Matlab code for Model parameters Estimation

I am working on Lassa Fever I have my Model Equations but from the reported data on Lasa fever, I have only confirmed cases and death case recorded. Please, is the two data enough to obtain the parameters?2. I need the Matlab code to estimate my parameters Thanks

Here is the model equations for the model

I refer you to: Parameter Estimation for a System of Differential Equations (use the later code in the Comments for best results). If you have only two variables (confirmed cases and deaths) to fit, you will have to choose the appropriate columns to return as ‘Cv’. I cannot determine how successful you will be at fitting all the parameters with so few data. Also consider using ode15s instead of ode45 in the event that your system of differential equations is‘stiff’ with parameters of significantly-varying orders-of-magnitude.
