NORTH CAROLINA -- At least 67 people have died so far from the flu this season in North Carolina.

The impact of the disease is now being felt at blood donations.

The winter is already a hard time for the blood donation center but with the snow this month and the large number of flu cases, the Red Cross says it's seen a major drop in donations.

The flu has not allowed people to give blood because if you are sick at all, you're not allowed to donate.

The flu isn't the only thing causing problems for donations. The Red Cross says it canceled hundreds of blood banks across the state this month because of the winter weather.

It's left them short 3,300 units short. It's why they say they are in critical need.
