HIV positive father Nazir Masih, 43, (L) watches his eldest son Samuel, 26, as he is blessed by a Catholic priest at his wedding on Nov. 11, 2006 in Lahore, Pakistan. Nazir receives anti-retroviral drugs (ARVs), and is now healthy, which made it possible for him to live to see his son get married. The introduction of ARVs to Pakistan has given many people with HIV longer, healthier lives.
