In this paper, we establish a ZIKV model and investigate the transmission dynamics of ZIKV with two types of harvesting: proportional harvesting and constant harvesting, and give the stability of the steady states of both disease-free and endemic equilibrium, analyze the effect of harvesting on ZIKV transmission dynamics via numerical simulation. We find that proportional harvesting strategy can eliminate the virus when the basic reproduction number R₀ is less than 1, but the constant harvesting strategy can control the virus whether R₀ is less than 1. Epidemiologically, we find that increasing harvesting may stimulate an increase in the number of virus infections at some point, and harvesting can postpone the peak of disease transmission with the mortality of mosquito increasing. The results can provide us with some useful control strategies to regulate ZIKV dynamics.

采收后寨卡病毒的传播动力学

在本文中，我们建立了一个ZIKV模型，研究了ZIKV在两种收获方式下的传播动态：比例收获和恒定收获，并给出了无病和地方性平衡稳态的稳定性，分析了收获的效果ZIKV传输动力学的数值模拟。我们发现，当基本繁殖数R ₀小于1时，比例收获策略可以消除病毒，而恒定收获策略可以控制病毒是否为R ₀小于1。从流行病学的角度来看，我们发现收获的增加可能会在某个时候刺激病毒感染数量的增加，并且收获可以随着蚊子死亡率的增加而推迟疾病传播的高峰。结果可以为我们提供一些有用的控制策略来调节ZIKV动态。
