There were 16 casualties in the Mianyang CDC system and the township amp; county CDC networks were destroyed in the worst-hit counties after the earthquake. The Mianyang CDC quickly launched its emergency response plan for major natural disasters within two hours after the earthquake, prepared and improved the technical guide for disease prevention after the earthquake and rapidly sent out quick response team. With the help of CDC aid teams across the country, Mianyang CDC successfully disinfected and buried 6,767,568 corpses, and disposed of millions of animal carcasses.They also disinfected and sterilised an area of 932.595 million square metres, eradicating 3,514,166 fly and mosquito breeding places and treating 5,254,228 cesspit times. By June 30, they had examined 11,092 water supply units and carried out disinfection of 319.7997 million cubic metres of drinking water. Besides, dynamic monitoring for water quality in the four worst-hit areas in Mianyang urban areas. They organised hygienic enforcement supervisors to develop food safety inspection, regulated catering services of the centralised settlements, destroyed spoiled and expired food and vegetables. The authorities prevented the masses from eating dead poultry or meat from carcasses to ensure no occurrence of food poisoning after the earthquake. Standard administration of the 170 settlements of the earthquake-afflicted people and 132 settlements of evacuated people was carried out in accordance with the rules of "Six Provisions and Four Reinforcements" and this would ensure no recurrence of public health events in the settlements. On Day 3 (May 15) after the earthquake, they established a real-time monitoring and report network of the epidemic situation after the earthquake and monitored diseases and symptoms of the people in the resettled region to ensure no occurrence of major epidemic cases. The monitoring results showed that the number of infectious disease cases was comparable to that in the previous years. Moreover, they carried out intensive vaccination with hepatitis A vaccine in children 41196 person times, stored 100,000 person oral cholera vaccine and monitoring for new sexually transmitted diseases. A total of 10.1265 million copies of publicity materials were organised printed and distributed.
