Epidemiology of chickenpox in Agona West Municipality of Ghana

Abstract

Chickenpox cases in recent time have increased in Agona West Municipality. The study showed that chickenpox is persistent in the municipality with R₀ = 2. The stability analysis of disease free and endemic equilibrium point of chickenpox transmission without vaccination was estimated to be a centre. Chickenpox in the Municipality can be prevented by reducing the rate at which people are exposed to the disease. Sensitivity analysis of the SEIR model showed that the latency rate was more sensitive to the model than the transmission rate (b) and the recovery rate (g).
