Abbreviations: CI = confidence interval, sanitary facilities: the index case shared sanitary facilities with others, social gatherings: the occurrence of a social gathering in the residence, which was attended by the index case. The SARs had a large 95% confidence interval since GLMM allows for a random effect and therefore corresponds to the full range of expected SAR one can encounter in an individual residence unitBack to article page
