The Public Health Preparedness Clinic (PHPC) scheme consolidates the primary care response to public health emergencies such as the influenza pandemic, haze and anthrax outbreak into a single scheme for better management. The Haze Subsidy Scheme (HSS) has also been subsumed under the PHPC scheme. While the specific roles of the PHPC may differ in different threats, the general function of the PHPC remains the same, which is to serve the primary healthcare needs of Singaporeans in times of national need.
