III. Precautions
This week, the infectious disease epidemics throughout the city keep stable in general, but respiratory infectious disease and intestinal infectious disease show an obvious upward trend over last week, in which, respiratory infectious disease saw a significant increase over the same period of last year.


This week, the case rise for respiratory infectious disease is mainly because A/H1N1 Influenza case continues to rise quickly throughout the city. In addition, the imported second generation of cases and a clustered incidence event occurred in this week. Therefore, this stage should continue to focus on reducing the second-generation cases and strengthening the prevention and control of schools, communities, etc. and intensify the implementation of prevention and control requirements raised by the Ministry of Health to avoid the outbreak of epidemics and improve related response measures.


At present, we are in the peak season of intestinal infectious diseases. As the temperature continues to rise, health institutions at all levels should do a good job in the prevention and control of A/H1N1 Influenza throughout the city, and should also continue to intensify the monitoring and control of dysentery, hand-foot-mouth disease and other intestinal infectious diseases so as to prevent the occurrence of severe diseases, death and clustered cases.
