Relief efforts in the aftermath of the Hebei earthquake are focusing on getting medical supplies to survivors. Roads covered in ice and blocked by snow were hampering attempts to deliver supplies to remote villages, said World Vision chief executive Dr Chan Sze-tong, who had been touring one of the worst hit areas at Zhangbei. 'We have been told that there is another shipment of medical supplies from the United States in Beijing. The problem now is to get the supplies here and then to the villagers,' he said. 'For many, the clinics are a few hours' walk away. It is a long way to go,' Dr Chan said. Reached at the PLA Hospital in Zhangjiakou, a spokesman said they were sending out 15 teams consisting of 20 medical attendants each. 'There are still people who have physical injuries that have not been taken care of. Some have serious wounds. There are also burns victims. We are trying to give vaccine shots to minimise the spread of cold and flu viruses.' The spokesman said that while other hospitals and clinics in the area were engaged in similar projects, their efforts were not being co-ordinated. Meanwhile, in Hong Kong, the Red Cross has sent representatives to Hebei to monitor the situation. Christine Fang, Red Cross secretary-general, said $180,000 was being allocated to cover medical costs and to support clinics. In addition to flu and cold vaccinations, rehydration formulas would be distributed to help people suffering from severe diarrhoea, Ms Fang said. Dr Chan expected that vitamin supplements and antibiotics would also be needed. Other medical concerns included frostbite. World Vision representatives plan to meet officials in Zhangbei to ask for 25 more lorries to help speed distribution of building supplies. Dr Chan added: 'Many of the first temporary tents built do not allow for proper ventilation, so it is hard to light a fire for warmth. We are trying to build ones that can be used until the spring when rebuilding houses can be contemplated.
