I've been seeing coronavirus statistics , comparing age groups of percentages who've caught the virus and which age groups are in the ICU beds . What I didn't see was comparisons , of those who were on board cruise ships , or air flights . Smaller children are much less likely to be on either cruise ships or flying because parents with small children are less likely to be able to afford them . The same is true for those who are in the first stages of moving out of home and managing on their own for the first time . They can't afford cruises or air flights , so are less likely to have been in these higher infections situations .
