Association between coronavirus disease–related symptoms or hospitalization in index case-patients and secondary attack rates in exposed household members from 393 households with a symptomatic index case-patient whose hospitalization status is known, southwest Germany, May–August 2020*

Index case symptom or hospitalization No. index cases, n = 393 No. exposed, n = 1182 No. seropositive
exposed, n = 390		 Observed SAR, % Predicted SAR, % (IQR)† Odds ratio (95% CI)† p value†
Fever 225 666 253 38.0 36.8 (11.8–58.4) 1.93 (1.14–3.31) 0.015
Cough 236 717 272 37.9 36.8 (11.7–58.2) 2.07 (1.21–3.53) 0.008
Diarrhea 91 271 94 34.7 33.2 (9.34–54.5) 0.80 (0.43–1.49) 0.481

 32.2 (10.4–48.7)

Hospitalization 22 67 30 44.8 43.9 (15.2–68.9) 1.22 (0.40–3.75) 0.726

*IQR, interquartile range; NA, not applicable; SAR, secondary attack rate. †The predicted SARs, odds ratios, and p values were calculated from a multivariable generalized linear mixed-effects logistic regression model. The respective references were absence of the symptom or “hospitalization” and adjusted for age of index case-patient as a numeric variable (OR 1.04, 95% CI 1.01–1.06; p = 0.0055).
