With high transmissibility and no effective vaccine or therapy, COVID-19 is now a
global pandemic. Government-coordinated efforts across the globe have focused on containment
and mitigation, with varying degrees of success. Countries that have maintained low
COVID-19 per-capita mortality rates appear to share strategies that include early
surveillance, testing, contact tracing, and strict quarantine. The scale of coordination
and data management required for effective implementation of these strategies has—in
most successful countries—relied on adopting digital technology and integrating it
into policy and health care.
