Central and southern regions facing the threat of widespread disease following last week's devastating heavy rains are going to be pounded again in coming days. The National Meteorological Centre announced yesterday that the provinces of Hunan , Guangxi , Guizhou and Sichuan , along with the Chongqing municipality , could expect heavy rainfall between today and Thursday, with some regions expected to be inundated by around 200mm. Hunan, Sichuan and Guizhou sustained the greatest damage when the storms hit last week. This time, the rainy weather is also expected to cover most of the southern regions, Xinhua reports. 'There is a serious warning for these regions [the four provinces and Chongqing] to prevent geological disasters, such as mountain torrents or landslides,' the centre said on its website. Besides flooding, an outbreak of disease is also a serious threat to the regions. At least three people had contracted typhoid in Hunan's Xinshao county, the China Daily reported. Local governments had stockpiled medicine for flood victims. In Hunan's Lianyuan city , medical teams were dispatched to check and treat cases of disease, according to Wu Boyu , from the region's civil affairs bureau. Mr Wu said officials were aware of the incoming storms and had evacuated villagers from fragile homes. He said blankets were most urgently needed. Road and electricity links had not been completely restored. Another big problem was finding funds for injured victims. 'More financial aid should be given to them,' he said, referring to about 1,600 villagers injured in the deluge. 'Their houses were thoroughly cleaned out by the flood. They have no money, let alone bank accounts. How can they afford treatment?' In neighbouring Guangxi province, residents have also been alerted to the danger of more rain, after last week's downpour pushed water levels in the Li River close to the warning mark. 'We held meetings today to prepare for a possible disaster,' said an official from the Guangxi provincial Civil Affairs Department said. According to the Ministry of Civil Affairs, more than 200 people have been killed by floods in 16 provinces this year, with 79 missing and 17 million affected.
