The problem of AIDS patients raising cats and dogs involves many aspects, including the immune status of AIDS patients, the health risks that pets may bring, and the patients' lifestyle and psychological needs.

First of all, AIDS is a disease caused by the human immunodeficiency virus (HIV), which destroys the body's immune system and makes patients vulnerable to various infections. Therefore, people with AIDS usually have lower immunity and are more susceptible to invasion by external pathogens.

Secondly, pets, especially cats and dogs, may carry various bacteria, viruses and parasites. Pathogens may be transmitted to humans through direct or indirect contact. The risk of these infections may be higher for people with HIV who are immunocompromised.
