Flu Surge Hits Record Highs Across US
There's a big increase in flu cases across the United States, especially in New York and Massachusetts.
The number of cases is the highest ever recorded, with over 71,000 people getting sick in just one week.
In Boston, the number of cases has more than doubled, and most of the new cases are in kids.
Because of this, some schools, like one in Minnesota, have started teaching online instead of in person.
Experts think the holidays and more people traveling might be making the flu spread faster.
New York and Massachusetts reported the highest number of flu cases, with over 71,000 cases in the week ending December 20.
Boston experienced a 114% increase in flu cases, with children being the most affected group.
At least one school in Minnesota switched to remote learning due to the significant spike in illness.
The current flu season is seeing record-high illness rates, the highest since tracking began in 2004.
The holiday season and increased travel are likely contributing factors to the surge in flu cases.
