The global human immunodeficiency virus (HIV) market is expecting to see a rise in incident cases of 9.7% over the next decade, from 276,590 incident cases in 2012 to 303,365 incident cases in 2022.
Across 10 major regional markets, epidemiologists calculated that approximately 5.39 million prevalent cases of HIV occurred in 2012. The number of prevalent cases of HIV is expected to grow almost 15% over the next decade to 6.1 million by 2022.
HIV is a lentivirus (slowly-replicating retrovirus) that causes acquired immunodeficiency syndrome (AIDS), an infectious disease in which progressive failure of the human immune system leads to life-threatening opportunistic infections and/or cancer.
Both HIV-1 and HIV-2 are believed to have originated in non-human primates in West-central Africa and to have transferred to humans (a process known as zoonosis) in the early 20th century.
HIV is transmitted from person to person via bodily fluids, including blood, semen, vaginal discharge and breast milk. It can be spread by sexual contact with an infected person, by sharing needles/syringes with someone who is infected, or, less commonly (and rare in countries where blood is screened for HIV antibodies), through transfusions with infected blood.
HIV has been found in saliva and tears in very low quantities and concentrations in some AIDS patients. However, contact with saliva, tears, or sweat has never been shown to result in transmission of HIV.
Approximately 34 million people are living with HIV around the world, with an estimated 2.7 million new infections each year, and the size of HIV/AIDS incident and prevalent populations vary widely between countries (UNAIDS, 2011).
Sustained levels of high-risk behaviours along with population growth make it challenging to control the future burden of HIV. Furthermore, the prognosis of people with HIV has improved dramatically over time with the introduction of new and improved treatments.
Through to 2022, India will have the largest number of incident cases of HIV. There were 123,269 incident cases in 2012. The number of incident cases of HIV in India will grow 17.3% over the next decade to 144,642 cases in 2022.
The projected growth in the number of new cases in India can be attributed to the population growth among people ages 15-49 years, who are at the highest risk for contracting HIV.
