Influenza-induced ITP is infrequent and has never been reported in a third-trimester pregnant woman. Case A previously healthy pregnant woman in the third trimester presented with non-H1N1 Influenza A and a platelet count of 0. She was diagnosed with ITP and treated with intravenous immunoglobulin and oseltamivir. Her platelet count returned to normal by day 8, and she delivered vaginally a normal infant who had no evidence of thrombocytopenia or Influenza. Conclusions Influenza A can induce secondary ITP in pregnancy, and the standard treatment for both ITP and Influenza A is effective. Copyright © 2016 Wolters Kluwer Health, Inc. All rights reserved.
