According to the South Texas Blood & Tissue Center, the South Texas region, including San Antonio, is running dangerously low on blood supplies.

As a result, the organization is ramping up its local commemorations of National Blood Donor Month for January like the red smokestacks at the Quarry.

They say that the need for O-negative blood is particularly urgent.

“Our South Texas communities stepped up to donate during difficult times in 2017,” said Dr. Samantha Gomez Ngamsuntikul, STBTC associate medical director, in a press release. “Unfortunately, as time passes, people get back to their routines and tend to forget that the need for lifesaving blood continues.”

Blood donations typically slow down over the holidays because high schools and colleges are off throughout most of those months and don't schedule blood drives at those times. That's why National Blood Donor Month is in January.
