China's AIDS fight
Some 780,000 people are living with HIV/AIDS in China, according to the latest count by the Joint United Nations Program on HIV/AIDS (UNAIDS) in 2011.
People living with HIV or AIDS in China face widespread discrimination and stigma, especially in rural areas where there is a lack of education about the disease.
China has sought to tackle the stigma by establishing laws and regulations prohibiting discrimination against people with HIV.
China's First Lady Peng Liyuan who was appointed World Health Organization's goodwill ambassador for AIDS in 2011, has appeared in public advertisements holding hands and playing with HIV-positive children.
Despite China's fight against AIDS, cases such as Kunkun's suggest inconsistency with official policy.
