Beijing has activated a city-wide epidemic reporting system to try to prevent possible heath threats resulting from the rainstorms.

Local health authorities, including hospitals and clinics, have been told to report any cases involving three or more people with symptoms such as fever, diarrhea, pink eye and dermatitis. The public is also encouraged to report to health departments any such cases, according to the Beijing Center for Disease Control and Prevention.

No intestinal infectious-disease outbreaks have been reported in the districts that were worst hit by the heavy rainfall, including Fangshan and Fengtai, the Beijing CDC said.
