Epidemiological and etiological characteristics of active surveillance of foodborne illness / 公共卫生与预防医学

Objective To realize the epidemiological and pathogenic characteristics of foodborne illness in Shiyan in 2019 and provide targeted measures for the prevention and control work of the foodborne illness． Methods The active surveillance data of foodborne illness in shiyan in 2019 were collected and analyzed. The Salmonella strains isolated from the patients with foodborne illness were tested with serotyping，PFGE molecular classification and drug sensitivity test respectively according to《National foodborne illness surveillance workbook 2019》. Result A total of 3 191 cases of foodborne illness were analyzed. The pre-school children were the highest-risk group of foodborne diseases. Grain and grain product was the main suspicious contaminated food．The main location of eating place was family. A total of 330 samples were tested. The positive detection rate of foodborne illness was 20.30%（73/330）.The main pathogen were Rotavirus and Salmonella,and the detection rates were 11.21%(37/330) and 4.85%(16/330) respectively. The pre-school children were the group with the highest detection rate, which was 57.27% (63/110). The dominant serotype of the 14 Salmonella strains isolated from patients were Salmonella typhimurium and Salmonella enteritis. 14 different genotypes were obtained through PFGE classification and clustering. 64.29% (9/14) of Salmonella strains were multidrug-resistant strains. The drug resistance rates of ampicillin and tetracycline were the highest, which were 71.43%（11/14）and 64.29%（10/14）respectively. Conclusions The publicity and education of food safety should be strengthened and the surveillance network system of food-borne disease should be further improved according to the epidemiological and pathogenic characteristics of foodborne illness in Shiyan in 2019, and the use of clinical antibiotics should be controlled reasonably as well.

Data analysis of active surveillance of foodborne diseases in the sentinel hospital of Shiyan City, 2013-2018 / 公共卫生与预防医学

Objective To investigate the epidemiological and etiological characteristics of foodborne diseases in Shiyan City, and to provide targeted measures for the prevention and control of foodborne diseases. Methods The surveillance data of foodborne diseases reported by Taihe Hospital of Shiyan City from 2013 to 2018 was collected and analyzed. Results A total of 1 742 cases of foodborne diseases were analyzed. The incidence peaked twice during the year, May to August and October to November. The pre-school children (≤6 years old) were at the highest risk of contracting foodborne diseases, and were mainly those in kindergartens, as well as those not in school. Grain and grain products accounted for the highest proportion of the presumably exposed foods． The main location of eating contaminated foods was in households. A total of 1 217 samples were tested, and 92 were positive, of which 71 strains were detected with Salmonella, accounting for the highest proportion. Preschool children and the elderly (≥66 years old) had higher detection rates than others. The food of infants and young children was found to have the highest detection rate. Conclusion According to the epidemiology and etiological characteristics of foodborne diseases in Shiyan City, the publicity and education of food safety should be strengthened and the surveillance network system of foodborne diseases should be further improved.

Detection results from first case of human infection with avian influenza (H5N6) in Hubei Province, China / 中国人兽共患病学报

We analyzed the laboratory detection results from the first case of human infected with avian influenza (H5N6) in Hubei Province,in order to provide a better basis for preventing and controlling human avian influenza in the future and a detected strategy for the detection of suspected cases of human avian influenza for the staff in the laboratory.The case data of epidemiological survey and related laboratory detection results of specimens of infection virus from the different time piont and kinds of specimens were analyzed by descriptive epidemiological methods.The H5N6 nucleic acid from the only early sputum specimens were detected,and while the others were not detected.In conclusion the different specimens of the doubtful H5N6 case should be collected,and the early sputum samples are very important and should be collected and detected.
