Samoa measles crisis: Death toll hits 48

The death toll from the Samoa measles crisis continues to rise with another four deaths in the last 24 hours.

On Sunday afternoon, the Samoan government confirmed the number of measles-related fatalities has hit 48. The vast majority of the deaths so far are those under four years old.

Since the outbreak began on the Pacific island, the Samoan Ministry of Health says 3530 cases have been reported - 173 in the last 24 hours.

Around a third of these - 1048 people - have been admitted to hospital, and 191 of these remain as an in-patient in a health facility.

The disease is believed to have spread to Samoa from Auckland. Efforts to combat the outbreak have been hampered by a low turnout rate for child vaccination, a lack of medical staff and health infrastructure and alternative medical beliefs.

A New Zealand doctor working around the clock in rural Samoa to help administer vaccines told Newshub hospitals are not designed to deal with the number of people they are treating.

"The minute you get hospitals running at 200 to 300 percent capacity - I think it speaks for itself. It's incredibly serious," Dr Scott Wilson said on Monday.

And on Thursday Newshub revealed Fritz Alai'asa, an alternative healer, has been treating patients with measles with alkaline water instead of taking them to hospital.

When Newshub visited his clinic on Thursday there were large numbers of visibly unwell babies and young people - and large gatherings are banned under state of emergency rules.

While waiting to see Alai'asa, a man believed to have measles collapsed and became unresponsive.

Rather than take him immediately to hospital, Alai'asa and his team poured water over his head and neck. After this failed to revive the man, he was eventually taken to the hospital.

After Newshub's revelations, police shut his business down.
