And the second wave of the COVID-19 pandemic might have already started, the researchers said.
What’s going on?
- “In some of the worst performing states, it seems that policymakers have looked for plateauing or slightly declining infection rates. Instead, health officials should look for identifiable local maxima and minima, showing when surges reach their peak and when they are demonstrably over,” said James a Ph.D. student in the school of mathematics and statistics at the University of Sydney, in a statement.
The scientists detailed a new method that looks at COVID-19 case numbers to see evidence of the first and second aves.
- “They found 31 states and the District of Columbia were experiencing a second wave as of the end of July,” according to a press release on the study.
What surges look like
Some states lowered the infection curve by the end of July — a sign of a single surge. Other states see single infection surges. And then there are some states where there was a surge followed by decline followed by a second surge.
- “This is not a predictive model,” James said. “It is an analytical tool that should assist policymakers determining demonstrable turning points in COVID infections.”
