Symptoms can indicate viral infection, so with the pandemic it is best to get a PCR test for COVID-19, and quarantine for at least 10 days along with any close contacts even if the test is negative. If the diarrhea continues, get a stool culture to make certain it is not caused by C. Difficile, a potent bacterial source of intestinal infection.
