Cat crab disease is a rare disease caused by bacteria (Bartonella henselae) that can be transmitted by crabs (often young) cats. A fair proportion of the puppies carry this bacterium without getting sick. In humans, infection leads to sore, swollen lymph nodes in the lymph node station that provides the place where it is scratched. Often this is associated with fever and flu symptoms; This occurs a few weeks after the infection and may last several weeks. If the defenses function adequately, the complaints usually disappear automatically. But the disease can also be accompanied by unclear symptoms, for example with neurological or joint disorder; or far more seriously. The infection can also become chronic.
