Sexually transmitted co-infections increase HIV infectiousness through local inflammatory processes. The risk factors in acquiring genital co-infections associated with HIV infection still present many questions. There is some evidence that there is an association between certain sexually transmitted infections and HIV, but for others, there is only a marginal correlation, as will be discussed in this chapter. The most prevalent co-infections found in HIV carriers and their epidemiology, clinical features and evidence-based treatments will also be analyzed.
