What is cat-scratch disease? People may develop cat-scratch disease after being scratched by a cat. So what is cat-scratch disease? I believe many novice poop scrapers are still a little confused. Let’s take a look at the introduction.

The so-called cat-scratch disease is an infection caused by Bartonella henselae, which is a pleomorphic Gram-negative bacilli that can be observed through a microscope.

When patients become ill, they may have symptoms of swollen lymph nodes and fever. Cat-scratch disease is prevalent around the world every year, with more than 40,000 cases, mostly teenagers and children. There is no difference between men and women. It is more common in warm seasons than cold seasons. .

About 70% of patients with the above symptoms have records of being scratched by cats. Within two weeks of being scratched by a cat, the lymph nodes near the inoculation wound will become swollen and soft to the touch. These swollen lymph nodes are usually found in the armpits, neck, and collarbones. The diameter of the swollen lymph nodes ranges from 1 to 5 centimeters, and are accompanied by an area of ​​redness and swelling around them. This redness and swelling of the lymph nodes can last for several months.

Typical clinical features are primary skin lesions and lymphadenopathy, which are generally benign and self-limiting. However, a small number of patients may develop severe systemic damage, such as granulomatous hepatitis, hepatosplenomegaly, neuritis, and meningoencephalitis, and the entire course of the disease lasts 1 to 4 months.
