Local paediatricians are alarmed at recent high rates and hospitalisations of whooping cough (pertussis) in the Bay of Plenty and Lakes health districts, urging people to prioritise getting immunised if eligible.

More than 300 cases have been identified across the Bay of Plenty and Lakes districts since the national whooping cough epidemic was declared late last year, with more than 30 people being hospitalised as a result.

A Health New Zealand statement said paediatricians were most concerned about pregnant women (hapū māmā), babies (pēpi) and Māori whānau who were disproportionately affected.

ESR data also highlighted a concerning number of “ongoing” cases in the region, with multiple babies requiring continued hospital care.

Rotorua Hospital paediatrician Dr Danny de Lore said tamariki living in communities with low immunisation rates were at the highest risk.

He said the continued spread of whooping cough was “deeply worrying”, especially for pēpi younger than 1.

“We’re seeing preventable hospitalisations. We know immunisation is the most effective protection, particularly for young children and hapū māmā.”

Dr de Lore urged eligible people to check their immunisation status and catch up if needed.

Vaccinations were free for babies, children, pregnant women and others at risk.

The best protection for babies is for their mother to get vaccinated during pregnancy.

Health NZ said the pertussis antenatal vaccination was safe and free. It was most effective when given from 16 weeks of pregnancy and should be done during each pregnancy to provide the best protection for each baby.

Babies should also receive their childhood vaccinations on time from six weeks to ensure ongoing protection.

Free vaccinations can be given at GP practices, Hauora Māori or Pacific health services, or at some pharmacies.
