A three-week-old baby hospitalised with whooping cough has sparked a warning from health officials for pregnant women to get a booster vaccination against the disease as the number of cases in Northland soars past last year's total.
Last year there were 82 reported cases of whooping cough in Northland, but so far this year there had been 93 cases notified, including the three-week-old baby badly affected last week.
New Zealand has been in the grip of a whooping cough epidemic for more than two years and while the number of cases are dropping in most areas, they are on the rise in Northland, Northland District Health Board medical officer of health Clair Mill said.
There have been two reported deaths in New Zealand from whooping coughs since the epidemic started, but neither were in Northland. However said Dr Mills those deaths illustrated how dangerous whooping cough, or pertussis, as it is also known, is. Babies were particularly at risk.
"We know that only between five and 20 per cent of whooping cough cases are notified, so for every case we know of, there are many more that haven't been reported, so it's important that people get their boosters and their kids vaccinated on time," she said.
