A study released on Monday shows that women using two popular hormonal contraceptives put themselves – and their partners – at greater risk for HIV. While this is a problem for all users of these drugs, it is particularly worrying to people in southern and eastern Africa, where these affordable and easily available contraceptives are used in a very high risk environment. Pam Belluck, science journalist for The New York Times, and Dr. Helene Gayle, president and CEO of CARE, a humanitarian organization with programs to end poverty in nearly 70 countries, talk about the details of the study and what can be done to prevent HIV in Africa.
