How many COVID-19 cases could have been prevented in the US if its interventions were as effective as those in China and South Korea?
Category: Article Summary
Topic: Transmission
- Liu et al. modeled how many COVID-19 cases could have been prevented in the US if the US had implemented comprehensive and strict lockdown measures like in Wuhan, China or widespread testing as in South Korea.
- Researchers estimate that if these measure were implemented at the early stage of the outbreak (March 10), 99% (1.15 million) fewer cases could have been expected by the end of the epidemic. If actions were taken on April 1, this number could have decreased to 66% (with the China-like scenario) and 73% (with South Korea-like scenario), highlighting the importance of early interventions and the need for swift response.
