Hospital-Based Active Surveillance


The regional Pacific Hospital-based Active Surveillance (HBAS) system was established in 1997 by WHO under the PPHSN framework as part of the Global Polio Eradication Initiative. The platform has played an integrated vaccine-preventable disease (VPD) surveillance, and the conditions of “suspected measles” and neonatal tetanus (NT) were included from the start. In 2001, surveillance was expanded from “Suspected Measles” to Acute Fever and Rash (AFR) to better identify cases of measles and other diseases like rubella. The HBAS system has since grown to incorporate more than 80 hospitals in 20 Pacific Island countries and areas and over 300 pediatric clinicians and medical officers.

HBAS includes surveillance of acute flaccid paralysis (AFP), acute fever and rash (AFR), neonatal tetanus (NT), and other priority Vaccine-Preventable Diseases (VPDs).
