The widespread of HIV/AIDS has continued to constitute serious health and socioeconomic challenges for more than two decades, especially in sub-Saharan Africa. A permanent cure for this pandemic is not yet established and the issue of abstinence or faithfulness to sexual partners seems to be very difficult. This study used Genetic Agorithm of Soft Computing Framework for Modelling Transmission Dynamics of HIV/AIDS under combined use of male and female condoms in heterosexual populations of Taraba State. A total of 761 questionnaires were distributed to HIV/AIDS patients in the three senatorial zones of Taraba State. The researcher identified four set of terminals as independent variables: Never used condom, Used condom occasionally, Used condom most of the time, and Used condom all of the time. These values were converted to binary and coded as chromosomes into three fold: Male use of condom, Female use of condom, and Male and Female use of condom. The coded chromosomes of each category formed set of target values into the simulation of the Genetic algorithm. The simulation revealed that eradication of HIV/AIDS is obtainable in 6 generations with the use of male condom, 4 generations with the use of female condom and 2 generations with the use of both male and female condoms. The study also revealed that 56.4% of the respondents were female, 34.6% were male, 61.23% never used condom and 22.34% used condom all the times. This shows that there is no awareness on the use of female condom in Taraba State and probably the neighbouring states or Nigeria at large. The study recommended, among others, the use of both male and female condoms together as the best measure to achieve HIV/AIDS eradication in finite time.Keywords: Genetic Algorithm, HIV/AIDS transmission, Male and Female Condoms, Soft computing, Taraba StateVol. 26, No. 1, June 2019

In this paper, a nonlinear mathematical model is presented for the transmission dynamics of HIV/AIDS in Cuba. Due to Cuba's highly successful national prevention program, we assume that the only mode of transmission is through contact with those yet to be diagnosed with HIV. We find the equilibria of the governing nonlinear system, perform a linear stability analysis, and then provide results on global stability.

A sex-structured staged progression model for heterosexual transmission dynamics of HIV/AIDS in a community to theoretically assess the effects of gender parameter accounting for population heterogeneity is formulated and analyzed. The basic model without this parameter is analyzed, and then extended to include gender heterogeneity in order to explore its role on the transmission dynamics of the disease. Mathematical properties including epidemic thresholds known as reproductive numbers are derived. The models are numerically analysed using some demographic and epidemiological parameters for Zimbabwe. These simulations suggest that the use of identical gender attributes simplifies computation at the expense of reality as it underestimates the size of the epidemic by 5%. This study demonstrates that the use of gender related parameter in the transmission dynamics of HIV gives a better estimate of the prevalence of the epidemic and should be given prominence.
