Everyone keeps hoping the virus is "seasonal." That warmer temperatures will dampen the spread. The data on that is total hokum. The flu is seasonal because everyone in the WORLD is exposed in a matter of months and either develops immunity or gets sick first and then develops immunity. The next season's flu comes from viruses incubating in animal populations and agricultural wildlife patterns are seasonal (e.g., pig/chicken raising in Asia, global bird migration patterns). Influenza circulates year around, but in the Summer months, we are mostly immune due to prior exposure. The new version of the flu starts going in Winter and we are all immune again by the Spring/Summer. IMHO, COVID-19 will only have the same pattern by happenstance.
