What s the deal with cat scratch disease? Why do you have lumps on your body after petting cats?

People who love to have kittens are at risk of infection.

Cat-scratch disease, also known as cat-scratch lymphadenitis, is an infectious condition. "Cat-scratch disease is a condition caused by Bartonella bacteria, which are mainly present in cats and are generally not easy to cause cats to get sick. However, after a person is scratched or bitten by a cat, this kind of germ is likely to enter the body from the wound and cause infection with cat-scratch disease. Flea bites from cats are also very likely to be infected with cat-scratch disease; Cats infected with this type of disease can also be infected with cat-scratch disease if they lick their wounds or both eyes.

Li Tong, deputy senior professional title of the Department of Infectious Diseases of Beijing You'an Hospital Affiliated to Capital Medical University, once said.

In 2015, the Chinese Journal of Vector Biology and Control published a clinical epidemiological data survey report in Beijing, and the detection rate of Bartonella seroserum in cats was as follows. With the increasing number of small pets such as cats, cat-scratch disease is gradually increasing.

Li Tong once said that according to reference reports, there have been cases of cat-scratch disease in at least a dozen provinces in China. According to news reports, more than 40,000 cases of cat-scratch disease are reported each year around the world, and the CDC may have 10,000 cases of cat-scratch disease in the United States every year, of which about 500 people need to be hospitalized. Li Tong once stated:

Because of the lack of specific diseases, the vast majority of designated medical institutions also lack corresponding testing methods, so many cat-scratch patients are misdiagnosed or misdiagnosed. ”

People who love to have kittens are at risk of contracting cat-scratch disease. Li Tong once said that small cats are more likely to spread cat scratch disease than big cats, cats with fleas have a higher chance of bringing Bartonella, like to play with cats, often scratched and bitten people are more likely to be infected, and people who like to be licked by cats are also more likely to be infected. It is understood that from being scratched by a cat to the onset of the disease, the ambush period of cat-scratch disease is generally 3-10 days, and a very small number of cases can last for several months or even more than 1 year.

A scientific study by Xiao Ke, an attending doctor of the Department of Infectious Diseases of the Affiliated Hospital of Southwest Medical University, showed that most patients with cat-scratch disease had a medical record of being scratched, bitten or deeply touched by cats before the onset of the disease. The common symptoms of cat-scratch disease are that 3-7 days after infection, a red rash sub-maculopapular rash occurs in the cat's scratch bite, the pain is not significant, and a very small number of maculopapular rashes become water scars or pus scars, which can occasionally be pierced to produce small ulcers, and heal after 1-3 weeks with transient pigmentation or scarring. After being infected with cat-scratch disease, some lymph nodes will become swollen or swollen, most commonly in the lymph nodes around the head, neck and arms, that is, the lymph nodes in the armpit and head and neck, followed by the abdominal femoral lymph swelling in the inner thighs.

Cat-scratch disease is a condition in which a cat scratches and causes some abnormalities in the body. If there is a lump on the body after petting the cat, it means that it has cat scratch disease. There are bacteria on the body, too.

It is an infectious disease that is mainly caused by bacteria. When a person is scratched by a cat, they can contract the disease. There is a good chance that cats have this disease.

It's the disease of being scratched by a cat. It is very likely that you have been infected by a cat, and the cat has some bacteria on it, and you have touched the cat virus on you.
