You shouldn't be "afraid" of anything, much less a virus. If you'd like to start off with your immune system in the shithouse, nothing helps to get you there quite like stress. The better course of action is to first turn off the tv "doctor" and then work on getting as much fresh air and sunshine as possible along with the usual supplements and eating a balanced diet low in sugar and lots of water. If you are immunocompromised this is especially true. However a semi permanent state of social isolation is also a terrible idea from an immunology stand point, it in turn works on your psyche and we're back where we started from.
