The national flu epidemic continues to spread.
Hospitals are overwhelmed and vaccines are now getting harder to come by.
From coast to coast, Americans are waging a losing battle against this nasty flu strain.
Doctors, overrun by patients, are running low on flu shots and tests as the virus spreads.
More than 128 million vaccine doses have been distributed nationwide. But clinics can't keep up with the demand. And pharmacists are struggling to fill prescription drug orders.
Friday morning, schools across the country are reporting hundreds of students are out sick.
One district in Oklahoma even canceled class after a quarter of the students became ill.
The flu season hasn't even hit its peak, but it's already been deadly.
It's not just the flu though. Another virus, a nasty stomach bug called norovirus, is also on the move throughout the country. Doctors said it's extremely contagious and another serious concern for doctors.
