The relative infectiousness of droplets of various sizes just isn’t clear. A related experiment can’t ethically be carried out in humans. But researchers have studied doses of flu virus and found that individuals who inhaled a better dose of flu virus were more likely to get sick and expertise symptoms. Observations of coronavirus outbreaks in processing crops and on cruise ships also help the concept that masks could help defend mask wearers.
