Monkeypox (MPX) is a zoonotic disease similar to smallpox. Its fatality rate is about 11% and it is endemic to the Central and West African countries. In this paper, we analyze a compartmental model of MPX dynamics. Our goal is to see whether MPX can be controlled and eradicated by voluntary vaccinations. We show that there are three equilibria-disease free, fully endemic and previously neglected semi-endemic (with disease existing only among humans). The existence of semi-endemic equilibrium has severe implications should the MPX virus mutate to increased viral fitness in humans. We find that MPX is controllable and can be eradicated in a semi-endemic equilibrium by vaccination. However, in a fully endemic equilibrium, MPX cannot be eradicated by vaccination alone.
猴痘（MPX）是一种类似于天花的人畜共患疾病。其死亡率约为11%，在中非和西非国家呈地方性流行。在本文中，我们分析了一个猴痘动态的分区模型。我们的目标是了解猴痘是否可以通过自愿接种疫苗来控制和根除。我们表明存在三种平衡状态——无病平衡、完全地方性流行平衡以及之前被忽视的半地方性流行平衡（疾病仅在人类中存在）。如果猴痘病毒发生突变，使其在人类中的适应性增强，那么半地方性流行平衡的存在将产生严重影响。我们发现，在半地方性流行平衡状态下，猴痘是可控的，并且可以通过接种疫苗根除。然而，在完全地方性流行平衡状态下，仅靠接种疫苗无法根除猴痘。
