There was no difference in median age between patients in any wave. Among HP, the proportions female in W1, W2, and W3 were 27%, 46%, and 36%, respectively; all comparisons were significantly different (p&amp;lt;0.05). Among NHP, the proportions female in W1, W2, and W3 were 42%, 48%, and 43%, respectively, none significantly different. Among HP and NHP, the commonest comorbidity in all 3 waves was hypertension. W1, W2, and W3 had 18%, 28%, and 17% of HP with hypertension (significantly different between W3 and W2 (p=0.009) but not W3 and W1 (p=0.79)). There were no differences in the proportion of NHP with hypertension between any of the waves. No patients were vaccinated in W1. Among HP, more were fully vaccinated in W3 than W2 (46% vs 1%, p&amp;lt;0.001). Among HP, 6%, 26%, and 11% died in W1, W2, and W3, respectively, with W3 having significantly lower proportions of HP dying than W2 (p&amp;lt;0.001), but not W1 (p=0.073).
