CSA meaning in Medical ?

Cat-scratch disease (CSD) or felinosis is an infectious disease that most often results from a scratch or bite of a cat. Symptoms typically include a non-painful bump or blister at the site of injury and painful and swollen lymph nodes. People may feel tired, have a headache, or a fever. Symptoms typically begin within 3–14 days following infection.

Cat-scratch disease is caused by the bacterium Bartonella henselae which is believed to be spread by the cat's saliva. Young cats pose a greater risk than older cats. Occasionally dog scratches or bites may be involved. Diagnosis is generally based on symptoms. Confirmation is possible by blood tests.

The primary treatment is supportive. Antibiotics speed healing and are recommended in those with severe disease or immune problems. Recovery typically occurs within 4 months but can require a year. About 1 in 10,000 people are affected. It is more common in children.
