I don't care what kind of pandemic is going on. If you're sick, stay home, always.
COVID isn't any different than any other flu going around -- in fact, its probably less dangerous, and more mild. While people are going into hysteria about it, the CDC and other agencies are offering rather common sense guidelines for avoiding catching any disease. If you're sick, stay home (quarantine). If you might be getting sick, do the same. Wash your hands regularly, and don't touch potentially germy surfaces and then your face / eyes / etc. Stay away from Becca's kids.
