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 the World Health Organization (WHO) in the first quarter of 2020. The delay in diagnosis, limited hospital resources , and other treatment resources lead to the rapid spread of COVID-19. In this article, we consider a dynamical model and analyze the impact of some control measures that can lead to the reduction of exposed and infectious individuals of the transmission of COVID-19 . We investigate four control strategies diagnosis and spraying the environment to curb the transmission dynamics of the novel virus .
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 .
