Torrential rains today battered several parts of western China, killing at least 33 people and heightening fears of a disease outbreak in a mudslide-ravaged town where more than 1,150 have died. Health authorities said survivors of the deadly floods and landslides in Zhouqu, of Gansu province were facing a grim situation after clinics were damaged and vaccines ruined. The bad weather showed no signs of letting up, with at least 33 people killed and 32 missing after floods and landslides in other parts of Gansu and neighbouring Sichuan province. In Zhouqu, 588 people are still missing after the weekend avalanche of mud and rocks, which levelled an area five kilometres long and 300 metres wide. The latest official death toll stood at 1,156 as of today. About 800 medical workers have been dispatched to the region following the mudslides, which state media described as the worst in 60 years in China. More than 2,100 people were left dead or missing and 12 million evacuated nationwide before the Zhouqu incident. The civil affairs ministry said it had not calculated a new nationwide flood death toll.
