为了了解传染病的动态和评估防治措施的效果,需要测量感染个体数的时间序列。但是,在鱼类疾病中,由于发病时的临床症状不明确和诊断费用等原因,通常难以记录感染鱼的时间序列。为了解决这个问题,我们建立了一个基于数学建模的方法来推断感染的鱼的数量的时间序列,通过耦合的实验感染和现场数据的疾病爆发。该方法能够使用从实验感染中获得的死亡率数据重建受感染鱼的数量的时间序列。重建的时间序列能够估计鱼病的传播。以虹鳟(Oncorhynchus mykiss)为模型,研究了虹鳟马苏病毒病(Oncorhynchus masouvirus,salmonid herpesvirus 2)的发病情况,并估算了虹鳟感染OMVD的致死率和基本繁殖数(R0),OMVD的传播性。结果表明,较大的鱼(≥200 g)与较小的鱼(<200 g)相比,具有较高的OMVD致死率和R0。这表明,与小鱼相比,大鱼的高死亡率并不能抑制病原体的传播。
Time series of the number of infected individuals is measured to understand the dynamics of an infectious disease and to evaluate the effectiveness of countermeasures against it. However, in fish diseases, it is often difficult to record the time series of the infected fish owing to i) ambiguous clinical symptoms during the onset of disease and ii) cost of diagnosis. To address this issue, we established a mathematical modeling-based method to infer time series of the number of infected fish by coupling the experimental infection and field data on the outbreak of the disease. This method enables to reconstruct time series of the number of infected fish using mortality data obtained from the experimental infection. The reconstructed time series enables to estimate the transmissibility of fish diseases. We studiedOncorhynchus masouvirus (salmonid herpesvirus 2) disease (OMVD) using Rainbow trout (Oncorhynchus mykiss) as a model for analysis and estimated the lethality rate of OMVD infection and the basic reproduction number (R0), i.e., transmissibility of OMVD. Our results revealed that larger fish (≥200 g) showed a higher OMVD lethality rate andR0s when compared with smaller fish (<200 g). This suggests that high mortality among large fish does not inhibit the transmission of pathogen when compared with small fish.
