*
Seven patients were previously fully vaccinated.
!The two negative samples had 6 and 7 days since symptom onset (DSSO).

Related to the total of follow-up samples (41) including concordant (5) and discordant (36) samples. The overall rate of virus isolation among the discordant samples is 13.89% (5/36).
&
Two isolations came from consecutive samples of a single individual.
