COVID-19 cases across the U.S. follow six monthly cycles, new research suggests. The findings offer crucial insights for disease modelling and getting medical supplies and vaccines to the people who need them.
The dynamics of COVID-19 differ from other respiratory viruses in several important ways,” Donald Burke, dean emeritus at the University of Pittsburgh School of Public Health and senior author on the study, told Newsweek. “Notably, there is an unexpected summer peak in the southern U.S. that has predictably recurred. This is surprising because common respiratory viruses typically peak in colder months in the northern hemisphere.”
The U.S. has seen a significant spike in coronavirus cases this summer, which, as predicted, were the most concentrated in southern states.
“Additionally, we identified oscillating patterns, meaning when cases are elevated in one region at a specific time of the year, they are low in another region and vice versa,” Burke said. “The most prominent oscillation is in the eastern US, oscillating between the north and south.

Non-rural southern cities tend to be more densely populated and also air conditioning due to the higher temperatures in the south.
I’m sure that lower rates of vaccinated individuals in Southern states plays a role too.
Six monthly cycles? To me that reads as “six cycles a month” not “one cycle every six months.”
