There are more than 20 babies in Wellington hospital's children's ward, many on oxygen, as the spread of the potentially deadly RSV virus escalates.
There is a warning the flu-like disease has yet to peak, with hospitals all over the country inundated with sick babies and toddlers.
Wellington hospital's child health service clinical leader Andrew Marshall told health correspondent Rowan Quinn the hospital has an entire ward dedicated to babies with the virus, many of them very sick.
