Cat Scratch Disease is an infection caused by the bacterium Bartonella henselae, which is often transmitted through scratches or bites from infected cats. Symptoms can include swollen lymph nodes, fever, fatigue, and headaches. Most people recover without treatment, but some may require antibiotics. The disease is more common in children and those with weakened immune systems. To prevent Cat Scratch Disease, it is important to practice good hygiene after handling cats and to avoid rough play that could lead to scratches or bites. Regular veterinary care for pets can also help reduce the risk of infection.
