Discussion questions for recitations

Week 12

  • Does the common cold protect against Covid? Even just a little bit, occasionally?
  • People floated a hypothesis at one point that, by capturing even a portion of the virus particles you inhale, a mask might result in you getting less sick. Can you justify this hypothesis? Why wouldn’t a virus either catch hold and harm you, or (if you have immunity) not do so – independent of virus-particle quantity?
