In 2015, Dr. Ian Crozier’s blue eye changed color and turned green overnight. The culprit was Ebola. Dr. Crozier thought he’d beaten the disease months earlier, and was shocked to wake up with the unusual side effect. In early April of 2020, CNN host Chris Cuomo shared his Covid-19 side effects. “I was hallucinating, my dad was talking to me, I was seeing people from college, people I haven't seen in forever. It was freaky what happened last night,” he said.
