2. Viral Infections

Viral infections occur when viruses invade the body, often taking advantage of a weakened immune system, such as in people with immunodeficiency disorders. These infections can be more severe and harder to control because the body struggles to fight off the viruses effectively. Common examples include HIV, which can lead to AIDS, making individuals more susceptible to other infections. Without a strong immune response, these viral infections can lead to serious health issues, requiring careful management and treatment to help the body recover and maintain health.
