Methadone treatment is an important means of reducing harm in injection heroin users. Substitution of heroin with methadone protects one from HIV infection. Coverage of methadone treatment is an indicator of protection of public health. In the map a darker colour reflects a higher coverage of methadone treatment in the respective district. Despite the small area size of Hong Kong, spatial variation of methadone treatment coverage can be demonstrated.
