Beijing's heat wave has claimed nine lives in one hospital on the same day. Hospitals have issued health warnings saying the old and sick are particularly at risk from sunstroke, dehydration and diarrhoea. While it gave no details of the total death toll, the Beijing Evening News reported that last Saturday one large hospital in the city had nine deaths among the elderly and chronically sick. Every day for the past week, Chaoyang Hospital has seen a stream of patients suffering from sunstroke. As many as 4,500 children a day have been brought to outpatient clinics requiring treatment for colds, fever, diarrhoea and flu. The city has laid on extra sanitary workers to clear up rubbish and prevent the spread of epidemics. The director of the municipal transport company said temperatures inside buses had reached 50 degrees Celsius. Mayor Jia Qinglin promised that air-conditioned buses would be introduced. Yesterday's temperatures were slightly lower at around 34 degrees Celsius, but today is forecast to be another scorcher. More than 50 people have died in Tianjin in the heat wave, a report said yesterday.
