Java Quake Survivors at High Risk of Disease -------------------------------------------- http://enews.voanews.com/t?ctl=12786B7:3919ACA Officials in Java say wells and streams in the earthquake zone have become polluted with human waste Survivors receive medical treatment at Sarjito Hospital after strong earthquake in Yogyakarta, Central Java, May 27, 2006Relief workers on Indonesia's Java island say people made homeless by last month's earthquake are at risk of disease due to the lack of toilets and running water. Officials in Java say wells and streams in the earthquake zone have become polluted with human waste.  They say improving sanitation for survivors is a priority, and there is an urgent need for latrines to be built in the area. Many roads in the worst-hit province of Yogyakarta are gridlocked Sunday with convoys of trucks and motorcycles carrying relief workers and emergency supplies. Some farmers in the region are returning to their fields to search for food, and for crops to sell to raise money for rebuilding their homes. To the north of the quake zone, Indonesia's Mount Merapi volcano continued to spew lava and clouds of gas and ash.  Indonesian authorities are maintaining a high alert for a possible full-scale eruption. The 6.3 magnitude quake that struck Java on May 27 killed at least six-thousand-200 people and injured more than 20-thousand. Some information for this report was provided by AFP, AP and Reuters. .
