Three weeks ago, Washington, D.C., resident Rebecca Read Medrano started feeling unwell. She had a dry cough, fatigue, nausea and terrible stomach pains that had her bending over.
There was one more symptom, and it was a bit odd. Medrano had largely lost her sense of taste. "My cousin was cooking, and everything he made tasted weird," she recalls.
