Kawasaki Disease Outbreak in Children During COVID-19 Pandemic.

Abstract BackgroundIn response to the recent information about the outbreak of Kawasaki disease (KD) in children connected to SARS-Cov-2 pandemic, we would like to present a group of six patients hospitalized from March to May 2020 with an inflammatory disease similar to KD. Findings There were four girls and two boys, aged from 15 months to 16 years. They all presented with fever lasting at least five days, irritability, bilateral nonexudative conjunctivitis, lymphadenopathy, mucus membrane changes, rash, edema.Neither the patients nor the other members of the patients' households had a positive history of COVID-19 infection. None of the six children had a positive PCR result for SARS-CoV-2 or a positive results for antibodies to SARS-CoV-2. All patients received empiric antibiotic therapy. Four patients were diagnosed with KD. Three children received standard treatment. One boy did not respond and received an additional 14-days course of methylprednisolone.In two girls, the diagnosis of KD was not made. All patients survived ConclusionFinding a correlation with the Covid-19 pandemic is difficult regarding the situation in our country. According to ECDC, in May 2020 Poland wass still before the peak of the epidemy. The intention of this article is to report that increased hospitalization of children with the inflammatory syndrome is also observed in countries with low levels of transmission of the SARS-Cov-2 virus. Our observation may broaden the knowledge of new inflammatory syndrome, which is not necessarily caused by SARS-Cov-2 but may be worsened by co-infection.
