Health experts say hints are emerging that another possible COVID-19 surge could be on the way.
- So far, no national surge has started yet but as the weather cools and people start spending more time inside, where the virus spreads more easily, the risk of a resurgence increases.
- The first hint of what could be in store for the US is what's happening in Europe and infections have been rising in many European countries, including the U.K., France, and Italy.
