Morbidity Analysis of the Notifiable Infectious Diseases in China,2018

Introduction Notifiable infectious disease surveillance is important for understanding the trends in morbidity for certain diseases,especially detection of acute infectious disease outbreaks and changing epidemiology.A web-based reporting system was deployed in January 2004,which has improved data collection and speed tremendously.This report provides an updated analysis for reports published in 2013 and 2015.Methods Data from the National Notifiable Disease Reporting System(NNDRS)was used.The NNRDS shows data from 39 notifiable diseases split into three categories(A,B,and C)based on severity and importance.A descriptive analysis was conducted to analyze the morbidity of notifiable diseases in China.Results In 2018,the morbidity of national notifiable diseases was 559.41 per 100,000 population,an increase of 12.88% compared with the average of 2015–2017.The proportion of laboratory confirmed cases was 36.22%,which decreased 4.03% compared with the average of that in the recent three years.Diseases transmitted by direct contact/fecal–oral transmission accounted for the largest proportion,49.37% of the total reported cases,followed by the respiratory transmitted diseases,blood-borne/sexually transmitted diseases,and the zoonotic and vectorborne diseases with a proportion of 25.18%,24.60%,and 0.85%,respectively.Pathogenic descriptive analysis showed that the viral-infected cases accounted for 73.78% of the totals,followed by the bacterialinfected and parasitic diseases.Conclusion The national morbidity of notifiable infectious diseases showed increases in 2018,mostly due to higher morbidity of category C diseases,such as HFMD,infectious diarrhea,and influenza,and these diseases need to be further prioritized in disease control and prevention efforts.Laboratory confirmed cases remain low and need to be improved to improve data quality.

Serological Prevalence Survey Among the High-Risk Populations of Brucellosis-Endemic Areas-China,2019−2020

What is already known about this topic?Timely screening of high-risk population is important to improve the early detection of brucellosis among the endemic areas during the high incidence seasons,which is also required by the National Brucellosis Prevention and Control Plan(2016–2020)(NBPCP).What is added by this report?Seroepidemiological characteristics of brucellosis in high-risk populations were obtained and special occupational populations were found.The seroprevalence of brucellosis has been decreasing compared with that reported in the recent years due to the ongoing implementation of control measures in endemic areas.What are the implications for public health practice?Special occupational populations could be promptly detected using routine screening,which makes it possible to initiate standardized treatment for infected patients as early as possible.It also reminds us to pay attention to special occupational populations to improve their knowledge of brucellosis and reduce the risk of infection.

Brucellosis Knowledge and Personal Protective Equipment Usage Among High-Risk Populations in Brucellosis-Endemic Areas-China,2019−2020

What is already known about this topic?According to the National Brucellosis Prevention and Control Plan(2016–2020)(NBPCP),the awareness rate of high-risk populations in brucellosis-endemic areas should reach 90%by 2020.But the updated results have not been reported.What is added by this report?This report determined the awareness rate of brucellosis(17.74%),utilization of personal protective equipment(PPE)(20.13%),and their relationship with seroprevalence,which provides evidence for the effectiveness of the implementation of NBPCP.What are the implications for public health practice?The results suggest that health education should be conducted for high-risk populations to improve their brucellosis and protection knowledge.
