Breast milk‐transmitted acquired cytomegalovirus infection in an extremely low birth weight infant

Abstract

Key Clinical MessageWe encountered an extremely low birth weight infant with breast milk‐transmitted cytomegalovirus (CMV) infection. To determine the transmission route, we conducted direct sequence analysis of two variable CMV genes, UL139, and UL146. When utilizing breast milk, the possibility of acquired CMV infection should be considered and tested for prompt diagnosis and treatment.
