Complication From HIV:

People living with HIV/AIDS are at a high risk of becoming infected by a wide range of different viruses and microbes, including bacteria, fungi, and parasites.

According to the CDC, the most common opportunistic infections that people with HIV/AIDS experience include:

• Candidiasis, an infection by yeast in the genus Candida, which in serious cases can affect the esophagus, trachea, bronchi, and deeper lung tissues
• Coccidioidomycosis, an infection by the fungus Coccidioides immitis, which can cause a form of pneumonia sometimes called desert fever, San Joaquin Valley fever, or Valley fever
• Cryptococcosis, an infection by the fungus Cryptococcus neoformans, which first affects the lungs (causing pneumonia) and brain (causing swelling), before spreading to the skin, bones, and urinary tract
• Cryptosporidiosis, and infection and diarrheal disease caused by the protozoan parasite Cryptosporidium
• Cytomegalovirus infections that can cause pneumonia, gastroenteritis (stomach and intestine inflammation), encephalitis (brain inflammation), and retinitis (an infection of the retina that can cause blindness)
• Herpes simplex virus infections, which can cause bronchitis, pneumonia, and esophagitis
• Histoplasmosis, a lung infection by the fungus Histoplasma capsulatum that causes flu- and pneumonia-like symptoms as well as progressive disseminated histoplasmosis, a disease that can affect other organs
• Isosporiasis, a chronic intestinal infection by the parasite Isospora belli
• Tuberculosis, which is caused by the bacteria Mycobacterium tuberculosis
• Systemic (affecting the whole body) diseases by the bacteria Mycobacterium avium, M. intracellulare, and M. kansasii
• Pneumocystis jiroveci pneumonia, or PJP
• Pneumonia caused by Streptococcus pneumoniae
• Progressive multifocal leukoencephalopathy, a brain and spinal cord (central nervous system, or CNS) disease caused by the JC virus
• Septicemia (blood infection) by the bacteria Salmonella
• Toxoplasmosis, a brain infection by the parasite Toxoplasma gondii.
