A seasonal shortage of blood donations could leave hospitals in Oregon, Washington and Alaska with a dangerously low supply during the Fourth of July holiday. Highway accidents tend to increase in summer, especially during the holiday. Colleges and high schools, whose blood drives usually provide a fifth of the agency’s collection, are out of session. Those who donate regularly tend to skip an appointment or two in the summer due to vacations. This year the 4th of July falls on a Wednesday so the "long weekend" vacations are even longer and for all these reasons there is are blood shortages in the summer. The shortage has come even sooner this year and a "red alert" has been issued which means there is only half-a-day supply on hand, the norm being 3 days. The Red Cross is asking particularly for those with negative blood types and O-positive. This is particularly scary going into the 4th of July weekend with all the fireworks and parting going on.
