Can the low HIV prevalence in Hong Kong be maintained?

Hong Kong is an area with low HIV prevalence. Public health services provided through the methadone clinics and public sexually transmitted diseases clinics have contributed to the control of HIV in Hong Kong. Nevertheless, surveillance indicates that HIV infections are increasing, especially in young male Chinese. The seropositivity rate of HIV in injection drug users is also increasing. A significant number of sexually transmitted infections, including syphilis and gonorrhoea, continue to occur. Continuing vigilance is required to prevent an increase in HIV infections.
