During the summer of 2009 while home from college and working in a research lab, I woke up one day with a fever, headache, body aches, and nausea and emailed my boss to say that I thought I had a 24-hour bug. I had been healthy all my life and I had no reason to believe this illness would be unlike all the others I’d had before. Surely I would be better in a day or two. The next day, I felt worse and the day after that worse still. I started to get sick at my stomach and quickly became so dehydrated I could barely stand.
