PathWays Case Study: February 23

A 43-year-old Minnesota native proudly presents to the local blood donation center to donate his 25th red blood cell unit. His past medical history includes hypertension, for which he takes a beta blocker and a daily aspirin. He has no significant surgical, social, or family history that has precluded red blood cell donation in the past. Ten days ago, he returned from a family reunion in Cancun, Mexico. During his patient interview, he delightedly shared his families' recent beach travels, as well as a sightseeing tour of Mexico City. Unfortunately, he is subsequently deferred from donating, due to his recent travel to a Zika-virus-endemic country.
