This is important advice. I was lucky to have heard this before getting infected. The immediate infection hit me hard for a week, but I waited a good couple of months before trying any exercise more vigorous than a long walk. Even so, an hour after my first (short!) run, my watch gives me a high heart rate alert. Heart continues to clock 100bpm for the next three hours while I lay around doing nothing. Freaked me out. Take getting back to normal very slowly, and watch for weirdness.
