FAO联合国粮农组织：2001年第18期跨界动植物病虫害紧急预防系统跨界动物疾病通报（英文版）

Epidemiological data point towards the continued circulation of rinderpest in Pakistan. Rinderpest was detected on three occasions on intra-urban dairy farms in Karachi during the year 2000. These were the first confirmed outbreaks in Pakistan since the 1997 outbreaks in Punjab and they indicate that the rinderpest virus has circulated in Pakistan, despite an absence of disease detections for almost three years (see page 2).
