A measles outbreak in the Pacific nation of Samoa has killed 22 people, nearly all children under five.
The government says 1,797 cases have been reported – 153 since Friday alone.
Samoa declared a state of emergency last week to combat the outbreak. All schools are closed, children under 17 are banned from public gatherings and vaccinations are now compulsory.
The United Nations Children’s Fund (Unicef) estimates Samoa’s vaccination rate is between 28-40%.
It usually takes between 10 days and two weeks for a vaccine to start working.
Some people are reportedly peddling false treatments. One businessman told Australian broadcaster ABC that his “Kangen Water” – in reality, tap water – could alleviate symptoms.
Samoa Attorney General Lemalu Hermann Retzlaff has warned people against discouraging vaccinations in any way.
“Law enforcement is open to receiving notice, complaints, or evidence of any person or organisation, that is discouraging or going as far as preventing our community from vaccination,” he told the Samoa Observer.
Tonga and Fiji have also declared states of emergency to tackle their measles outbreaks in the last month.
However, both countries have far higher vaccination rates – over 90% in both countries – and have so far not reported any deaths.
The Tonga women’s rugby team were put in quarantine on Thursday after a measles outbreak.
