Papua New Guinea has one of the fastest growing HIV epidemics in the Asia-Pacific region, with many unaware they have the virus

After battling illness for years, Nancy Karipa tested positive for HIV in 1999. She had just given birth to her first child. “It was a crossroads moment for me, with the fear of denial, but I chose action,” Karipa, who is now in her 50s, said at an Aids awareness event in Papua New Guinea’s capital Port Moresby in December.
