Parvovirus

B19 is the causative agent of classical childhood illness known as the 5th disease or erythema infectiosum. The occurrence has a seasonal character, with more dominant waves every 3 to 5 years. Remarkably higher incidence since 2023 is observed globally. Similarly to recent distinct waves od RSV and influenza, even in this case we can suspect a connection with covid pandemic (rapid contagion

after 2 years of social restrictions). The article describes a cohort of patients with PCR confirmed symptomatic parvovirus B19 infection during a period of 12 years (02/2012-06/2024) at the Department of Pediatric Hematology and Oncology, Motol University Hospital. We do not aim at thorough epidemiological analysis, but rather focus on bringing the topic to the czech pediatric community and

describe hematological variety of parvovirus B19 infection.
