STIs without a clear source: risks and misunderstandings

A common question in the world of sexual health is whether you can get an STI if your partner does not have one. This article explores the possibilities and misunderstandings surrounding the transmission of STIs in relationships where one partner is seemingly STI-free.

Transmission of STIs: the basic concept

STIs are transmitted through sexual contact, including vaginal, anal and oral sex. Most STIs require at least one partner to be infected to be transmitted. However, there are some nuances and scenarios that make the answer to this question less straightforward.

Asymptomatic STIs and ignorance

Many STIs, including chlamydia and herpes, can be asymptomatic, meaning a person can be infected without any visible symptoms. This can lead to the false assumption that the partner is STI-free. Such asymptomatic cases pose a significant risk for the unconscious transmission of STIs.

Testing and window periods

Regular STI testing is crucial for sexually active individuals. However, the reliability of these tests can be affected by the window period - the time between infection and when the infection becomes detectable in tests. Thus, a recently infected person may test negative incorrectly.

Prevention and safe sex

Although the risk of STIs is significantly lower if both partners are tested and found STI-free, it is important to adopt safe sex practices. The use of condoms and regular STI testing play an important role in prevention, even in monogamous relationships.

Conclusion

While transmission of an STI is unlikely if both partners are STI-free, there are scenarios where transmission is possible due to asymptomatic infections or inaccurate test results. Regular STI testing, open communication about sexual health and safe sex practices are essential for reducing risks.
