"Warning: Potential Second Wave of Flu Hits US, Experts Offer Advice"

Doctors are warning of a second wave of flu activity in the Midwest and parts of the South, with flu cases in the U.S. increasing by over 16 percent last week. Public health authorities emphasize that no one is immune from the flu and urge people to get vaccinated, as more than half of Americans haven't received their flu shot. The increase in cases may be due to vaccine hesitancy and people being busier after the pandemic, but doctors stress that it's not too late to get vaccinated and recommend everyone 6 months or older to do so.
