Cytomegalovirus remains viable in naturally infected breast milk despite being frozen for 10 days

Abstract

Cytomegalovirus culture positive breast milk was obtained from four mothers of very premature babies. The milk was stored at 0-5°C in a domestic refrigerator for 48 hours or frozen for different durations at -20°C. Cytomegalovirus survived in breast milk despite being frozen for 10 days at -20°C.
