Key result
~75% vaccination coverage proves sufficient to eradicate polio in mathematical simulations.
Why the study?
Despite global elimination initiatives, poliovirus transmission persists in various areas, highlighting the need for robust vaccination strategies.
A mathematical model suggests that approximately 75% vaccination coverage is sufficient to eradicate polio from the population.
May inform vaccination strategies in endemic areas; leaves open prospective validation before practice change.
Poliomyelitis, also known as polio, is a contagious viral illness that predominantly impacts young children, leading to paralysis and, in severe instances, death. Despite worldwide initiatives aimed at elimination, the spread of the poliovirus persists in various areas, highlighting the need for robust vaccination strategies. This research employed a mathematical model to explore the dynamics of poliovirus transmission, integrating vaccination as a crucial method for disease control. The model was analyzed to determine the basic reproduction number (R 0 ) and the stability properties of the disease-free and endemic equilibrium. Our findings demonstrated that the system achieves local asymptotic stability when the basic reproduction number is less than one, global asymptotic stability when it is exactly one, and maintains a stable endemic equilibrium when it is greater than one. Sensitivity analysis revealed critical parameters influencing the basic reproduction number, emphasizing the impact of vaccination coverage and disease transmission rates on polio dynamics. More so, numerical simulations showed that vaccination coverage of about 75% would be enough to eradication polio from the population.

Gul et al. (2026) studied Poliomyelitis. Vaccination coverage was evaluated on Basic reproduction number (R0) and disease eradication. Numerical simulations of the mathematical model demonstrated that a vaccination coverage of approximately 75% would be sufficient to eradicate polio from the population.
