| As contact risk rose from low to medium to high, the percentage of respondents with one or more at-risk health conditions rose linearly from 37.7% to 45.0% to 56.3% (p<0.18 by chi-square test; r = 0.15, p<0.07). |
Of those respondents from families in which all members had been vaccinated, only 34.1% had one or more at-risk health conditions, compared to 49.6% of those from families in which at least some of the members had not been vaccinated (p<0.09). |
The percentage of respondents with one or more at-risk health conditions tended to rise as a function of their unwillingness to comply with a directive to stay at home during an epidemic: no visits (46.1%), one or two (38.8%), and three or more (75.0%)(p<0.08). |
| Those who would be most vulnerable or susceptible to an epidemic were actually most likely to be engaging in multiple contacts with friends, family, and guests. |
Those who were most susceptible to an epidemic were least likely to be prepared for it in terms of anticipatory vaccination. |
Those who were willing to visit others even during an epidemic were among those most at-risk because of their health status. |
