The American Red Cross issues an emergency call for blood and platelet donors.
Red Cross officials say 37,000 fewer donations were made in November and December.
They say it could be attributed to busy holiday schedules, snowstorms, and severe weather.
Red Cross says due to those factors, nearly 100 blood drives were forced to cancel in December, but others are planned.
If you'd like to donate, a drive is scheduled Friday at Eastern Illinois University's Andrews Hall starting at one.
