HIV infection weakens your immune system, making you highly susceptible to a large number of bacterial, viral, fungal and parasitic infections. You may also be vulnerable to certain types of cancers. But treatment with anti-retroviral drugs has markedly decreased the number of opportunistic infections and cancers affecting people with HIV. It's now more likely these infections will occur in people who have not had treatment.
Fungal infections
- Candidiasis. Candidiasis is a common HIV-related infection. It causes inflammation and a thick white coating on the mucous membranes of your mouth, tongue (thrush), esophagus (Candida esophagitis) or vagina. Children may have especially severe symptoms in the mouth or esophagus, which can make eating painful and difficult.
- Cryptococcal meningitis. Meningitis is an inflammation of the membranes and fluid surrounding your brain and spinal cord (meninges). Cryptococcal meningitis is a common central nervous system infection associated with HIV, caused by a fungus that is present in soil. It may also be associated with bird or bat droppings. Symptoms include headache, high fever, a stiff neck and sensitivity to light. Cryptococcal meningitis can be successfully treated with antifungal medications, but early treatment is essential. Meningitis is a serious disease that can cause severe complications or prove fatal in a short period of time. Once you've had cryptococcal meningitis, you'll need to be on long-term medication to prevent a recurrence.
