Abstract Immune thrombocytopenia (ITP) is a common childhood acute autoimmune bleeding disorder caused by numerous viruses and characterized by isolated thrombocytopenia. Although cases of ITP caused by coronavirus disease 2019 (COVID‐19) infection have been reported in adults, pediatric reports are limited. We present the case of a 1‐year‐old girl who developed COVID‐19‐infection‐related ITP with a very low platelet count (0.0 × 104/μL). We searched for COVID‐19‐related pediatric ITP cases and found 10 other cases, with the majority having platelet counts of <1.0 × 104/μL. Although pediatric ITP cases caused by COVID‐19 infection may be severe, further studies are needed.
