臺灣地區家禽霍亂之發生

Occurrences of Fowl Cholera in Poultry Flocks in Taiwan

摘要


就1986年1月至1995年12月十年間臺灣地區680件家禽霍亂病例(包括鴨381件,雞255件)之發生情形進行時序分析,結果顯示台灣地區全年各月份均有家禽霍亂發生,且以七至八月間及十二月為主,其中在雞則以七月發生較多,三月則次之,至於鴨則以為八月較多,十至十二月次之。十年間雞在1989年7月與鴨在1989年9月及1990年5月報告件數顯著較多,顯示當時可能有家禽霍亂的大流行,又分析結果發現十年間臺灣地區家禽霍亂並未有周期性發生的現象,但有呈緩慢下降之趨勢,其中以雞下降最為顯著(P=0.0002)。

並列摘要


Fowl cholera (FC) was studied during a ten-year period (January1986through December 1995) in Taiwan. Total of 680 cases (including 381 duck cases and 255 chicken cases) were analyzed in a time series study. Peak seasonality for all cases was from July to August and in December, while duck cases peaked in August and November to December and chicken cases peaked in March and July. The cycle curve revealed two major epidemics in ducks (Sept. 1989 and May 1990) and one major epidemic in chicken (July 1989), with no apparent periodicity. By regression analysis, FC occurrence showed a slowly declined trend over ten-year period, especially in chickens (P=0.0002).
