Cat Scratch Disease

Cat scratch disease (CSD), also known as cat scratch fever, is a bacterial infection primarily caused by a bacterium called Bartonella henselae. It is usually transmitted to humans through the scratch or bite of an infected cat, especially kittens, although other feline species can also carry the bacteria. The primary symptoms of cat scratch disease often include a small bump or blister at the site of the scratch or bite, followed by swollen lymph nodes, usually near the area of injury. Other symptoms may include fatigue, fever, headache, and in some cases, an overall feeling of malaise. In most cases, cat scratch disease is self-limiting and resolves on its own without specific treatment. However, severe cases might require antibiotics to manage the infection, especially if complications arise or in individuals with weakened immune systems. Though relatively uncommon, complications of cat scratch disease can include infections of the brain, eyes, heart, or bones, particularly in individuals with compromised immune systems. Preventive measures include practicing good hygiene after handling cats, especially washing hands thoroughly, avoiding rough play with cats that might lead to scratches or bites, and promptly cleaning any wounds caused by cats to reduce the risk of infection.
