11. Gatherings with children could be risky
Children under 5 are not vaccinated, and many older children have not been either. It is easy to forget that younger children can carry the virus, because they are less likely to show symptoms. Going to a gathering with young children carries risk.
12. Check local mask rules
Rules vary considerably from place to place, which means that risk does as well. Check local laws before you travel so you can assess where you may or may not want to go. Several organizations, like AARP, keep up-to-date lists.
13. Check rules on indoor space capacity
MIT conducted a study about how much the volume of a space, time spent in a space, and airflow influence virus spread. Review the rules when you go to events at indoor spaces. Remember, mask wearing and social distancing are absolutely necessary in crowded spaces.
14. Have a Zoom holiday party
People forget that Zoom was not universally used before the pandemic. It has become a staple of corporate life to prevent infection. While not the same as being together in person, Zoom, Facetime, and other video services provide an alternative to travel and in-person gatherings. There are plenty of lists of Zoom party ideas.
15. Roll down windows in taxis and Uber cars
A car is an unusually confined space that makes it easy for the virus to spread. Wear a mask and roll down a window when travelling with an unknown driver. Do ask the driver to wear a mask properly, covering from nose to below the chin.
