HPV and HIV co-infection poses a significant public health challenge, especially in regions with high prevalence of these infections. HPV is known to cause cervical cancers, while HIV weakens the immune system, increasing susceptibility to opportunistic infections and cancers.

To better understand the co-evolution dynamics of these two diseases, a study was conducted through the construction of a dynamic co-infection model. The developed model tracks the evolution of infected epithelial cells into precancerous and cancerous states. Mathematical analysis revealed that co-infection accelerates the progression of infected epithelial cells towards precancerous and cancerous states. However, combined treatments, including antiretroviral therapies and HPV vaccines, can slow this progression, offering promising prospects for more effective treatment strategies.

The mathematical model developed in this study provides a better understanding of the dynamics of HPV/HIV co-infection. It can serve as a basis for designing more effective treatment strategies aimed at preventing progression to cancer. These results highlight the need for a multidisciplinary approach to combat these infections and their complications.
