I am wearing a small red ribbon this morning to remind myself and others around me that today is World AIDS Day.
The red ribbon, an international symbol of AIDS awareness, is gaining increasing public recognition as more Chinese, from top leaders to movie stars, wear it today.
Gone were the days when the topic of HIV/AIDS was a public and media taboo(禁忌). Over the past few years, we have watched, read and heard many stories from doctors, volunteers and public health officials at the forefront of HIV/AIDS prevention and treatment.
Quite a few people with HIV/AIDS have e forward to share their experiences on TV or in the media.
The local and central governments have bee more forthing (be helpful) with their new prevention and treatment programmes, and financial input. The latter rose from less than 1 million yuan (US$ 121,000) in 1986 to a pledge of 800 million yuan (US$98.8 million) in the year of 2006.
The change from silence to public and media campaigns with official promises has been remarkable, especially since China battled through the SARS crisis.
But have we got a full grip on HIV/AIDS? What do we know about the extent of HIV/AIDS in China?
The figures, ranging from confirmed cases to estimates, remain debated. After all, no more than a year has passed since the policy of free medical tests was made public. Unknown numbers from the high-risk groups: drug addicts and people working in sex- related places as well as farmers who once sold blood could still be reluctant to e forward.
