Health authorities are warning that measles cases are spreading again in New Zealand, with two new infections confirmed in Northland this week, bringing the regional total to 12.

Experts say the risk of further outbreaks remains high, as overseas travellers continue to bring the virus home.

Around 80 percent of New Zealanders are immune, well short of the 95 percent coverage needed to stop the disease from spreading.

Measles is among the most contagious viruses in the world, spreading through the air or by touching contaminated surfaces.

Across the globe, cases are rising sharply in Australia, South-east Asia, the US, Canada and the UK.

Almost all of our previous outbreaks started with unvaccinated travellers returning from overseas, health officials say.

Measles can cause serious complications, such as pneumonia, diarrhoea, and brain swelling.

One in three people infected will need hospital care, and young children, pregnant people, and those with weakened immune systems are most at risk.

Coasties are urged to check their immunisation records to ensure children have received both doses of the MMR vaccine.

Anyone travelling overseas should also make sure they’re fully protected before they go.

If you suspect measles symptoms, including fever, runny nose, cough, sore eyes, or rash — call your GP, Healthline (0800 611 116), or 111 in an emergency.

Early advice helps protect family, friends, and the wider community.
