Methods The case data on other infectious diarrhea and public health emergencies (referred to as events) reported in Hunan Province from 2014 to 2023 were retrieved from the Chinese Disease Prevention and Control Information System. The results were then analyzed using descriptive epidemiological methods. Results From 2014 to 2023, a total of 286 300 cases of other infectious diarrhea were reported in Hunan Province. The average annual incidence rate was 42.37 per 100 000 population, and 3 deaths were reported. By temporal distribution, there were two high-incidence periods. The main high-incidence period was from December to March of the following year, during which a total of 129 831 cases were reported (45.35%), and the secondary high-incidence period was from June to September, during which a total of 83 744 cases were reported (29.25%). By regional distribution, the incidence rates were higher in the eastern and western regions of Hunan, with average annual incidence of 68.05 per 100 000 population and 62.33 per 100 000 population, respectively. By population distribution, the cumulative cases were 160 980 for males and 125 320 for females, with an average annual incidence of 46.41 per 100 000 population and 38.15 per 100 000 population, respectively. Children under 6 years old were the main affected population, accounting for 65.14% (186 500/286 300) of the total reported cases. Among different occupations, the incidence was the highest in children living at home, in whom a total of 175 640 cases (61.35%) were reported, followed by farmers, with a total of 46 172 cases reported (16.13%). From 2014 to 2023, a total of 119 other infectious diarrhea events were reported in Hunan Province, of which 107 (89.92%) occurred in schools or kindergartens, and 86 events (72.27%) were caused by norovirus. Conclusion The high-incidences of other infectious diarrhea in Hunan Province are in winter and summer seasons. The key prevention and control population is children under 6 years old living at home, and schools or kindergartens shall be the pivotal prevention and control sites for other infectious diarrhea events. Before the high-incidence season, targeted prevention and control measures such as health monitoring, food/water source safety supervision, and health education should be implemented for key populations, key regions and key venues.

Methods The case data of other infectious diarrhea reported in Wuhu City from 2005 to 2023 were obtained through the Chinese Disease Prevention and Control Information System. Descriptive epidemiological methods were used to analyze the temporal, regional and population distribution of the infections. Joinpoint regression model was used to analyze the trend change of incidence, and spatial-temporal scan analysis was performed to identify the characteristics of spatiotemporal aggregation. Results From 2005 to 2023, a total of 97 325 cases of other infectious diarrhea, including one death, were reported in Wuhu area. The incidence was 159.37 per 100 000 population. Of these, 52 264 cases were males, and 45 061 females. The incidence was higher in males than in females (167.74/100 000 vs. 150.64/100 000). The number of reported cases (n=29 762, 30.58%) and incidence (1 015.28/100 000) were the highest in the 0-4 age group. By occupation distribution, the highest proportion was seen children living at home (n=27 496, 28.25%) and farmers (n=22 836, 23.46%). By temporal distribution, the infection was unimodal in general between 2005 and 2012, with a peak from July to September (n=7 590, 36.88%), yet presented with bimodal type from 2013 to 2023, with a main peak from June to August (n=26 311, 34.28%) and a secondary peak from January to March (n=16 633, 21.67%). By regional distribution, the highest number of cases was reported in Jiujiang District (n=18 202), and the highest annual incidence was found in Fanchang District (362.15/100 000). Joinpoint regression analysis showed that the reported incidence of other infectious diarrhea in Wuhu City from 2005 to 2023 had an overall increasing trend (AAPC=13.35%, t=3.24, P<0.01), during which rapid increase was seen from 2005 to 2008 (APC=68.37%, t=2.27, APC=13.35%, P<0.01) and slow increment was found from 2008 to 2023 (APC=4.73%, t=6.12, P<0.001). Spatial-temporal scan analysis showed that other infectious diarrhea in Wuhu area was in obvious spatial and temporal aggregation, the primary aggregation area was Fanchang District with the clustering period from April 2017 to September 2023 (RR=2.73, LLR=2 707.39, P<0.001). Conclusion From 2005 to 2023, the incidence of other infectious diarrhea in Wuhu City was higher and tended to climb. Summer is the main peak of the epidemic and most of the infections occurred in population aged 0-4 years. Children living at home and farmers are the groups of high risks, and Fanchang District was the highest incidence area. Our findings suggest that it is necessary to formulate prevention and control strategies for the key areas and population groups, strengthen health education and improve awareness of disease prevention.

