在巴基斯坦信德省、旁遮普省和伊斯兰堡首都直辖区进行了一项纵向研究，以评价口蹄疫对养牛和水牛的农民的奶产量的影响。样本包括50个农场，最初根据临床症状怀疑存在口蹄疫病毒，随后通过实地测试或实验室确认得到证实。在每个农场，登记临床病例总数，并对临床患病的泌乳牛和水牛进行随访，从出现临床症状和测量产奶量开始，随访时间为60天，平均产奶量在口蹄疫发病前估计为每头牛10升左右，在急性临床疾病发病后的2个月内显著下降。在出现临床症状后的60天内，牛和水牛的产奶量损失估计分别约为220升和201升。假设接种与流行口蹄疫病毒相匹配的优质疫苗可以预防临床疾病，则在所有50个农场接种所有动物的效益/成本比估计为5.7。
A longitudinal study has been conducted in the provinces of Sindh, Punjab and Islamabad Capital Territory area, Pakistan, to evaluate the impact of foot-and-mouth disease on milk yield in a sample of farmers owning cattle and buffaloes. The sample consisted of 50 farms where the presence of foot-and-mouth disease (FMD) virus was initially suspected on the basis of clinical signs and subsequently confirmed through either a field test or laboratory confirmation. In each farm, the total number of clinical cases was registered, and clinically diseased milking cattle and buffaloes were followed up for the next 60 days from the onset of clinical signs and the amount of milk yield measured.The average milk yield, estimated to be around 10 l per animal before the onset of FMD, decreased significantly in the 2 months following the onset of acute clinical disease. The loss of milk production in the 60 days following the onset of clinical signs was estimated to be around 220 and 201 l for cattle and buffaloes, respectively. Under the assumption that the administration of a good-quality vaccine matching circulating FMD strains could protect against clinical disease, the benefit/cost ratio for having all animals vaccinated in all 50 farms was estimated to be 5.7.
