The epidemiological dynamics of chickenpox (varicella)
have been studied through mathematical models
especially in developed countries with emphasis on the
underlying process during the epidemic or endemic
period for varicella, the morbidity effects of immunization
against varicella and the seasonal variation in contact
rates (Giraldo and Palacio, 2008). However, few studies
have been done in developing countries like Ghana,
whose tropical climate, demographic pattern and socioeconomic
conditions can influence the dynamical
transmission of diseases.