Methods Data on hepatitis C registered in Anhui Province from 2012 to 2023 were retrieved through the China Information System for Disease Control and Prevention. Descriptive epidemiologic method was used to analyze the characteristics of reported cases in terms of temporal, regional and population distribution. Joinpoint regression model was used to analyze change trends in hepatitis C. A time series model was developed using SPSS software. The Expert Modeler was used to automatically select the optimal model to predict the incidence of hepatitis C in Anhui Province in 2024. Results A total of 89 722 cases of hepatitis C were reported in Anhui Province from 2012 to 2023, with an average annual prevalence of 12.34/100 000. The results of Joinpoint regression analysis showed an increasing trend in the incidence of hepatitis C from 2012 to 2019 (APC=12.91%, t=13.58, P<0.01) and a decreasing trend from 2019 to 2023 (APC=-5.14%, t=-3.02, P<0.05). The highest number of cases was reported in March, accounting for 9.54% (8 561 cases). The top three reported cases were Fuyang City (14 384 cases, 16.03%), Wuhu City (9 020 cases, 10.05%) and Suzhou City (8 841 cases, 9.85%).

Analysis of laboratory microscopic qualification in detecting Plasmodium in Changsha City from 2018 to 2023 WANG Miaomiao, WEN Lan, ZHANG Bing, HUANG Feifan, ZHANG Pan, TIAN Bin 2025, 23 (1):  40-43.  doi: 10.20199/j.issn.1672-2302.2025.01.008 Abstract ( 72 )   HTML ( 3 )   PDF (896KB) ( 40 )   Objective To evaluate the competence of laboratories in medical institutions and county-level Centers for Disease Control (CDC) in Changsha area in microscopic identification of Plasmodium species, so as to provide technical insights for improving the qualification in malaria diagnosis. Methods The data on Plasmodium species identification from 2018 to 2023 in Changsha area were collected via the Chinese Disease Prevention and Control Information System. The results validated by provincial-level laboratories were used as “gold standard” to analyze the discrepancies in species identification accuracy across laboratories at lower levels. Results Between 2018 and 2023, a total of 212 malaria-positive blood samples delivered by lower level institutions in Changsha area were re-examined and confirmed by changsha CDC, which were completely consistent with the findings validated by provincial-level laboratories. Of the 212 samples, 143 cases were associated with Plasmodium falciparum, 29 with Plasmodium ovale, 28 with Plasmodium vivax, 10 with Plasmodium malariae, and 2 were mixed infections. The overall coincidence rate in species identification was 95.75% (203/212) for medical institutions and 97.64% (207/212) for county-level CDC laboratories. There was no significant difference in the overall coincidence rate of species identified by the medical institutions at different levels (χ2=1.61, P>0.05), yet was significant in specific species across medical institutions as a whole (χ2=50.83, P<0.05). The accuracy was the highest for P. falciparum (99.30%), and lower for P. malariae (80.00%), and all medical institutions failed to identify the two mixed infections. The difference in the overall coincidence rate of species identification among county-level CDC institutions was not statistically significant (χ2=2.76, P>0.05). However, there was a statistically significant difference in the coincidence rate of identification for specific species across county-level CDC institutions as a whole (χ2=37.01, P<0.05). The accuracy was 100.00% in identification of P. falciparum, 80.00%( 8/10) for P. malariae and 50.00%(1/2)) for mixed infections. Conclusion The qualification still needs improving in the laboratories in Changsha City in microscopy of Plasmodium. Targeted training and quality supervision for weaknesses in medical institutions and CDC laboratories are recommended to enhance the laboratory testing capabilities.

Morphological and molecular characteristics of cercaria in Oncomelania hupensis XU Yueye, XU Wei, YANG Yueyang, ZHANG Ansheng, YANG Zhiwei, WANG Guanghui, CAO Zhiguo, ZHAO Jinhong 2025, 23 (1):  44-48.  doi: 10.20199/j.issn.1672-2302.2025.01.009 Abstract ( 85 )   HTML ( 7 )   PDF (1222KB) ( 41 )   Objective To identify the morphological and molecular characteristics of cercariae in the snail Oncomelania hupensis from outdoor feeding base in Anhui Province, and to understand their species classification for molecular biological basis in identification and control of the parasitic trematodes in local snails. Methods By systematic sampling, we obtained the snails at the end of April 2023 from an outdoor feeding base in Anhui Province. Then the samples were crushed to undergo microscopic examination of the presence of cercariae for screening positive snails. Genomic DNA was extracted from the cercariae, and the internal transcribed spacer 2 (ITS2) gene of cercaria was amplified using PCR, and then cloned and sequenced. The sequencing results were aligned with the genes in the GenBank using Basic Local Alignment Search Tool (BLAST). Finally, phylogenetic tree was constructed to analyze the species of parasitic fluke cercaria. Results A total of 300 snails were tested, with 12 testing positive. By the morphological characteristics, the parasitic cercariae fell into three forms, i.e., non-forked long-tailed, non-forked short-tailed and double-forked, which were present in 2, 1 and 9 of the positive snails, respectively. Molecular identification based on the ITS2 gene revealed that the homology of the non-forked long-tailed cercaria was 93.04% with Cryptocotyle lingua, belonging to the genus Cryptocotyle within the family Heterophyidae. The non-forked short-tailed cercaria showed 98.02% homology with Pycnoporus heteroporus and was classified as a trematode of the genus Pycnoporus within the family Lecithodendriidae, and the double-forked cercarial had a homology of 99.62%-100.00% with Schistosoma japonicum, which was Schistosoma japonicum. Conclusion In addition to Schistosoma japonicum, the Oncomelania hupensis in Anhui Province may also be intermediate hosts for Cryptocotyle sp. and Pycnoporus sp.

