For only the second time in its history, the American Red Cross has declared a “national blood supply crisis,” after donations fell to a four-year summer low.
The hotter summer months conventionally trigger blood shortages because people are more likely to injure themselves while spending time outdoors.
And this summer has been particularly extreme. According to the Red Cross, extreme heat, poor air quality, and widespread foodborne illnesses have compounded into blood donations dropping precipitously, causing supply levels to plummet to a historic low.
The news comes amidst record-breaking temperatures this summer, devastating heatwaves that have killed at least 25 people in the US. Public health officials are also battling an outbreak of an explosive diarrhea-causing parasite that’s has spread to 45 states.
