A recent study of schoolchildren finds that the youngest students harbor the most germs. Researchers looked at nasal swabs and symptom reports of more than 800 students and staff in Kansas City, Missouri. Kids in pre-kindergarten and elementary school had the highest rates of virus detection compared with older students and staff. The pre-K kids, ages 3 to 5, had the highest rates of actual illness, too. Young children can have up to 10 respiratory viruses as their immune systems are introduced to different infections for the first time. Those viruses include colds, flu and more.

President Donald Trump is in "exceptional health," according to his physician, who evaluated him Friday. Trump underwent a checkup at Walter Reed National Military Medical Center. The visit included lab tests, preventive health assessments, a flu shot and a COVID-19 booster. Navy Capt. Sean Barbabella, Trump's doctor, says the evaluation was part of Trump's ongoing health maintenance plan. The assessment helps prepare Trump for upcoming overseas trips to the Middle East and Asia. Barbabella noted Trump's cardiac age is 14 years younger than his actual age of 79. The White House initially described the visit as a "routine yearly checkup."