Epidemiological investigation and analysis of a clustered outbreak of multidrug-resistant pulmonary tuberculosis in a school in Changsha City SONG Lixin, TIAN Bin, XIE Cifu, YIN Pengliang, XIONG Zi 2025, 23 (1):  49-52.  doi: 10.20199/j.issn.1672-2302.2025.01.010 Abstract ( 80 )   HTML ( 2 )   PDF (1222KB) ( 32 )   Objective To analyze the epidemiological characteristics and control measures of a clustered outbreak of multidrug-resistant pulmonary tuberculosis in a school campus in Changsha City for reference in following management of such accident. Methods The information, including the school campus settings, the primary case of tuberculosis and clinical diagnosis, was collected, and then we conducted screening on the close and general contacts for suspicious symptoms of pulmonary tuberculosis by tuberculin skin test (TST) and chest X-ray examination according the procedures specified in the Guidelines for Prevention and Control of Tuberculosis in Schools in China (2020). Drug sensitivity testing was performed for the primary case, and for the pulmonary tuberculosis cases found in screening, multilocus sequence typing (MLST) analysis of Mycobacterium tuberculosis was further carried out to construct phylogenetic tree to determine epidemiological association between cases and effective treatment of the epidemic. Results After identification of the index case, 46 close contacts underwent first round of tuberculosis screening, which revealed that 5 subjects were moderate positive or above for TST, and 2 new active cases were found. No new cases were found after expanded screening of 51 general contacts living in the dormitory at the same floor as the index patient. Four cases were moderate positive or above for TST. Subsequent screening of the close and general contacts revealed 9 cases being moderate positive or above for TST. According to the drug sensitivity test results, all three cases were multidrug-resistant tuberculosis, and the MLST analysis results were used to draw an evolutionary tree. The analysis suggested that there was correlation among the 3 cases involved in this epidemic, and the index case was highly likely to be the patient zero. However, analysis results of the strain sequencing data before and after treatment of the same case showed heterogeneity. Conclusion This clustered outbreak is a multi-drug resistant tuberculosis cluster epidemic. MLST or combined it with drug sensitivity and epidemiological investigation results may provide reference and evidence for inferring the correlation between cases.

Methods The risk assessment framework of Toxoplasma gondii infection in domestic cats was constructed by reviewing the literature reports and monitoring from Shanghai Animal Disease Prevention and Control Center. Based on the results of hazard identification and risk factors of Toxoplasma gondii infection in the domestic cats, the scenario tree of Toxoplasma gondii transmission in domestic cats population was analyzed and mapped. Finally, the risks of Toxoplasma gondii infection and transmission in the domestic cats were qualitatively characterized by potential pathogen release, exposure and consequences. Results The risk factor of Toxoplasma gondii release in domestic cats in urban Shanghai was “cat source”, and the risk level of pathogen release was rated as “medium”. Exposure risk factors were related to feeding methods, feeding raw meat/animal offal, co-ownership of cats and dogs, escape and hunting behavior, for which the risk level of exposure was rated as “high”. The residents in urban Shanghai area exhibited higher health literacy, stronger awareness to scientifically raise pets, for which the risk level of consequences was graded as “low”. According to the risk combination matrix between different steps, the risk of infection and transmission of Toxoplasma gondii was “low” in the domestic cats in urban Shanghai. Conclusion Domestic cats in urban Shanghai are provided with the environmental conditions for toxoplasmosis release and exposure, which are potential risks for human infection with toxoplasmosis, yet the risk level is generally low.

Results A total of 1 256 pieces of literature were retrieved, of which 37 were eventually included. Three articles were published in Chinese, and 34 in English. The results of literature analysis showed that, in terms of function and concept, PHEOC was generally defined as the place where disease control agencies organize or carry out related emergency response services. The case analysis of the PHEOC based on the response event for the flood disasters in Sichuan, Gansu, and other provinces launched by the Chinese Center for Disease Control and Prevention in 2018 showed that PHEOC played an important role in organization and coordination, joint risk assessment, professional technical support, field team dispatch and guarantee, multi-sector information sharing and risk communication. The opinions of experts from special interviews mainly included prospective research on expanding PHEOC under the new situation, strengthening the cultivation of compound talents, actively participating in international public health actions, and incorporating new organizational management models into informatization. Conclusion Based on the context of the integrated development of global public health emergencies, it is necessary to further expand the functions and operation mechanisms of PHEOC in order to enhance the management level in the global public health emergency operations.
