Infections resulting from cat bites, scratches, and licks are dangerous, but they can be prevented.
Not all cats have fleas, and not all fleas carry the bacteria. But when infected, the disease affects both felines and their owners.
Cat-scratch fever affects 12,000 people annually, according to the CDC. The disease can result in a fever and headache as well as lymph node inflammation. In severe cases, the bacteria can travel to the heart and brain. Only about 500 cases lead to a hospital visit every year, but those numbers are increasing.
While the disease is serious and on the rise, it is preventable with proper cat care and human hygiene.
