| 5 | A mathematical modeling of rabies with vaccination and culling显示文摘Rabies is a fatal contagious disease but preventable.It is a major public health problem in developing countries.Most of the rabies deaths around the world are caused by dog bites.If a person does not receive appropriate treatment after being exploded to rabies,the virus can damage the brain resulting in death.Since most of the deaths due to the transmission from dogs to humans,therefore,in this study,we will formulate a mathematical model that describes the dynamics of rabies virus transmission between dogs and humans.Also,we conduct both epidemic and endemic analysis.Optimal control theory is applied to seek cost-effective solutions for time-dependent vaccination and culling strategies against rabies outbreaks.Our results show that using vaccination during rabies outbreaks at the very beginning of the onset and culling infected dogs can reduce the number of infections significantly. | Adison Thongtha Chairat Modnak | 2021 | International Journal of Biomathematics2021，14，6： | 0 |
| 6 | Optimal COVID-19 epidemic strategy with vaccination control and infection prevention measures in Thailand显示文摘COVID-19 is a severe acute respiratory syndrome caused by the Coronavirus-2 virus(SARS-CoV-2).The virus spreads from one to another through droplets from an infected person,and sometimes these droplets can contaminate surfaces that may be another infection pathway.In this study,we developed a COVID-19 model based on data and observations in Thailand.The country has strictly distributed masks,vaccination,and social distancing measures to control the disease.Hence,we have classified the susceptible individuals into two classes:one who follows the measures and another who does not take the control guidelines seriously.We conduct epidemic and endemic analyses and represent the threshold dynamics characterized by the basic reproduction number.We have examined the parameter values used in our model using the mean general interval(GI).From the calculation,the value is 5.5 days which is the optimal value of the COVID-19 model.Besides,we have formulated an optimal control problem to seek guidelines maintaining the spread of COVID-19.Our simulations suggest that high-risk groups with no precaution to prevent the disease(maybe due to lack of budgets or equipment)are crucial to getting vaccinated to reduce the number of infections.The results also indicate that preventive measures are the keys to controlling the disease. | Adison Thongtha Chairat Modnak | 2022 | Infectious Disease Modelling2022，7，4： | 0 |
