(a) The trend of hospital-acquired methicillin-resistant Staphylococcus aureus-infected individuals \(\left({H}_{I}\right)\) cases. The graph demonstrates that according to the constructed model, hospital-acquired methicillin-resistant Staphylococcus aureus cases indicate an increasing trend for 30 years with a start date of early 2023 followed by a plateau of up to 800 cases. (b) The trend of hospital-acquired methicillin-resistant Staphylococcus aureus-infected individuals \(\left({H}_{I}\right)\) cases with control. The graph demonstrates that according to the constructed model with optimal control, hospital-acquired methicillin-resistant Staphylococcus aureus cases indicate an increasing trend starting from the earliest of 2023 followed by a plateau with up to 650 cases.
