.
  • Enterobiasis. This common type of so-called “children’s” worms, most often comes across in the soil. A cat can bring eggs pinworms after walking on wool and on paws.

In theory, an animal can bring eggs of any parasite into the house, which a person can swallow. Another thing is that the human body is not suitable for all worms as a host.

Are worms transmitted from cats to humans? Types of cat parasites

According to statistics, more than 4 billion people on Earth are infected with various helminthic diseases. Such a scale of the spread of helminths makes you think about precautions. Even a favorite pet, a cat, can become source of helminthic invasion in a domestic environment.

Seeing an unpleasant surprise in the tray, the owner wonders: can a person get infected with worms from a cat and are cat worms dangerous for humans??

Cat scratches and bites

Scratches and bites are often the result of simple play with your pet. In this case, there is no need to worry. However, if a stray cat has left a mark on the skin, then you should consult a doctor. The same should be done if the hand is swollen after a scratch or bite.

It is necessary to resort to the help of a specialist if the animal shows unnatural aggression and bites for no reason. These symptoms indicate the presence of rabies in the animal. If a person becomes infected with rabies, an urgent need to undergo appropriate treatment.

For a cat, this disease means death, but its owner can be helped with timely diagnosis. over, if possible, an animal should also be taken to the hospital for testing.

Is there a chance of getting infected?

It is believed that any worms in cats are transmitted to humans. In fact, some cat worms are really infectious for humans, however, not all.

For example, hookworms, which are often detected in a kitten and pose a serious danger to him, cannot pass from a cat to a person.
