HIV testing is essential for slowing the spread of HIV infection. Many people are unaware that they're infected with HIV , so they may be less likely to take precautions to help prevent spreading the virus to others. Dr. Megha Tiwari, Consultant Obst & Gynaecologist at Kailash Hospital Greater Noida explains that for people with undiagnosed HIV, testing is the first step in maintaining a healthy life and preventing HIV transmission. Se emphasizes on the fact that people with HIV who are aware of their status can get HIV treatment (antiretroviral therapy or ART) and remain healthy for many years. She states that the sooner people start treatment after diagnosis, the more they benefit from ART. Even CDC recommends that everyone between the ages of 13 and 64 get tested for HIV at least once as part of routine health care.
