摘要

本文提出了考虑免疫和康复或治疗等治疗干预措施的COVID-19传播机制的数学模型。该模型表明,当有效繁殖数小于或大于1时,无病平衡点和地方性平衡点是全局渐近稳定的。关键的疫苗接种阈值取决于疫苗预防或治愈疾病的能力。该模型基于疫苗接种效率、计划和社会措施放松等因素来预测疫苗接种的有效性。随着接种疫苗的实施,疫情的消退取决于放松社会措施的程度。

A simulation Model of COVID-19 Epidemic Based on Vaccination and Treatment
This article presents a mathematical model of the COVID-19 transmission mechanism, considering therapeutic interventions like immunization and recovery or treatment. The model shows that the disease-free and endemic equilibriums are globally asymptotically stable when effective reproduction numbers are less than or larger than unity. The critical vaccination thresholddepends on the vaccine’s ability to prevent or cure the illness. The model predicts the effectiveness of vaccination based on factors like vaccination efficiency, scheduling, and relaxation of social measures. The subsiding of the epidemic as vaccination is implemented depends on the scale of relaxation of social measures.
