Integrated serological surveillance of population immunity to multiple infectious diseases optimises information gain from public health surveys. Population-level prevalence of antibodies can provide valuable information such as herd immunity to vaccine-preventable diseases (VPDs), progress of elimination efforts for neglected tropical diseases (NTDs), and risk factors and hotspots for arboviruses. Recent advances in laboratory methods (multiplex bead assays) make it possible to concurrently test for antibodies to multiple pathogens, and this approach is being explored as a cost-effective way of conducting integrated serological surveillance. Using results from multiple bead assays on VPDs, NTDs, arboviruses, and SARS-CoV-2 from Samoa, this study will investigate the epidemiology of a range of infectious diseases to identify any gaps in public health programs (e.g. vaccine coverage), overlaps in disease exposure, test for diseases that are not part of routine surveillance (e.g. yaws and trachoma in Samoa), and provide data to measure health burden and inform public health interventions.
