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.
