CDC’s Clinical Studies of Pre-Exposure Prophylaxis for HIV Prevention

CDC’s Clinical Studies of Pre-Exposure Prophylaxis for HIV Prevention: "CDC is sponsoring these trials because safe and effective new approaches to HIV prevention are urgently needed. Worldwide, nearly 11,000 people continue to become infected every day (over four million per year). In the United States alone, an estimated 40,000 people become infected each year. Although behavior change programs have contributed to dramatic reductions in the number of annual infections in the United States and many other nations, far too many people remain at high risk. "
