A new study published in The Lancet on July 4th describes China’s recent interventions for prevention and control of COVID-19, specifically the application of containment and suppression strategies. At this moment, China has been able to contain the outbreak and almost stop domestic transmission. Now the suppression efforts continue to prevent any community transmission from imported cases and play a key role in China’s containment measures going forward.  

Through the containment strategy, the proactive finding and management of cases, tracing and quarantining close contacts, and strict restriction or control of population movement are underway. Modeling estimated that without the containment efforts, the COVID-19 cases would have been 67-times higher than they have been so far. Moreover, detection, isolation, and contact tracing with quarantine was the most effective part of the containment strategy as opposed to traveling restriction and contact reductions. 

Suppression strategies must counterbalance the needs of epidemic control with restoration, while maintaining the social life of the community, choosing when it is epidemiologically appropriate to relax or strengthen control. Even during more relaxed physical distancing efforts, proactive case detection and management with contact tracing and quarantine must still be maintained, so that re-establishment of community transmission and a rebound of the epidemic could be avoided. Yet, the significance of this research paper lies in sharing other countries’ experiences in the fight against the COVID-19 pandemic by identifying what strategies and interventions work the most effectively.
