Will the summer weather decrease the SARS-CoV-2 spread?
Respiratory viruses spread less readily in summer than in winter for reasons that are not well understood. Dry air and higher temperatures are slowing down the spread of respiratory viruses. Absence of school attendance, more time outdoors, greater household ventilation, warmer temperatures facilitating virus inactivation and higher vitamin D levels are all likely to play a part. Although social distancing measures are implemented, the summer weather should play a role in hampering the spread of COVID-19. However, based on the analogy of previous influenza pandemic, it is unlikely that summer, on its own, could stop transmission of SARS-CoV-2.244,245
