2. Pneumocystis Pneumonia in AIDS

Pneumocystis pneumonia (PCP) is a serious lung infection common in people with AIDS, a condition caused by the HIV virus that weakens the immune system. Normally, a healthy immune system can fight off infections like Pneumocystis, a fungus that can cause pneumonia. However, in individuals with AIDS, the immune system is compromised, making them vulnerable. Symptoms of PCP include a persistent cough, difficulty breathing, and fever. Treating PCP involves antibiotics, and prevention typically includes medications for those with severe immune deficiency, underscoring the importance of early diagnosis and care in managing health.
