Abstract
Objective: To analyze the prevalence season and trend of meningococcal disease in China by epidemic years from 2004 to 2008 in order to provide scientific basis for making strategies ofmeningococcal disease prevention and control.
Methods: The incidence numbers of meningococcal disease were calculated by weeks, epidemic years and areas. The seasonality and prevalence trends of meningococcal disease were analyzed by circular distribution.
Results: The incidence trend of meningococcal disease had obvious seasonality in China (P < 0.01). The peak of meningococcal disease were different by epidemic years and areas (P < 0.01). There were no association between annual incidence rates and seasonality.
Conclusions: We should strength meningococcal disease surveillance before epidemic peak period,and put immunoprophylaxis first and carry out comprehensive measures of prevention and control.
