So it’s cause for concern that South Africa, with — 7,9 million people living with HIV in 2017 — also has a high volume of STIs.
In 2017, there were an estimated 2,3 million new cases of gonorrhoea, 1,9 million new chlamydia cases and 23 175 new syphilis cases among women aged between 15 and 49.
Among men of the same age there were an estimated 2,2 million new cases of gonorrhoea, 3,9 million new cases of chlamydia and 47 500 new cases of syphilis.
These high numbers of STI cases in South Africa have partly been due to inadequate prevention and treatment gaps.
Some people with STIs such as chlamydia, may go untreated because they don’t show any symptoms.
Better STI screening for high-risk clients — regardless of symptoms — and better training of healthcare workers is necessary.
In addition, structural problems such as limited access to client-friendly STI detection and treatment services need to be addressed.
Of course, all of this costs money, which is in short supply. That’s why the need for better prevention cannot be overstated.
STI prevention in the past
Prevention of STIs other than HIV has largely taken a backseat while the country focused on HIV prevention.
HIV prevention concentrated on reducing the number of sexual partners people have, increasing the correct and consistent use of condoms, early detection and treatment, and promotion of male circumcision.
These measures were of some benefit in preventing other STIs.
But the increasing availability of antiretroviral drugs and advances in research have brought a new message to people living with HIV: An HIV-positive person, with an undetectable viral load, can’t transmit the virus to their HIV-negative partner.
This message, however, does not directly address the transmission of STIs other than HIV.
It focuses on HIV and how to manage it, but forgets that people with HIV may be vulnerable to other STIs.
Pre-exposure prophylaxis — another HIV prevention tool — involves taking antiretroviral medication to prevent HIV infection.
Research has shown that, if taken consistently and as intended, it can reduce the risk of acquiring HIV.
But pre-exposure prophylaxis doesn’t protect people from other STIs.
Services to test for and treat STIs are included in pre-exposure prophylaxis services as a way of assessing levels of unprotected sex and sexual risk taking, among users.
But the take home message about the prevention of STIs in these settings is not clear.
What counselling on STIs are pre-exposure prophylaxis clients receiving or should they be receiving?
How should pre-exposure prophylaxis be promoted without compromising STI prevention?
Renewed focus on STI prevention
Strategies to prevent STIs must take into account the changes and advances in HIV prevention and treatment.
Policies must answer a number of questions.
For instance, how can having fewer sexual partners, the correct and consistent use of condoms, the early STI detection and treatment of oneself and one’s partners, and male circumcision be made “fashionable” when HIV is not the death sentence that it used to be?
And what’s the best way to communicate that the knowledge of infections in oneself and the partner are key to preventing both HIV and other STIs?
It’s also important to explore how best to design prevention services that communicate how STIs and HIV happen in the context of transient, short-term or longer relationships.
Policymakers need to understand, too, how people could be empowered to form, maintain or terminate relationships in a manner that does not place them in harm’s way with respect to HIV, STIs or intimate partner violence.
All of these issues must be urgently considered if South Africa is to tackle its STI problem as effectively as it’s been able to deal with HIV. — The Conversation
