A campaign to promote AIDS awareness among Hong Kong's truck drivers is being jointly run by City University's Division of Social Studies and AIDS Concern. The campaign follows AIDS Concern's three-day distribution of Safer Sex Kits at Lok Ma Chau last December. It includes the territory's first survey of truck drivers' knowledge of AIDS and related issues. The survey is being conducted by social work lecturer Billy Ho Chi-on and 60 student volunteers. 'It is an effective way to promote AIDS education and raise public awareness while widening students' exposure,' said Mr Ho. In view of China's thriving vice trade, drivers are not only interviewed about their knowledge of AIDS but are also asked whether they visit prostitutes in China and if AIDS has changed such practices. 'The World Health Organisation's study on AIDS and mobility shows that the mobile population - such as businessmen and travellers - are more vulnerable to the disease,' said Mr Ho, a veteran AIDS prevention worker. 'Over 80 per cent of truck drivers in the territory commute frequently between Hong Kong and China because of the booming trade between the two. We aim to learn about the behaviour of this population and their understanding of AIDS.' The survey, targeting 1,000 drivers, is being carried out at Kwai Chung Container Terminals and the Lok Ma Chau border crossing. Findings and analyses are expected to be completed by August, and will be submitted to the Government and non-governmental organisations to help shape future AIDS education and prevention programmes. One of the volunteers, Frank Lau Yin-fung, said the exercise had already helped clear up drivers' misunderstanding of the virus that causes AIDS. 'Direct communication like this enables us to explain things effectively to them,' said Mr Lau, a first-year social work student. The campaign will end on June 12.
