What is sexually transmitted infections?
Sexually transmitted infections or STIs are infections that are spread during sexual contact with another person. According to the World Health Organisation (WHO) more than 1 million sexually transmitted infections (STIs) are acquired every day worldwide.1 More than 30 different bacteria, viruses and parasites are known to be transmitted through sexual contact. Eight of these organisms are linked to the greatest incidence of sexually transmitted disease in Africa and elsewhere.
Of these 8 infections, 4 are preventable and currently curable:
The other 4 are viral infections which are preventable but not curable:
STIs can have serious general and reproductive health consequences beyond the immediate impact of the infection itself.
So, how can you prevent catching STIs?
The only guaranteed method to prevent catching STIs is to abstain from all sexual contact. For most people this is not a practical remedy.
So, what to do? Prevention is the key and there are steps you and others can take to limit your risk of catching STIs.
Protection before sex
Effective STI prevention can be organized under two broad levels; the individual and public.
Individual protection
These are some steps to take in order to reduce your STI risk before having sex:
Public protection
Counselling and behavioural interventions offer the broadest public health efforts against STIs. According to the WHO, these efforts should include:1
Practicing safe sex
Engaging in safer sex practices implies using adequate and effective barrier products for all forms of sexual activities, except when planned child bearing is an objective. Reliable safe sex practices include:
Although washing off the genital skin area with soap and clean water after sex can help remove any infectious material on your skin, this is no guarantee against STI.
Vaginal douching by women immediately after sex should be avoided as this may precipitate widespread genital infections. Women should urinate after sex. This may help reduce the risk of urinary tract infections (UTI).
When used correctly and consistently, barrier products like condoms offer one of the most cost-effective methods of protection against STIs, including HIV, even if not 100% assured.
Correct use of barrier products
When using barrier products for safer sex, it’s important to follow the manufacturer’s instructions on the box and use them correctly.
Follow these safety precautions when using condoms:
Potential risks of barrier products
Although condoms and other barriers are effective at preventing the exchange of infected bodily fluids and minimising skin-to-skin contact, they do not totally prevent STI transmission. It is fool-hardy to think or believe so.
More so, if you’re in a sexual relationship with someone who has herpes, syphilis, human papilloma virus (HPV) or HIV, talk to your doctor about possibility of vaccination and/or pre-exposure prophylaxis. Such therapies help to prevent and reduce the risk of relevant viral infections and further transmission without providing cure of the infection.
Here are some reasons why male condom failure occurs
The estimated rate of male condom breakage is between 0.4% and 2.3%, while the rate of slippage is between 0.6% and 1.3%.2
