Come fall, the rise of influenza and other seasonal respiratory infections could exacerbate already staggering delays in coronavirus testing, making it easier for the virus to spread unnoticed, experts said.

In typical years, doctors often don’t test for flu, simply assuming that patients with coughs, fevers and fatigue during the winter months are probably carrying the highly infectious virus. But this year, with the coronavirus bringing similar symptoms, doctors will need to test for both viruses to diagnose their patients — further straining supply shortages in an already overwhelmed testing system.
