Identification of Early Warning Signals of Infectious Diseases in Hospitals by Integrating Clinical Treatment and Disease Prevention

The global incidence of infectious diseases has increased in recent years,posing a significant threat to human health.Hospitals typically serve as frontline institutions for detecting infectious diseases.However,accurately identifying warning signals of infectious diseases in a timely manner,especially emerging infectious diseases,can be challenging.Consequently,there is a pressing need to integrate treatment and disease prevention data to conduct comprehensive analyses aimed at preventing and controlling infectious diseases within hospitals.This paper examines the role of medical data in the early identification of infectious diseases,explores early warning technologies for infectious disease recognition,and assesses monitoring and early warning mechanisms for infectious diseases.We propose that hospitals adopt novel multidimensional early warning technologies to mine and analyze medical data from various systems,in compliance with national strategies to integrate clinical treatment and disease prevention.Furthermore,hospitals should establish institution-specific,clinical-based early warning models for infectious diseases to actively monitor early signals and enhance preparedness for infectious disease prevention and control.

Prevention and Control Strategies of Nosocomial Infection and Effectiveness Evaluation in a Tertiary Teaching Hospital during the Epidemic of COVID-19

Objective: To evaluate the role of prevention and control strategies for nosocomial infection in a tertiary teaching hospital during the sudden outbreak of Corona Virus Disease 2019 (COVID-19). Methods: The hospital initiated an emergency plan involving multi-departmental defense and control. It adopted a series of nosocomial infection prevention and control measures, including strengthening pre-examination and triage, optimizing the consultation process, improving the hospital’s architectural composition, implementing graded risk management, enhancing personal protection, and implementing staff training and supervision. Descriptive research was used to evaluate the short-term effects of these in-hospital prevention and control strategies. The analysis compared changes in related evaluation indicators between January 24, 2020 and February 12, 2020 (Chinese Lunar New Year’s Eve 2020 to lunar January 19) and the corresponding lunar period of the previous year. Results: Compared to the same period last year, the outpatient fever rate increased by 1.85-fold (P P Conclusion: The nosocomial infection prevention and control strategies implemented during this specific period improved the detection and control abilities for the COVID-19 source of infection and enhanced the compliance with measures. This likely contributed significantly to avoiding the occurrence of nosocomial infection.

Damage and Control Suggestions for the Emerging Disease Coffee Root Rot

[Objectives]The paper was to elucidate the symptoms,morphological characteristics,etiological factors,and current extent of damage associated with coffee root rot disease.[Methods]The symptoms,morphological characteristics,and etiological factors associated with coffee root rot disease were systematically observed,described,and analyzed.The assessment of damage was carried out using a specialized investigative methodology.[Results]The application of bottom fertilizer containing Fusarium incarnatum facilitated the pathogen's entry through root wounds during transplantation,resulting in the development of water-soaked depression lesions in the affected areas.This infection significantly reduced the number of lateral roots in coffee plants,leading to symptoms such as wilting,withering,and ultimately,the death of the aboveground foliage.F.incarnatum exhibited three distinct types of spore morphology:macroconidia,which were sickle-shaped;mesoconidia,which were spindle-shaped;and microconidia,which were oval-shaped.The incidence rate of the disease in the affected region reached 100%,with a disease index exceeding 91,indicating severe damage.[Conclusions]This study serves as a valuable reference for the prevention and management of the emerging disease known as coffee root rot.

Prevention and Control Technology of Potato Soil-borne Diseases

In recent years,potato soil-borne diseases have occurred severely.The investigation shows that potato Fusarium wilt greatly affects potato yield,leading to a yield reduction rate of 21.8%.Potato powdery scab shows very mild symptoms on potato tuber,basically with no symptoms in some plots,but shows obvious symptoms on the root system.A large number of nodules which are produced on one side of the root system seriously affect water and fertilizer absorption function of the potato root system.Potato tubers expand slowly,leading to small potato tuber,low yield and low commodity rate.The fungus can survive in soil for more than 10 years.Potato soil-borne diseases are harmful and are difficult to control.Susceptible plants can be detected by high definition chromatographic control method and pathogen detection.For prevention and control of potato soil-borne diseases,first of all,disease-resistant varieties should be chosen and virus-free potato seeds are used for sowing.Secondly,metham and dazomet can be used to treat soil in order to prevent and control potato soil-borne diseases.The results showed that the dead seedling rate treated by metham was reduced from 35%to 12.5%compared with the blank control,and the yield was increased by 44.09 kg/ha,with an increase rate of 18.2%.Compared with the blank control,the dead seedling rate treated by dazomet was decreased from 35%to 7.5%,and the yield was increased by 38.10 kg/ha,with an increase rate of 15.7%.The soil treatment received obvious yield increase effect.
