Figure 2. Incidence rates for cases of eosinophilic meningitis attributed to Angiostrongylus cantonensis infection, by period, Hawaii, January 2001–February 2005 (n = 24). The number over each bar indicates the number of cases during the period. The incidence rates (per 100,000 person-years) for the entire 50-month study period, the 46-month baseline period (January 2001–October 2004), and the 4-month cluster period were 0.5, 0.3, and 2.1, respectively.
