ObjectiveTo analyze the epidemic characteristics of the notifiable infectious diseases in West China Hospital of Sichuan University, so as to guide the prevention, control and treatment of notifiable infectious diseases in the hospital and other medical institutions. MethodsDescriptive analysis was used to make statistics and analysis on the data of notifiable infectious diseases in West China Hospital of Sichuan University from 2015 to 2020, and the reporting situation, disease classification and transmission route were summarized. ResultsA total of 21 382 cases of notifiable infectious diseases with 32 types were reported. There was no class A infectious disease reported. There were 16 305 cases (76.26%) of class B infectious diseases and 5 077 cases (23.74%) of class C infectious diseases. The top 5 infectious diseases were pulmonary tuberculosis, influenza, syphilis, acquired immunodeficiency syndrome (including human immunodeficiency virus infection), and viral hepatitis type B. From the trend of the infectious disease reporting, the number of notifiable infectious diseases showed an upward trend from 2015 to 2020. ConclusionsThe report of notifiable infectious diseases in West China Hospital of Sichuan University from 2015 to 2020 mainly focuses on class B infectious diseases and class C infectious diseases. In the future, the prevention and control of infectious diseases should focus on respiratory infectious diseases, blood borne and sexually transmitted infectious diseases.
Medical institutions of China still face two challenges in hospital infections currently: one challenge is from infection, including infectious diseases, multidrug-resistant bacteria healthcare-associated infection (HAI), and classic HAI; the another challenge comes from the management of HAI in medical institutions, such as lack of full-time staff and insufficient capacity, inadequate infection control organizations, insufficient awareness of infection control among medical staff, and unbalanced development. To cope with these severe challenges, we must do the following three aspects: establishing the discipline of HAI, and improving people’s infection control ability through human-orienting; improving the management organization and system of HAI; improving the awareness of infection control among all medical staff, carrying out scientific and orderly infection prevention and control work in accordance with the law, and adhering to evidence-based infection control.

The World Health Organization estimates that 25% of the 57 million annual deaths that occur globall are caused by microbes. A study reported 1 415 species of infectious organisms are known to be pathogenic to humans. Zoonoses constitute 61% of all known infectious diseases, with humans serving as the primary reservoir for only 3% of them. Of the 175 infectious species considered to be emerging, 75% are zoonotic. Zoonotic diseases and their impact on human and animal health are not monitored, prevented, and treated in an integrated way, despite the fact that etiologies and treatments are similar across species. The efficacy and resistance of a drug in one species has a bearing on others, in the context of zoonoses. Further, an RCT involving many species is effective in a natural setting, is robust, and may require fewer human volunteers. One Health is based on a systems approach and a collaborative effort of multiple disciplines – working locally, nationally, and globally – to attain optimal health for people, animals, and the environment. Systematic reviews and meta-analyses have so far been independent and discipline oriented. Pooling of results for diagnostic test accuracies and treatment effects of drugs for zoonoses across species has to be done, since the results of preclinical trials emanate from laboratory animals. The Cochrane Collaboration is the platform of choice to initiate a new group on zoonoses to carry out systematic meta-analyses of diagnostic tests and drug efficacies without bias, thus underpinning the systems approach and One Health.
Objective To construct a multi-dimensional risk assessment system and scale for the prevention and control risk of respiratory infectious diseases in general hospitals, and make evaluation and early warning. Methods Through the collection of relevant literature on the prevention and control of respiratory infectious diseases during the period from January 1st, 2020 to December 31st, 2022, the articles related to the risk assessment of respiratory infectious diseases such as severe acute respiratory syndrome, COVID-19 and influenza A (H1N1) were screened, and the Delphi method was used to evaluate the articles and establish an indicator system. The normalized weight and combined weight of each item were calculated by analytic hierarchy process. The technique for order preference by similarity to the ideal solution method was used to calculate the risk composite index of 38 clinical departments in a tertiary general hospital in Jiangxi Province in December 2022. Results A total of 16 experts were included, including 4 with senior titles, 8 with associate senior titles, and 4 with intermediate titles. After two rounds of Delphi consult, a total of 4 first-level indicators, 11 second-level indicators, and 38 third-level indicators of risk assessment for the prevention and control of respiratory infectious diseases were determined. The reliability and validity of the scale were good. The top three items with the largest combined weights in the scale were spread by aerosol, spread by respiratory droplet, and commonly used instruments (inspection instruments and monitoring equipment). After a comprehensive analysis on the 38 departments, the top 10 departments in the risk index were the departments of medical imaging, pediatrics, ultrasound, cardiac and vascular surgery, infection, emergency, respiratory and critical care, general medicine, otolaryngology and neck surgery, stomatology, and obstetrics. Conclusions This study constructed the risk assessment scale of respiratory infectious diseases in general hospitals, and the scale has good reliability and validity. The use of this scale for risk assessment of general hospitals can provide a theoretical basis for the risk characteristics of prevention and control of respiratory infectious diseases in general hospitals.
