A fresh look at an old problem

The incidence of HIV infection has not changed in a decade. Since 2005, about 2·6 million people have become newly infected with HIV annually. Young women, particularly adolescent girls, account for a disproportionate number of new HIV infections. Development of successful strategies to prevent HIV acquisition might require more creative approaches to meet the needs of the most susceptible populations, including exploration of the role of sexually transmitted infections, such as herpes simplex virus type 2 (HSV-2), in HIV infection.
