This video shows chilling effects of whooping cough on babies Waikato mum Stacey Illingworth is sharing footage of her baby’s struggle with whooping cough to help prevent other parents going through the same trauma. Stacey and her daughter Sativah returned home to Te Aroha recently after spending five weeks in Waikato Hospital. Because Sativah was too young to be fully immunised against whooping cough (pertussis), Ms Illingworth is encouraging all parents to be immunised, and try and avoid contact with anyone who is unwell, especially if they have a cough.
