The principle is mainly complied with the data source existed or not, the data is coincident to the power grid model, the data is unbroken or not and it is reasonable with the physical reality, then it can obtain better convergence and reasonable intra-day check power data. In order to accelerate the information and network pace of the power grid, the SMS notifying can monitoring data quality without time delay. It dredge the vast path for the future power market into use with the wide range, then, can more effective to ensure the convergence and accuracy of safe check calculation, it provides an effective guarantee with the safe and stable operation of the power grid, in the same way, it is also an efficient method to provides effective guarantee for power grid safe operation from the data source.展开更多

Demographic, temporal-spatial distribution were described and analyzed.Results A total of 67,939 cases of 33 different infectious diseases were reported among foreigners.These diseases were seen in 31 provinces of China and originated from 146 countries of the world. The infectious diseases with the highest incidence number were human immunodeficiency virus(HIV) of18,713 cases, hepatitis B(6,461 cases), hand, foot, and mouth disease(6,327 cases). Yunnan province had the highest number of notifiable infectious diseases in foreigners. There were different trends of the major infectious diseases among foreign cases seen in China and varied among provinces.Conclusions This is the first description of the epidemiological characteristic of notifiable infectious diseases among foreigners in China from 2004 to 2017. These data can be used to better inform policymakers about national health priorities for future research and control strategies.展开更多

In July 2016, 12 patients suspected of typhoid were reported to Centenary District Medical Officer by phone. Following reporting, notification forms (T1) were not submitted to district, hence province did not receive district consolidated report (T2) for the notifications. This implies underreporting of notifiable diseases. Study was conducted to evaluate NDSS in Centenary district. Methods: Using updated Centres for Disease Control and Prevention (CDC) guidelines, descriptive cross sectional study was conducted among health workers sampled from all health facilities in Centenary district. Interviewer administered questionnaire and checklists were used to collect data, assess data quality and resource availability. Epi InfoTM 7 generated frequencies and proportions. Results: We interviewed 50 respondents from 13 health facilities and 64% were females. Health worker knowledge was rated low, 26% knew whom to notify and 40% knew forms are completed in triplicate. Reasons for failure to notify notifiable diseases included, unavailability of reporting forms 32% and lack of reporting guidelines 16%. Ninety-two percent were willing to participate. Four health facilities had at least six standard case definitions. The first two patients were only diagnosed at district level. NDSS information was used to procure antirabies vaccine and implement control measures. Conclusion: NDSS is useful, acceptable, unstable and not sensitive. Failure to notify was mainly due to lack of knowledge on NDSS. We recommend training of health workers and mentoring. Fifteen (IEC) case definitions and reporting guidelines were distributed to five health facilities.展开更多

Since January 2013 to August 2014, Beitbridge never submitted T2 forms to the province. Four suspected cases of rabies were reported through the generic report. The electronic District Health Information System 2, T2 forms had not been updated. This discrepancy may imply under reporting of Notifiable Diseases. The study was conducted to evaluate the NDSS in Beitbridge district. Methods: Descriptive cross-sectional study was conducted. Health workers in sampled health facilities were interviewed using questionnaires. Checklists were used to assess resource availability. Epi InfoTM was used to calculate frequencies and proportions. Results: From 11 facilities, 53 respondents were interviewed of which the 59% were females. For Knowledge, 57% recalled at least 9 Notifiable diseases, 11% knew the T1 form required to notify. Respondents willing to participate in the NDSS were 87%. Responsibility to notify was placed other health workers other than themselves by 55% of the respondents. All facilities did not have completed T1 forms. T1 forms were available in 1/11 health facilities. Three outbreaks were reported using the Weekly Disease Surveillance System (WDSS). NDSS information was used for planning and mobilizing resources for indoor residual spraying. It costs an average $12.15 to notify a single case, against $1.50 if it was electronic. Conclusion: NDSS is acceptable, simple, flexible, unstable, not sensitive and useful. Reasons for under reporting were lack of forms, lack of induction and poor knowledge on the NDSS. The cost of operating the NDSS could be reduced if the system is electronic. T1 forms and guidelines for completing the forms should be distributed to all health facilities. On the job training of health workers through tutorials, supervision is recommended.展开更多
