The study investigated the important epidemiological parameters and farm-level economic costs of FMD incidence in cattle and buffaloes during 2013-14 to 2015-16 in various states of India. Multistage random sampling procedure was adopted for the primary survey and data was collected through face-to-face personal interview from 18,609 cattle and buffalo rearing farm households from 123 districts across twelve states and one Union Territory. Besides epidemiological parameters, different farm-level direct and indirect loss associated with FMD was assessed at disaggregated level (states) by employing deterministic mathematical models. Highest number of affected villages and disease incidence was observed in non- FMD control programme (FMD-CP) implemented Madhya Pradesh and Assam states, respectively whereas negligible incidence was in FMD-CP implemented Punjab state. The disease incidence was high during 2013-14 and declined during 2014-15 and 2015-16, respectively implied severe incidence scenario (2013-14) succeeded by moderate (2014-15) and mild (2015-16) scenarios. The crossbred and high productive animals were severely affected than local breeds whereas on sexwise and agewise comparison revealed higher incidence in females and adult animals. During severe incidence scenario, milk loss/animal ranged from USD 6.87-47.44, 18.42-125.88, 16.33-91.43, and 27.17-123.62; mortality loss/animal ranged from USD 32.61-804.27, 30.76-577.7, 65.36-502.2, and 188.04-413.7; distress sale loss/animal ranged from USD 3.22-188.63, 64.34-519.3, 214.47-341.8, and 209.11-450.3; and opportunity cost of labour/animal from USD 5.49-54.29, 5.49-67.78; 7.95-31.37 and 9.83-72.38 in indigenous cattle, crossbred cattle, local and improved buffalo, respectively. The estimated draught power loss/animal varied from USD 39.46-142.94 with least being in Madhya Pradesh and highest in Assam states whereas the median treatment cost/animal was USD 9.18 and USD 27.07 in indigenous cattle and upgraded buffaloes, respectively. The total farm-level economic loss projected due to FMD in cattle and buffaloes in India was USD 3159 million (INR 221,110 million), USD 270 million (INR 18,910 million) and USD 152 million (INR 10,610 million), respectively during the severe, moderate and mild incidence scenarios at 2015-16 constant prices. The loss varied across the states, and in severe incidence scenario, the country might lose USD 3.2 billion/year and hence, the bi-annual vaccination schedule need to be strictly implemented in all the states. Besides timely vaccination coverage, managing unabated animal movement, educating and motivating the farmers to vaccinate their animals might reduce the incidence and consequential losses to various stakeholders in endemic states like India.
本研究调查了 2013-14 年至 2015-16 年期间印度各邦牛和水牛口蹄疫发病的重要流行病学参数和农场层面经济成本。采用多阶段随机抽样程序进行初步调查,并通过面对面的个人访谈从印度 12 个邦和 1 个联邦属地的 123 个区的 18609 个养牛和养水牛的农户中收集数据。除了流行病学参数外,还通过使用确定性数学模型在州一级评估与口蹄疫相关的不同农场层面的直接和间接损失。在未实施口蹄疫控制计划(FMD-CP)的中央邦和阿萨姆邦,受影响的村庄和疾病发病率最高,而在实施 FMD-CP 的旁遮普邦,发病率则较低。2013-14 年的疾病发病率较高,2014-15 年和 2015-16 年分别下降,表明严重发病情况(2013-14 年)之后是中度(2014-15 年)和轻度(2015-16 年)发病情况。杂交牛和高产品种牛比本地品种牛受影响更严重,而在性别和年龄方面的比较表明,雌性和成年动物的发病率更高。在严重发病情况下,每头动物的牛奶损失/动物范围为 6.87-47.44 美元、18.42-125.88 美元、16.33-91.43 美元和 27.17-123.62 美元;每头动物的死亡损失/动物范围为 32.61-804.27 美元、30.76-577.7 美元、65.36-502.2 美元和 188.04-413.7 美元;每头动物的紧急销售损失/动物范围为 3.22-188.63 美元、64.34-519.3 美元、214.47-341.8 美元和 209.11-450.3 美元;每头动物的劳动力机会成本/动物范围为 5.49-54.29 美元、5.49-67.78 美元、7.95-31.37 美元和 9.83-72.38 美元,分别适用于本地牛、杂交牛、本地和改良水牛。每头动物的役用畜力损失/动物范围为 39.46-142.94 美元,其中最低的是中央邦,最高的是阿萨姆邦。每头动物的中位数治疗费用/动物为 9.18 美元和 27.07 美元,分别适用于本地牛和改良水牛。2015-16 年,印度牛和水牛因口蹄疫造成的农场层面经济总损失预计为 3.159 亿美元(2211.0 亿印度卢比)、2.7 亿美元(189.1 亿印度卢比)和 1.52 亿美元(106.1 亿印度卢比),分别处于 2015-16 年的严重、中度和轻度发病情况。损失因邦而异,在严重发病情况下,印度每年可能损失 32 亿美元,因此,所有邦都需要严格执行双年度疫苗接种计划。除了及时接种疫苗外,管理不受限制的动物流动,教育和激励农民为其动物接种疫苗,可能会降低在印度等口蹄疫流行邦的各种利益相关者的发病和后续损失。
