If you've woken up with sweaty palms, shaky hands and a grumbling stomach begging for relief, you're not alone. The new year brought a warm winter, new habits and an uptick of norovirus — commonly called the stomach flu.

Shares of vaccine makers moved higher early Monday following a CDC report that the U.S. was seeing a significant uptick in acute respiratory illness due to higher rates of seasonal influenza, COVID-19 and RSV.

The United States is experiencing a rise in respiratory illnesses, commonly referred to as a “tripledemic,” involving COVID-19, influenza (flu), and respiratory syncytial virus (RSV), according to the Centers for Disease Control and Prevention (CDC).

RSV and norovirus are making the rounds in the aftermath of holiday gatherings. Just in time to get back in the swing of work and school again, some nasty viruses are getting into the mix, forcing folks to take more time off.
