Abstract:
Objective To analyze the seasonal and epidemiological characteristics of community-acquired pneumonia (CAP) in Chuzhou from 2010 to 2022. Methods The epidemiological data of CAP in Chuzhou from 2010 to 2022 were obtained from the center for diseases control and prevention of Chuzhou City, Anhui Province. After inclusion and exclusion, a total of 1 053 cases were enrolled. General data were collected. Then the characteristics of CAP patients in terms of gender, age, regional and seasonal distribution and pathogenic bacteria distribution were analyzed. Results A total of 316 patients with CAP, with a prevalence rate of 30.01%, including 152 males (48.10%) and 164 females (51.90%). Regarding age, 86 cases (27.22%) at 19-40 years, 106 cases (33.54%) at 41-60 years, and 124 cases (39.24%) at >60 years, suggesting a statistical difference in the CAP detection rate among different genders and ages (P<0.05). Seasonally, 118 cases (37.34%) were detected in spring, 13 cases (4.11%) in summer, 49 cases (15.51%) in autumn, and 136 cases (43.04%) in winter, with the highest CAP detection rate in winter, followed by spring. Pathogenic bacteria were positive in 198 of 316 patients, with a detection rate of 62.66%. A total of 125 strains of pathogenic bacteria were detected in sputum culture, of which 138 cases were Gram-negative, mainly Escherichia coli (24.24%, 48/198), and 60 cases were Gram-positive, mainly Streptococcus pneumoniae (14.14%, 28/198). Among 198 patients positive for pathogen detection, 41 cases were detected in spring, 37 cases in summer, 56 cases in autumn and 64 cases in winter. The drug sensitivity results showed that Escherichia coli had the highest resistance rate to ampicillin and cefazolin, and was sensitive to imipenem and other antibiotics; Streptococcus pneumoniae has the highest resistance rate to penicillin and erythromycin, and is sensitive to vancomycin. Conclusion CAP is quite common in elderly population in Chuzhou from 2010 to 2022, with a high prevalence rate in spring and winter, and the prevention work of high-risk groups should be strengthened.
