UNITED NEWS INTERNATIONAL (UNI) — This flu season could break records in the United States.

The Centers for Disease Control and Prevention is tracking a sharp rise in hospitalizations that shows no signs of leveling off.

According to CDC data, the flu hospitalization rate per 100,000 people is already at 60. That’s close to the peak from 2014-15 — the worst flu season in recent memory.

Acting CDC director Anne Schuchat says one out of ten Americans who died last week died from the flu or pneumonia.

She’s asking anyone who’s sick to stay home from work.

Many folks are doing so; in fact, so many that it could take a toll on productivity.

Outplacement firm Challenger, Gray and Christmas has crunched the numbers behind the CDC data.

Based on an estimate of 18 million employees missing four days of work, it says this flu season could cost the economy $15.4 billion in lost output.
