Global outbreaks, including those of severe acute respiratory syndrome (SARS), Ebola virus disease and COVID-19 reminds us that a public health event in a single location can rapidly become a global crisis. Control of infectious diseases can therefore be considered a global public good, and public health surveillance is a tool that helps achieve it. Timely sharing of public health surveillance data enables better preparedness and response, locally and globally. Public health surveillance is a tool to estimate the health status and behaviour of the populations served by ministries of health, ministries of finance, and donors. Because surveillance can directly measure what is going on in the population, it is useful both for measuring the need for interventions and for directly measuring the effects of interventions. The purpose of surveillance is to empower decision-makers to lead and manage more effectively by providing timely, useful evidence.
During a pandemic, WHO intends to focus on different surveillance components. It shall collect information regarding events through its surveillance activities. WHO recommends the inclusion of pandemic surveillance in any updated pandemic preparedness and response plan. Ideally, the surveillance annexe would be based on this guidance and would outline the surveillance approach to be used during pandemics, including for more details click on link below
