While it’s firmly established that the virus transmits best in winter, in common with most other respiratory viruses, the UK is currently experiencing a summer surge. There have also been major Covid-19 epidemic waves in regions such as South America and India outside winter. From the beginning of the pandemic, one major question was to what extent Covid would display a seasonal behaviour with higher case numbers in winter. Population immunisation through both prior natural infection and vaccination will decrease the R number, by reducing the fraction of the host population through which the virus can spread. At this stage, Covid will join the 200 other seasonal endemic respiratory viruses in circulation globally.
