论文摘要
武汉（Wuhan）和中国其他城市的SARS-COV-2引起的Covid-19爆发已成为2020年第一季度世界卫生组织（WHO）所宣布的全球大流行。诊断，医院资源和其他治疗资源的延迟导致Covid-19的迅速传播。在本文中，我们考虑了最佳控制COVID-19传输模型，并评估某些控制措施的影响，这些措施可能导致人群中暴露和传染性个体的减少。我们使用人身保护，早期诊断治疗，延迟诊断和在环境中喷洒病毒作为时间依赖的控制功能，以遏制疾病扩散，以对环境中的延迟诊断和喷洒病毒的治疗进行三种控制策略。
The outbreak of COVID-19 caused by SARS-CoV-2 in Wuhan and other cities in China in 2019 has become a global pandemic as declared by World Health Organization (WHO) in the first quarter of 2020 . The delay in diagnosis, limited hospital resources and other treatment resources leads to rapid spread of COVID-19. In this article, we consider an optimal control COVID-19 transmission model and assess the impact of some control measures that can lead to the reduction of exposed and infectious individuals in the population. We investigate three control strategies for this deadly infectious disease using personal protection, treatment with early diagnosis, treatment with delay diagnosis and spraying of virus in the environment as time-dependent control functions in our dynamical model to curb the disease spread.
