Colorado, along with much of the country, is experiencing a summer bump in COVID-19 infections, showing the virus has yet to fall into a seasonal pattern.
Flu, respiratory syncytial virus and other common respiratory bugs typically start spreading in the fall and peter out by spring. In Colorado, the worst points of the pandemic fell in the fall and winter, but COVID-19 hasn’t disappeared in the warmer months, as flu does.
Four years ago, at the beginning of the pandemic, scientists expected the virus would be well on its way to settling into a seasonal pattern by now, said Talia Quandelacy, an assistant professor of epidemiology at the Colorado School of Public Health.
