Measles Virus and Cytomegalovirus Co-infection, in a Child with Recent SARS-CoV-2 Infection, During COVID-19 Pandemic: a Case Report

Measles virus (MV) and cytomegalovirus (CMV) may cause pediatric infection. We report the first described case of MV and CMV co-infection in an unvaccinated 13-mo-old girl, with a recent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, occurred during coronavirus disease 2019 (COVID-19) pandemic. The COVID-19 pandemic context, combined with patient's complex clinical scenario, presenting symptoms as persistent fever, diarrhea, vomiting, maculopapular rash and edema, in addition to high level of inflammatory markers, led to a suspicion of multisystemic inflammatory syndrome in children (MIS-C). The final diagnosis and the successfully management of the case, discharged after resolution of symptoms, was achieved by a proper virological diagnosis and a close two-way cooperation between pediatricians and clinical microbiologists. The report mainly highlights that awareness about measles should be raised in unvaccinated patients with consistent symptoms, even in the COVID-19 era.