Objective To investigate the organizational structure, routine management, emergency response, and material reserves related to the prevention and control of infectious diseases in maternal and child health institutions at all levels in Sichuan, and to understand the construction of emerging infectious diseases prevention and control system in maternal and child health institutions throughout the province. Methods We conducted a survey on the current situation of the epidemic prevention and control system in maternal and child health institutions using a self-developed questionnaire, which was conducted in October 2020 and July 2021, respectively. We conducted comparative analysis on the basic situation, the construction of emerging infectious disease prevention and control systems, and the setting and management of fever clinics/rooms of maternal and child health institutions at all levels in Sichuan in 2020 and 2021. Results In 2020, a total of 166 maternal and child health institutions participated in the survey, and 166 questionnaires were collected, including 17 at the provincial and municipal levels and 149 at the county level. In 2021, a total of 182 maternal and child health institutions participated in the survey, and 182 questionnaires were collected, including 17 at the provincial and municipal levels and 165 at the county level. In 2021, all levels of maternal and child health institutions in Sichuan had established epidemic prevention and control leadership groups. Compared with 2020, the construction of the emerging infectious disease prevention and control system in maternal and child health institutions at all levels in Sichuan in 2021 had improved to a certain extent in terms of establishing epidemic prevention and control leadership groups, hospital area three channel management, three-level pre-examination triage, inpatient area allocation, staff management, and patient management (P<0.05). Compared with 2020, fever clinics that met the requirements of three zones and two channels management, fever clinics that met the requirements of closed-loop management, and management of fever clinics/rooms in maternal and child health institutions at all levels in Sichuan in 2021 had improved to a certain extent (P<0.05). Conclusion Through strengthened construction during the epidemic prevention and control period, the construction of the emerging infectious disease prevention and control system in maternal and child health institutions in Sichuan has improved, but still faces continuous challenges in normalized prevention and control.
Background and Objective Nearly half of million have been reported dead after earthquakes in recent 20 years, and many people always concern seriously about whether those corpses pose a risk to epidemics after earthquakes. An evidence-based approach was conducted to assess the relationship between dead bodies and epidemic disease outbreak systematically. Methods We searched PubMed, The Cochrane Library (Issue 1, 2008), CNKI and WHO website and screened the references of eligible studies. Results A total of 10 papers published beween 1988 to 2007 were included for final analysis, including 2 editorials, 4 reviews and 4 technical reports (technical note or manual). The risk factors for epidemic outbreak after earthquakes were associated primarily with safe water, food and sanitation facilities, as well as the density of population, and no evidence was found that those corpses would pose a risk to the outbreak. But standard infection control precautions should be observed when human corpses were handled. Conclusion Management of dead bodies should be brought into the emergency preparedness system, disaster manuals and guidelines. A community-centered approach to informing communities about the management of the dead following earthquake is also needed. Meanwhile, the myth of about dead bodies and disease outbreak should be dispelled.
Objective To describe the design and application of an emergency response mobile phone-based information system for infectious disease reporting. Methods Software engineering and business modeling were used to design and develope the emergency response mobile phone-based information system for infectious disease reporting. Results Seven days after the initiation of the reporting system, the reporting rate in the earthquake zone reached the level of the same period in 2007, using the mobile phone-based information system. Surveillance of the weekly report on morbidity in the earthquake zone after the initiation of the mobile phone reporting system showed the same trend as the previous three years. Conclusion The emergency response mobile phone-based information system for infectious disease reporting was an effective solution to transmit urgently needed reports and manage communicable disease surveillance information. This assured the consistency of disease surveillance and facilitated sensitive, accurate, and timely disease surveillance. It is an important backup for the internet-based direct reporting system for communicable disease.
Objective To optimize the report procedure of infectious diseases, solve the problems during routine surveillance such as incomplete report and incorrect report, in order to improve the report quality of infectious diseases. Methods Common problems in the report cards which were systematically collected in the infectious disease report management system were analyzed. Then, through negotiation with engineers of the information center, procedures which might easily lead to errors were deleted, report procedures were optimized. Furthermore, clinicians were also trained on infectious disease report from time to time. The entire study was divided into three periods, including baseline period (from October 1, 2012 to December 31, 2013), intervention period (from January 1, 2014 to December 31, 2014) and enhanced intervention period (from January 1, 2015 to December 31, 2015). The incorrect report rate and incomplete report rate were automatically calculated and compared among the three periods to evaluate the report quality. Results Compared with the baseline period, the total incomplete rate in the enhanced intervention period decreased from 8.21% to 3.19% (χ2=103.143,P<0.001), the incorrect report rate of hepatitis B virus decreased from 32.84% to 21.63% (χ2=19.002,P<0.001), and the incorrect report rate of syphilis decreased from 24.93% to 6.86% (χ2=90.416,P<0.001). respectively. Conclusion The infectious disease report system plays a very important role in timely identification of errors and improvement of incomplete and incorrect report, and is of great significance in the management of infectious diseases.
