The \"index participant\" is the main enrolled participant in the household who is randomized to the intervention or control arm.\n\nThe participant will be in the study for about 40 months and will have 11 research visits: one at baseline and then every 4 months through month 40. At visits, staff will do breathing tests (spirometry before and after an inhaled medicine), measure exhaled carbon monoxide, check blood pressure, measure height\u002Fweight at selected visits, and ask questions about symptoms, smoking, infections, vaccines, and quality of life. The participant will also wear an activity monitor (accelerometer) for 2 weeks at baseline and at follow-up visits. If individual is a household member (not the index participant), the participant may be asked to complete baseline and follow-up assessments every 4 months through month 40, will receive the influenza vaccine and will primarily be asked to use masks and handwashing during household respiratory illness episodes (only if the index participant is randomized to the intervention) and will not be asked to wear an activity monitor.
