flu season

The 2017-2018 flu season was one of the deadliest in recent history.

A new study identifies signs to look for in the face of a person who may be sick.

Nearly 3 percent of all doctor's visits last week were due to flu-like illnesses.

This new vaccine was much, much more effective than the vaccines used in humans in 2010.

Last year, the vaccine was less than 23 percent effective, but public health officials say they’ve improved their formulas.
