title: [Study on influence of floods on bacillary dysentery incidence in Liaoning province, 2004 -2010].
abstract: OBJECTIVE
  To understand the influence of floods on bacillary dysentery in Liaoning province.
  
  
  METHODS
  The monthly surveillance data of bacillary dysentery, floods, meteorological and demographic data in Liaoning from 2004 to 2010 were collected. Panel Poisson regression analysis was conducted to evaluate the influence of floods on the incidence of bacillary dysentery in Liaoning.
  
  
  RESULTS
  The mean monthly morbidity of bacillary dysentery was 2.17 per 100 000 during the study period, the bacillary dysentery cases mainly occurred in during July-September. Spearman correlation analysis showed that no lagged effect was detected in the influence of floods on the incidence of bacillary dysentery. After adjusting the influence of meteorological factors, panel data analysis showed that the influence of floods on the incidence of bacillary dysentery existed and the incidence rate ratio was 1.439 4(95%CI: 1.408 1-1.471 4).
  
  
  CONCLUSIONS
  Floods could significantly increase the risk of bacillary dysentery for population in Liaoning.
