Rethinking the COVID-19 Pandemic: Back to Public Health.

The COVID-19 pandemic has highlighted vast differences across countries in their responses to the emergency and their capacities to implement public health measures that could slow the progression of the disease. As public health systems are the first line of defense during pandemics, it has become clear that sustained investment in strengthening public health infrastructure is a major need in all countries, irrespective of income levels. Drawing on the successful experiences of Switzerland, Georgia, and New Zealand in dealing with COVID-19, we suggest prioritizing core public health capacities with links to the International Health Regulations, improving international cooperation, coordination, and multisectoral action, addressing health inequities by targeting vulnerable groups, and enhancing health literacy, including through sophisticated and sustained communication campaigns to build resilience. These measures will ensure that health systems and communities will be better prepared for the disruptions that future disease outbreaks will inevitably bring.
