Reduction in Mobility and COVID-19 Transmission



Keywords (Tags):

Mobility data in 52 countries show that SARS-CoV-2 transmission decreased significantly with initial mobility reductions in 73% of countries. However, mobility explained a smaller proportion of transmission after relaxation of strict control measures in 80% of countries. In these countries, the predictive ability of mobility changed from a median R2 of 74% pre-relaxation to 30% post-relaxation.
