transmitted infections (STI) are a group of contagious diseases which can be transmitted via unprotected sexual intercourse with an infected partner. The partner may not even know his/her infectious status.
The Sunday Morning Brunch spoke with Consultant Venereologist Dr. Sujatha Samarakoon, MBBS (Cey), MSc, MD, Dip GUM (Lond), FCCP (SL), to debunk myths and misconceptions surrounding STIs in order to disseminate accurate information.
Sexually transmitted infections (STI) can arise due to bacteria, parasites, yeast, and viruses, and there are more than 20 different types. Among them, those infected with HIV (Human Immunodeficiency Virus) face greater stigma than others.
What’s most prevalent in Sri Lanka?
- The most prevalent STI in Sri Lanka is genital herpes virus infection followed by genital warts caused by the human papillomavirus
- Bacterial infections such as gonorrhea and chlamydia are also prevalent in Sri Lanka
- Syphilis, which is caused by a bacteria, is showing a declining trend
According to Dr. Samarakoon, the highest reports of STIs are among those aged 25-49 years. However, she said there might be a reporting bias as the current statistics were from government STD services and statistics do not include those attending private health services for treatment of STIs.
How does one get treatment?
- Government-run clinics offer free and high-quality services
- Younger patients prefer to attend private clinics
- Younger people are at greater risk as many engage in risky sexual behaviour
She also pointed out that younger individuals are more prone to succumb to peer pressure and experimentation, where they may have unprotected (condom-less) sex, thus increasing the risk of contracting STIs, including HIV.
She explained risky behaviour as engaging in unprotected sex with casual or commercial partners where you buy or sell sex, having sex with multiple partners, and frequently changing partners. These sexual encounters could be vaginal or anal.
She emphasised the importance of a thorough medical check-up, including a physical examination from a qualified doctor.
There are nearly 35 full-time government STD clinics located islandwide from where any person is able to get a full check- up for STIs free of charge while maintaining confidentiality.
The importance of early treatment
Some people develop symptoms after a long period following contact with the infection, similar to the herpes infection, genital warts, and HIV. However, one must keep in mind that they can still be infectious even before the symptoms start to emerge
- Infections such as gonorrhea and chlamydia in males is symptomatic, presenting itself with a purulent urethral discharge
- In females, both these infections affect the cervix or the neck of the womb and most often they are asymptomatic
- Use of alcohol and illicit drugs catalyse risky sexual behaviour
Dr. Samarakoon also mentioned that early treatment will certainly prevent complications. For example, in females, infections such as gonorrhea and chlamydia affect the cervix and if not treated correctly and early, may spread to the fallopian tubes and lead to infertility and at times even cause an ectopic pregnancy.
Similarly, in males, some STIs can cause infertility. She further emphasised on how to protect oneself if sexually active and that it lies entirely in the hands of the individual.
The best practice is to avoid sex with casual partners and refrain from buying or selling sex, and if these are not possible, consistent and correct condom use provides some protection.
Seeking medical advice immediately after a risky sexual encounter is another important factor as some STIs can be treated completely if prompt treatment is given, she said.
- Human papillomavirus (HPV) is the causative agent for genital warts and high-risk HPV strains are responsible for causing cervical cancer
- The best way of prevention is to be vaccinated against HPV and it has to be administered before the sexual debut
- The Government of Sri Lanka has introduced the vaccine to the National Immunisation Programme and in government schools, girls aged 10 are vaccinated for HPV
- Girls attending private schools can avail themselves of this service through the medical officer of health of the respective geographical area
Finally, Dr. Samarakoon concluded with her one take-home message: Avoid risky sexual behaviour which puts you at risk of STIs/HIV and lead a healthy and productive life, she said.
