Canine distemper virus (CDV) is endemic in Zambia, while peste-des-petits-ruminants virus (PPRV) has not been detected. This study screened 962 farmed goats and 237 small ruminants at informal markets for PPRV antibodies using c-ELISA. A subset (n = 29) was re-analysed with virus neutralisation assays (VNA) for antibodies to PPRV and CDV due to cross-reactivity concerns. c-ELISA indicated 6.44% PPRV seroprevalence on farms and 3.80% at markets. While VNA detected no PPRV antibodies, 45% (13/29) tested positive for CDV, possibly suggesting cross-reactivity. Given the study's limitations, further research is needed to determine whether PPRV is present in Zambia and assess potential cross-reactivity.
犬瘟热病毒（CDV）在赞比亚呈地方流行性，而小反刍兽疫病毒（PPRV）尚未被检测到。本研究使用竞争酶联免疫吸附测定（c-ELISA）对962只养殖山羊和237只在非正式市场的小反刍兽进行PPRV抗体筛查。由于存在交叉反应的担忧，对一个子集（n = 29）用病毒中和试验（VNA）重新分析PPRV和CDV抗体。c-ELISA表明农场中PPRV血清阳性率为6.44%，市场中为3.80%。虽然VNA未检测到PPRV抗体，但45%（13/29）的样本CDV检测呈阳性，这可能表明存在交叉反应。鉴于该研究的局限性，需要进一步研究以确定赞比亚是否存在PPRV并评估潜在的交叉反应。
