Whooping cough warning

On Friday the Ministry of Health announced that there was a national outbreak of whooping cough. More than 1300 cases of the disease have been reported since the beginning of the year. It's warning parents of young babies to be especially vigilant over Christmas and New Year when families get together, increasing the chance of passing on the disease... especially as adults may have whooping cough but not even know it. Dr Nikki Turner is the Director of the Immunisation Advisory Centre explains.
