Human Immunodeficiency Virus (HIV) has now hit a large number of the world's population, causing a serious disease called Acquired immune deficiency syndrome (AIDS). Every country is doing its utmost efforts to reduce the spread of the virus as well as spends a large amount of their budget for its control.

According to a recent JAMA internal medicine report, around 41,000 of the yearly HIV transmissions are caused by no diagnosis and care. The researchers revealed that in 2009, there were around 1.1M HIV infected people in the United States, and this number has increased to an incredibly high value due to undiagnosed victims.

Researchers from the United Kingdom presented their findings at the conference held in Seattle, WA, stating that, "Daily dose of antiretroviral drug is effective at securing men having sexual relation with HIV infected men".

While many people are living undiagnosed and many others are deprived of medical care, there are numerous organizations, engineers, and medical researchers working hard to provide easy diagnosis methods for the infected people. Recently, a group of bioengineers at Emory University found the secret areas where viruses like SIV in monkeys could be found. These body parts include nasal cavity, lungs, intestines, lymph nodes, and male genital tract. These contain considerably more virus cells than others, which make them more vulnerable to HIV attack and can be used for easy diagnosis of the virus.

In Rwanda, a recently developed smartphone accessory can diagnose HIV. This is an easy diagnostic choice for poor and more susceptible victims.
