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
