Predictors of COVID-19 reinfection

Risk Factors	OR	95% CI (lower limit–upper limit)	P
Comorbidity (yes vs. none)	1.121	0.726-1.730	0.606
Had symptoms at first infection (yes vs. no)	1.007	0.653-1.554	0.974
Hospital admission during first infection (yes vs. no)	1.682	1.007-2.811	0.047
ICU admission during first infection (yes vs. no)	0.369	0.116-1.175	0.091

*Probabilistic model is based on probability of having the reinfection. OR=Odds ratio, CI=Confidence interval, ICU=Intensive care unit
