 The study found that having had contact with another individual with a known infection was the main determinant for SARS-CoV-2 infection. This suggests that social distancing measures are effective at reducing the spread of the virus. Additionally, the study found that consumption of alcohol in restaurants or cafes, and possibly attending fitness centers, were weakly associated with SARS-CoV-2 infection. These results suggest that further research should be done to determine whether these activities increase the risk of contracting the virus.
