“Flurona” isn’t a new Covid-19 variant. Nor is it a new disease or any kind of medical term.

The word flurona has gained popularity as a way to describe the condition of testing positive for both Covid-19 and the flu at the same time. As flu season picks up in the U.S. and in other countries, some hospitals and Covid-19 testing sites in California and Texas in the U.S., and overseas in Israel are reporting instances of people having both influenza and Covid-19.
