This is kind of a good way to infect someone because how would you know and technically you could limit who was infected.
To me if Joe Biden or Chris Wallace do not come down with it I don’t know how contagious it really is. Unless the social distancing really helps because you know there would have been spit particles in the air in the debate because both Trump and Biden were kind of yelling and animated.
Under most circumstances, social distancing absolutely does help. Look up “Inverse Square Law”.
