Ever since the disease was first mentioned in the medical literature in 1981, AIDS has spread into nearly every nation on earth and has caused more extensive terror, fear and anxiety than any other medical catastrophe in the twentieth century. It?s high point now. More than three million people around the world die of AIDS each year and, so far-off, more than 25 million people have died of the disease. Today, at least 40 million people are infected and there are more than 14,000 new infections every day. New data reveals that HIV/AIDS epidemic in India is smaller than previous estimates. But the overall number of HIV cases is still very high – and is spreading like a wild fire and if not stopped quickly it will be harmful for the existence of human life on earth.
