ABSTRACT
Objective To analyze the epidemiological characteristics of influenza in preschool children in Leshan City from 2016 to 2018, and to compare the difference between antigen colloidal gold reagent and nucleic acid detection reagent. Methods A total of 1 100 patients with suspected influenza admitted to Leshan City from January 2016 to December 2018 were selected as the research objects; the clinical data and characteristics of influenza epidemiology of the patients were collected, and the antigen colloidal gold reagent and nucleic acid detection reagent were used to detect influenza. Epidemiological characteristics; using nucleic acid detection as the standard to evaluate the diagnostic value of antigen colloidal gold reagent detection methods. Results The nucleic acid detection gold standard, antigen colloidal gold reagent method to detect influenza The sensitivity and specificity of the pathogen are both greater than 80%, and the AUC of influenza pathogen detection by the antigen colloidal gold reagent method is greater than 0.90, which has high application value . From 2016 to 2018, Leshan City was dominated by type B Y and type A H3N2; the main clinical features were cough, runny nose, and fever (P<0.05); the distribution of characteristics showed that there was no statistics on the sex of children with influenza Significantly, children less than 5 years old accounted for the highest proportion, and the proportion of children in winter and Spring Festival was significantly higher than that in summer and autumn, and the difference was statistically significant (P<0.05). Conclusion From 2016 to 2018, influenza virus infections in preschool children in Leshan City were mainly type Y and type A H3N2, and showed obvious age and seasonal characteristics. The antigenic colloidal gold reagent was used in clinical screening for children, but the test was negative. Children who are at high risk should be diagnosed with nucleic acid method as soon as possible.
ABSTRACT
Objective To analyze the epidemiological characteristics of reported malaria cases in Leshan City, so as to provide insights into malaria control. Methods The data pertaining to malaria cases and epidemiological individual information in Leshan City from 2012 to 2018 were captured from the National Notifiable Communicable Disease Reporting System and the Information System for Parasitic Diseases Control and Prevention, and a descriptive epidemiological analysis was performed. Results A total of 34 malaria cases were reported in Leshan City from 2012 to 2018, and all cases were confirmed as imported malaria cases by Sichuan provincial malaria diagnosis reference laboratory. Of all 34 cases, there were 14 vivax malaria cases, 18 falciparum malaria cases, a malariae malaria case and an ovale malaria case. The sites where malaria parasite infections occurred mainly included African areas (accounting for 58.82%) and Southeastern Asian areas (accounting for 29.41%), and the malaria cases were mainly reported in January, February, June and July, which accounted for 65.63% of all cases. The cases included 33 men and a woman, and had ages of 21 to 59 years. The cases’occupations mainly involved overseas peasants, technical workers and businessmen. The duration from onset of malaria to diagnosis ranged from 0 to 31 days, and the percentage of definitive diagnosis was 85.29% at initial diagnosis. Conclusions There are no local malaria cases in Leshan City; however, imported malaria cases are reported. The monitoring, management and health education of overseas returners should be further strengthened and malaria training should be improved to enhance the diagnostic and treatment capability in professionals, so as to consolidate malaria control achievements.

ABSTRACT
Objective To analyze the epidemiological characteristics of malaria in Leshan City,so as to provide the evi-dence for formulating the strategy and measures for consolidating the achievements of malaria elimination. Methods The data of epidemiological characteristics of malaria in Leshan City from 1950 to 2015 were collected and analyzed with the descriptive epidemiology method. Results There were four larger scale epidemics of malaria in Leshan City from 1950 to 2015. The order of malaria in infectious diseases dropped from the first to the twentieth. The peak season for malaria epidemics ceased. The Plas-modium species,patient age,occupation and sex distribution of malaria were different in the different periods. In November 2016,the whole city achieved the national standard for malaria elimination. Conclusions After years of prevention and con-trol,the epidemiological characteristics of malaria have changed significantly in Leshan City,and the effect of anti-malarial mea-sures is significant. In the future,we should strengthen the monitoring,and prevention and control of imported malaria.
