The expanding HIV-1 epidemic aggravates therapeutics and vaccine development programs in India

Human Immunodeficiency Virus Type 1 (HIV-1) displays extensive genetic diversity globally that poses a serious challenge in designing suitable therapeutic measures for protective immune responses in the host. After the first detection of AIDS cases in 1986, India now has the third largest HIV epidemic in world. The HIV-1 epidemic in India is still growing with introduction of new strains/subtypes and this creates a serious problem for the clinician and basic science researchers to find the effective measures. Neighboring countries in the North and North-eastern regions play an important role in the HIV-1 pandemic. An extensive multinational collaborative research effort is needed in order to identify the risk groups and geographic locales is required to monitor HIV-1 spread in Asia and to produce a successful preventive program.
