Mathematical epidemiology of HIV/AIDS in cuba during the period 1986-2000

| Summary: | The dynamics of HIV/AIDS epidemics in a specific region is de-termined not only by virology and virus transmission mechanisms, but also byregion's socioeconomic aspects. In this paper we study the HIV transmissiondynamics for Cuba. We modify the model of de Arazoza and Lounes [1] accord-ing to the background about the virology and the socioeconomic factors thataffect the epidemiology of the Cuban HIV outbreak. The two main methodsfor detection of HIV/AIDS cases in Cuba are ''random'' testing and contacttracing. As the detection equipment is costly and depends on biotechnologicaladvances, the testing rate can be changed by many external factors. Therefore,our model includes time-dependent testing rates. By comparing our model tothe 1986-2000 Cuban HIV/AIDS data and the de Arazoza and Lounes model,we show that socioeconomic aspects are an important factor in determiningthe dynamics of the epidemic. |
