[Epidemic trend on notifiable communicable diseases from 2010 to 2015 in Beijing].

OBJECTIVE

To analyze the trends and epidemiological characteristics of notifiable communicable diseases from 2010 to 2015 in Beijing so as to provide reliable reference data.

METHODS

Data on the epidemiological characteristics was gathered and analyzed through the monitoring programs on notifiable diseases, reported by the China Information System for Disease Control and Prevention, from 2010 to 2015.

RESULTS

A total of 764 290 cases of notifiable communicable diseases were reported from 2010 to 2015 in Beijing. The annual reported incidence on notifiable communicable diseases showed an annual downward (χ(2)=1.25×10(4), P<0.01), with rates between 498.95/100 000 and 828.45/100 000. The annual reported incidence rates of intestinal infectious diseases and respiratory infectious diseases also showed an annual downward (χ(2)=1.25×10(4), P<0.01; χ(2)=4.97×10(2), P<0.01), which accounted for 39.72% and 33.01% among the total classes A and B reported cases, respectively. The average annual reported incidence rates in males were higher than that in females. The average annual incidence of children under 7 years old appeared higher than that of the other age groups that accounted for 47.79% of the total reported cases. High incidence mainly appeared in children that living scattering around which accounted for 31.64% of the total reported cases. The first three leading incidence rates seen in other infectious diseases were infectious diarrhea, hand-foot-and-mouth disease and dysentery for the last consecutive 6 years. The laboratory diagnosed rate on notifiable disease was 16.67%, but with a trend of annual increase.

CONCLUSIONS

Intestinal infective diseases kept the highest incidence among all the notifiable communicable diseases, suggesting the necessity of improving the prevention and control programs on notifiable communicable diseases in preschool, especially in those children with their houses scattered around. Programs on laboratory diagnosis also need to be strengthened.
