Vaccination is the most effective and safe preventive strategy against many childhood infectious diseases. We can vaccinate effectively and safely against potentially lethal and debilitating diseases including measles, mumps, influenza, smallpox, tuberculosis, Rubella, poliomyelitis, and various other diseases. However, there are still outbreaks where vaccination is not available and increasingly in the era of contrarian thinking where vaccines are not taken as an option by some parents for their children, we are seeing the re-emergence of epidemics of these horrendous diseases.
Now, mathematician Kazeem Oare Okosun of Vaal University of Technology, in Gauteng, and Oluwole Daniel Makinde of Stellenbosch University, South Africa, have derived and analysed a deterministic model for the transmission of childhood disease perform optimal control analysis of the model. Writing in the International Journal of Computing Science and Mathematics, they report on how a disease might be controlled optimally to reduce the devastating impact of an epidemic. Their approach also looks at how financial costs might be minimized in efforts to control a childhood disease.
