Case Report: Delayed Diagnosis of Congenital Malaria by Plasmodium vivax in a Newborn of an Eritrean Woman with Varicella Infection

Congenital malaria (CM) is uncommon in both malaria-endemic and non-endemic countries. It may be caused by any spp., although and are the more frequent etiologic agents. We report a case of delayed diagnosis of CM by in a newborn of an Eritrean . The mother developed pregnancy-related immunodepression and varicella-zoster viral infection 9 days before natural delivery; therefore, the child was admitted in the neonatal intensive care unit (NICU) to administer specific varicella-zoster immunoglobulin prophylaxis and for clinical monitoring. During the NICU stay, the newborn presented a febrile syndrome with vomiting, anemia, and thrombocytopenia. A severe malaria diagnosis was made by detecting trophozoites in the thick and thin blood smears. The infant was successfully treated with intravenous artesunate and clindamycin. Our experience suggests that malaria diagnostic tests need to be included in routine blood analyses in newborns with febrile syndrome from mothers with an epidemiologic link to malaria-endemic areas.
