江苏省连云港市2008—2017年结核病流行状况

Objective: To investigate the prevalence and development of pulmonary tuberculosis(PTB) in Liangyungang, 2008- 2017 and we provide references for PTB surveillance and control in Liangyungang. Methods: We collected epidemic information of PTB in Lianyungang from 2008 to 2017, and used retrospective epidemiological methods to describe and analyze the epidemic situation of PTB. Results: From 2008 to 2017, 21 472 cases of PTB were reported in Lianyungang, annual average reported incidence rate (48.29/100 000) and average annual incidence rate of pathogenic positive patients (21.06/100 000) showed a trend of decline year by year（P<0.01）. The morbidityof PTB was higher in November, December and March, while in January, Februaryand October were lower（P<0.01）. Guannan County has the highest incidence rate and Haizhou District has the lowest, the morbidity in the county level was significantly higher than that in the urban area according to the cumulative incidence in the past ten years (P<0.01). The average age was (50.18±19.62) yrs, the obvious high-incidence age group was 20 -<30 and 50 -<70. Among 21 472 cases, 16 725 patients (77.90%) were farmers, 1 234 (5.75%) were housekeeping, 1 052 (4.90%) were students, and 11.47% were other occupations; there were 15 913 males and 5 559 females, sex ratio between men and women was 2.86∶1, 231 cases (1.08%) were migrating population, 21 422 cases (99.77%) were Han nationality, 12 cases (0.06%) were Mongolian nationality, and other minorities accounted for 0.17%. Among the sources of patients, the majority population was due to symptoms (51.04%) and referral (42.84%), proportion of negative etiology was higher (56.12%).The majority were primary treatment (87.35%) and non-severe cases (88.23%), 93.67% of the patients were under the course of treatment and cured. The average wind speed was positively correlated with the reported incidence of PTB (r =0.256，P<0.05). The linear regression equation between average wind speed and monthly morbidity is Y=2.650 + 0.303X. Conclusion: The reported incidence of PTB in Lianyungang has been decreasing over the past ten years, and the prevention and control should be further strengthened. © 2020 China Tropical Medicine.
