ABSTRACT
OBJECTIVE:
We aim to explore and compare the effect of global travel restrictions and public health countermeasures in response to COVID-19 outbreak.DESIGN:
A data-driven spatio-temporal modelling to simulate the spread of COVID-19 worldwide for 150 days since 1 January 2020 under different scenarios.SETTING:
Worldwide.INTERVENTIONS:
Travel restrictions and public health countermeasures. MAINOUTCOME:
The cumulative number of COVID-19 cases.RESULTS:
The cumulative number of COVID-19 cases could reach more than 420 million around the world without any countermeasures taken. Under timely and intensive global interventions, 99.97% of infections could be avoided comparing with non-interventions. The scenario of carrying out domestic travel restriction and public health countermeasures in China only could contribute to a significant decrease of the cumulative number of infected cases worldwide. Without global travel restriction in the study setting, 98.62% of COVID-19 cases could be avoided by public health countermeasures in China only compared with non-interventions at all.CONCLUSIONS:
Public health countermeasures were generally more effective than travel restrictions in many countries, suggesting multinational collaborations in the public health communities in response to this novel global health challenge.Keywords
