Although an immune response has been demonstrated in patients who have had Covid19, re-infec­tions are being reported with increasing frequency. To avoid confusion with cases of persistent infec­tion, the criteria for the diagnosis of reinfection require a minimum time interval between episodes and the performance of complementary tests that are not accessible to most clinicians. Two cases of reinfection in pediatric patients, attended in primary care and with a short time interval between the first episode and the reinfection are presented.
