Red Cross Declares National Blood Shortage

January 23, 2026

The U.S. blood supply dropped about 35 percent last month, creating a severe nationwide shortage, the American Red Cross warned this week.

Here’s what you need to know:

• What’s causing the shortage:  The flu outbreak, harsh winter weather, and a slowdown in blood donation events have all contributed to the shortage, the organization said.
• Surprising stat:  Extreme winter weather impacted about 400 blood drives last month. That’s about three times higher than last year’s total.
• No relief in sight:  The weekend forecast includes intense winter weather and frigid temperatures that could lead to more blood drive cancellations or delays, Red Cross officials said.
• Why it matters:  Hospitals and patients rely on a strong supply of donated blood to protect care during emergencies, for cancer care, and for surgeries and other critical needs.
• Quotable:  “This time of year is always challenging for blood collection—but right now, the perfect storm of a long holiday season, record flu activity and winter weather are all impeding donation efforts,” said Dr. Courtney Lawrence, executive medical director for the Red Cross, in a statement.

In Pennsylvania, you can donate blood if you are in good health and feeling well, at least 110 pounds, and 16 or older. The Pennsylvania Department of Health has additional information about blood donation in Pennsylvania. See the Red Cross press release about the national shortage.
