Sexuality-based compartmental model of spread of HIV in the Philippines

Acquired Immunodeficiency Syndrome, (AIDS) a disease caused by the Human Immunodeficiency
Virus (HIV), is a sexually transmitted disease that first started spreading worldwide in the 1980s. As of today, there is no known cure and, as a result, prevention and public awareness are paramount in controlling HIV infection. The Philippines has historically had one of the fewest cases of HIV. However, data have shown an alarming increase in sexually transmitted HIV infections over the past few years. In this study, the spread of HIV among the heterosexual, bisexual and homosexual groups was modeled using a compartmental Susceptible-Infectious (SI) epidemic model. The results showed a significant increase in HIV infections among bisexual and homosexual groups in the Philippines since 2006.
