Fig. 1From: Modelling the impact of correlations between condom use and sexual contact pattern on the dynamics of sexually transmitted infectionsExample of the construction of next generation matrix. Based on the next generation matrix without any intervention, K, next generation matrix with condo use, K′ was constructed. As an example, the illustration of \( {K}_{4,2}^{\hbox{'}}\left(={K}_{f_2,{m}_2}^{\hbox{'}}\right) \) is shown. This element describes the transmission from men with a single partner to women with a single partnerBack to article page
