Hong Kong, Guangdong and Macau will soon set up a taskforce on HIV and the first Aids database for the region. He Qun, deputy director of the HIV/Aids division of the Guangdong Centres for Disease Control and Prevention, said: 'We will try to put some data on the internet. Information available to the public will be limited but medical professionals can get more.' He said the sensitivity of HIV data on the mainland had made surveillance and disease control difficult. Guangdong has more than 3,000 HIV cases - about one-tenth of the national total, he added. Dr He noted that at least half the province's 150,000 drug addicts share needles, which increases the risk of spreading HIV. In response, the province - with the help of Hong Kong experts - will launch methadone treatment for drug addicts later this year. A daily methadone treatment for each drug addict will cost between 10 yuan (HK$9.4) and 15 yuan.
