The American Red Cross has declared a blood supply crisis, marking only the second time in its 150-year history that blood inventories have fallen to such critical levels. The organization reported a 25% drop in supply in a single month, a decline that coincides with the summer period when hospitals typically require the most blood due to increased road accidents and outdoor injuries.
Factors Behind the Crisis
Dr. Courtney Lawrence, a representative of the American Red Cross, told the BBC that a combination of extreme heat, widespread wildfires, and a food-borne illness outbreak has exacerbated an already strained supply. High summer temperatures have discouraged people from attending blood drives, and some planned drives were canceled because venues could not provide a safe environment. Wildfires have also diverted attention and resources. Additionally, a cyclosporiasis outbreak—a diarrhoea-inducing parasitic infection—has contributed to the shortage.
The Red Cross, which supplies about 40% of all blood used in the United States, is currently distributing approximately 3,500 more units than normal for this time of year, forcing it to draw heavily on reserves. Dr. Lawrence explained that stockpiling is not a viable solution because donated red blood cells expire after 42 days.
All blood types are urgently needed, with O positive in particularly short supply. The first time the Red Cross declared a blood crisis was in January 2022, during the COVID-19 pandemic and severe winter weather.
Impact on Hospitals
Some hospitals have expressed concerns that the crisis could disrupt routine surgical procedures. Dr. Lawrence noted that facilities are considering whether they may need to divert patients to other trauma centers if they cannot maintain adequate blood supplies for emergencies.
Canada Faces Similar Shortage
Canada is also grappling with a blood shortage. Canadian Blood Services reported that donations have fallen by nearly 20% since the start of June, with weekly appointment shortfalls ranging from 1,500 to 2,500 over the past six weeks. The organization is drawing on existing inventory to meet patient needs, describing several blood type levels as "not sustainable for patient care." Unlike the United States, Canadian Blood Services said the reason for the drop remains unclear, noting that while some seasonal decline is expected, bookings have fallen "well below typical summer patterns."
