Is AIDS classified as a Class A or Class B infectious disease?

Generally speaking, AIDS is classified as a Class B infectious disease. The specific analysis is as follows:

AIDS is categorized as a Class B infectious disease because it is caused by the human immunodeficiency virus (HIV). Although it has a high fatality rate and currently lacks a cure, its transmission routes are relatively clear and controllable, not reaching the level of urgency associated with Class A infectious diseases. The virus is primarily transmitted through sexual contact, blood, and mother-to-child transmission, and does not spread via everyday casual contact. This characteristic allows the disease to be effectively prevented and controlled through targeted measures. At the same time, HIV severely damages the human immune system, leading to various opportunistic infections and tumors, posing a significant threat to health. Therefore, it must be included in a strict management category, resulting in its classification as a Class B infectious disease for focused prevention and control.

Daily care requires fostering strong health protection awareness, practicing safe sex, and avoiding sharing personal items such as needles or razors that may come into contact with blood. Medical institutions should standardize the management of blood products and medical procedures to prevent cross-infection. People living with HIV should follow medical advice, take medication regularly, maintain a healthy sleep schedule and balanced diet, and strengthen their body's immunity. Society should eliminate discrimination and provide an inclusive environment for those affected, supporting their active engagement in treatment and collectively building a robust defense against HIV/AIDS.
