Abstract
Tuberculosis (TB) is a statutory notifiable disease in Hong Kong. The TB notification rate has declined from 700 per 100,000 population in 1952 to 74.2 per 100,000 population in 2009. Multidrug-resistant (MDR) TB and extensively drug-resistant (XDR) TB constitute around 1 % and 0.1 % of culture-positive TB cases, respectively. Around 1 % of TB patients are HIV infected. The substantial decline in TB notification rates and drug resistance is partly attributable to the implementation of supervised treatment since the 1970s.
Fully funded by the government, the local TB control program comprises five core components: case finding with focus on passive finding, quality DOT, treatment of latent TB infection, BCG vaccination, and health education. The bulk of TB care is delivered free of charge by the Department of Health through 18 chest clinics that are easily accessible. Health promotion messages are disseminated to the whole community as well as to defined target groups.
The last two decades have witnessed a stagnated decline in the TB notification rate in Hong Kong and nearby countries with an intermediate TB burden. This phenomenon is largely attributable to a high burden of latent TB interacting with aging of the TB epidemic, aging of the population, and socioeconomic factors. With aging of the population, frequent population movement, and global resurgence of MDR-TB, there is a continuing need to step up local TB control measures, promote community awareness and support, enhance multidisciplinary and international collaboration, and invest in research and development.
