Since 1985 in most developed countries, all blood collected for transfusion is tested for HIV, and when possible, some blood products are treated with heat to eliminate the risk of HIV infection. The current risk of HIV infection from a single blood transfusion (which is carefully screened for HIV and other bloodborne viruses in most developed countries) is estimated to be less than 1 in about 2 million in the United States. However, in many developing countries, blood and blood products are not screened for HIV or are not screened as stringently. There, the risk remains substantial.
Stage I: HIV infection is asymptomatic with a CD4+ T cell count (also known as CD4 count) greater than 500 per microlitre (µl or cubic mm) of blood. May include generalized lymph node enlargement.
It is transmitted when this female anopheles mosquito bites a infected person and ingests the parasite which grows in its body. When this mosquito bites another healthy person, the parasite is transferred and the person gets infected. These parasites now travels to the person’s liver where they grow and multiply, eventually causing the blood cell to burst open, releasing the parasite throughout the blood stream. Symptoms mock those of the flu and include chills, headaches, muscle aches, and fatigue. Jaundice and anaemia may follow. Individuals may begin experiencing symptoms a little over a week up until a month after infection.

HIV has been found in saliva, tears, nervous system tissue, blood, semen (including pre-seminal fluid, or “pre-cum”), vaginal fluid, and breast milk. However, only blood, semen, vaginal secretions, and breast milk have been proven to transmit infection to others.
HIV/AIDS is a global pandemic. As of 2016, approximately 36.7 million people have HIV worldwide with the number of new infections that year being about 1.8 million. This is down from 3.1 million new infections in 2001. Slightly over half the infected population are women and 2.1 million are children. It resulted in about 1 million deaths in 2016, down from a peak of 1.9 million in 2005.
If men have low testosterone levels plus fatigue, anemia, and/or muscle loss, they may be given testosterone by injection or through patches placed on the skin. Testosterone treatments can increase testosterone levels and lessen symptoms.

Doctors will use a wide variety of tests to diagnose the presence of opportunistic infections, cancers, or other disease conditions in AIDS patients. Tissue biopsies, samples of cerebrospinal fluid, and sophisticated imaging techniques, such as magnetic resonance imaging (MRI) and computed tomography scans (CT) are used to diagnose AIDS-related cancers, some opportunistic infections, damage to the central nervous system, and wasting of the muscles. Urine and stool samples are used to diagnose infections caused by parasites. AIDS patients are also given blood tests for syphilis and other sexually transmitted diseases.
A transmissible retrovirus that causes AIDS in humans. Two forms of HIV are now recognized: HIV-1, which causes most cases of AIDS in Europe, North and South America, and most parts of Africa; and HIV-2, which is chiefly found in West African patients. HIV-2, discovered in 1986, appears to be less virulent than HIV-1 and may also have a longer latency period.
According to the Centers for Disease Control and Prevention (CDC), from 2010-2015, the estimated rate of HIV infection diagnoses in all 50 US states decreased from 14.2 per 100,000 population in 2010 to 12.3 per 100,000 population in 2015.  In 2015, 39,513 individuals were diagnosed with HIV infection. From 2010 to 2014, the annual number of new HIV infection diagnoses decreased 9%.
