Identifying Locations with Possible Undetected Imported Severe Acute Respiratory Syndrome Coronavirus 2 Cases by Using Importation Predictions

Topic:

  • Early in the SARS-CoV-2 epidemic, most cases were linked to recent travel history from China, suggesting that air travel played a major role in importation of cases. Using data from February 2020, De Salazar et al. found that daily air travel volume was positively correlated with imported cases of SARS-CoV-2 infection. They estimated that increasing flight volume by 31 passengers/day was associated with 1 additional expected case.
