The HIV secret kept from a husband

Thousands of women across South Africa are taking drugs to combat HIV in secret - without the knowledge of their husbands or partners.

Millions of women have been infected by HIV in South Africa, and although many have access to treatment, large numbers are taking their pills covertly for fear of being abandoned.
