Indonesia began immunising quake survivors against measles today and helicopters swept over disaster sites on Java island to look for isolated victims, but help was still too slow for many.
Indonesian Health Minister Siti Fadillah Supari said the government was also evacuating patients from hospitals in the immediate area to more distant cities to relieve overcrowding.

"For now (the hospitals) are starting to get tidy and we have penetrated isolated areas using mobile clinics ... helicopters are dispatching food while airlifting patients," she said.
Saturday's 6.3 magnitude earthquake, centred just off the Indian Ocean coast near Yogyakarta, the main city in the region, killed 5,846 people and left 130,000 homeless.
Hardest hit was Bantul, where entire villages were levelled and homes reduced to piles of wood, tiles and tin. There were no signs of disease such as measles and malaria, but medicines were being sent to affected areas to prevent any outbreaks.
Some survivors said they still lacked the most basic aid.
"We get aid from private donors, but we haven't received any from the government," said Mohammad Aziz, 35, who managed to save his nephew but lost his 68-year-old father in the earthquake.
Amid a heap of rubble, Mr Aziz retrieved the doors from his house, which he plans to use as a floorboard in his tent.
"When it rains, our tent will be flooded. Because there is no flooring, we will be on wet soil," he said, gazing at the spot where he found his father's body.
Idham Samawi, head of Bantul regency, said the government had allocated 500 million rupiah (€42,050) each for two villages, a first step on the road to recovery for Bantul's 75 villages.
"I am optimistic ... the multiplier effect will be remarkable. Those who sold vegetables can sell vegetables again, those who sold eggs will begin to sell eggs," he said.
Some survivors found unusual ways of dealing with the crisis.
About 120 people have taken up residence at the small Karang Turi cemetery in Bantul. With tarpaulin stretched overhead and rugs thrown over graves, they have even managed to get decent sleep and escape nightly rain since the Saturday quake.
"Normally we would be too scared to live here but because of the disaster we have nowhere else to go," said Hernawan. "We are more afraid of the earthquake than living in the cemetery."
In a bid to help ease the trauma, the UNICEF children's agency opened a recreation centre in Bantul. It estimates that 40 per cent of the quake's survivors were children.
