Control of sexually transmitted infections and prevention of HIV transmission: mending a fractured paradigm

In many countries, basic STI services are in disarray as programme resources are determined by decisions relating to a single disease entity. Such a fractured paradigm is as counterproductive for HIV as it is for other STIs. Major HIV epidemics emerged from and spread rapidly under conditions of poor STI control, and further weakening of STI control may well undermine other HIV prevention efforts.

Effects of periodic presumptive treatment on three bacterial sexually transmissible infections and HIV among female sex workers in Port Moresby, Papua New Guinea.

BACKGROUND:

Sexually transmissible infections (STI) are common in female sex workers (FSW).

AIM:

To determine if 3-monthly periodic presumptive treatments (PPT) would reduce the prevalence of STI in FSW.

Using mathematical modelling to estimate the impact of periodic presumptive treatment on the transmission of sexually transmitted infections and HIV among female sex workers.

 

In settings with poor sexually transmitted infection (STI) control in high-risk groups, periodic presumptive treatment (PPT) can quickly reduce the prevalence of genital ulcers, Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT). However, few studies have assessed the impact on HIV. Mathematical modelling is used to quantify the likely HIV impact of different PPT interventions.

Periodic presumptive treatment of curable sexually transmitted infections among sex workers: recent experience with implementation.

 Curable sexually transmitted infections (STIs) are common occupational hazards for female sex workers in low-income and middle-income countries. Yet, most infections are asymptomatic and sensitive screening tests are rarely affordable or feasible. Periodic presumptive treatment (PPT) has been used as a component of STI control interventions to rapidly reduce STI prevalence.
