title: [Epidemiological analysis on 141 cases of angiostrongyliasis cantonensis in Beijing].
abstract: OBJECTIVE
  To provide scientific basis for angiostrongyliasis cantonensis control and prevention in Beijing.
  
  
  METHODS
  Descriptive epidemiological method was used to analyze angiostrongyliasis cantonensis reported from June to September in 2006.

All patients had dined at the same restaurant in Beijing city and they ate undercooked Pomacea canaliculata or related eatables. The source of Pomacea canaliculata was from Guilin in Guangxi. Major manifestations would include fever (56.79%), headache (93.83%), neck stiffness (100%), and skin paresthesia (77.78%). Some cases had significant eosinophil increase in peripheral blood picture and cerebrospinal fluid respectively.
