Three infants whose mothers were either confirmed or highly suspected of having the coronavirus were born in a Wuhan hospital. They are under observation at the neonatal intensive care unit of the Wuhan-based Tongji Hospital.

One of the infants has been in the hospital for six days. A doctor said his mother had an intermittent fever for 12 days before delivery, and her gestational weeks were 41 plus two days. His father had a fever at the same time.

The three infants are being kept in isolation under observation for 14 days. They are currently in good health and have negative nucleic acid test results. Mother-to-child vertical transmission has yet to be determined, according to doctors.
