Sexually transmitted infections of the tongue

It is often mistakenly believed that sexually transmitted infections (STIs) can only affect the genitals. However, it is also possible for certain STIs to infect other parts of the body. For example, an STI transmitted through unprotected oral sex can lead to an infection of the tongue. Luckily, oral STI tests can provide clarity and peace of mind. Chlamydia, gonorrhoea, herpes, syphilis, and HPV are all STIs that can infect the mouth or tongue.

Red dots on the tongue - cause for concern?

Could you have an STI? Red dots or sores on the tongue can be caused by many things, including syphilis and herpes. Oral chlamydia or gonorrhoea do not cause sores on the tongue, but can cause a sore throat, difficulty swallowing, and enlarged lymph nodes. You can read more about chlamydia in our blog “How long does chlamydia last?” If you’ve been experiencing any of the above symptoms, have had unprotected oral sex, or have been warned by a partner that they have an STI, you may want to consider an oral STI test from Homed-IQ. This test checks for chlamydia and gonorrhoea using a swab sample. You will receive the results of your STI test within 2 days of receipt of the sample at the laboratory.

Chlamydia in the throat

Chlamydia can enter the mouth or throat through unprotected oral sex, such as oral sex without a condom or dental dam. Chlamydia in the throat is rarer than STIs in other parts of the body. In other words, you are less likely to have chlamydia in the throat/mouth area than, for example, a chlamydia infection in the genital area. However, chlamydia in the throat often does not cause any symptoms, which is why diagnosis in this part of the body is less frequent than in the genital area. As symptoms may not be present, getting tested is the most reliable way to rule out an oral STI. 

Normally, an oral chlamydia infection does not cause any symptoms. However, the following complaints may occur; Sore throat, pain when swallowing, swollen glands in the throat, and fever.

Gonorrhoea in the throat

Gonorrhoea can also infect the throat and is more common than oral chlamydia. While less common than genital gonorrhoea, performing unprotected oral sex on someone with gonorrhoea can transmit the infection, just as receiving oral sex from someone with an oral gonorrhoea infection can. During an oral infection, it is possible that a gonorrhoea test sample from the anus, vagina, or penis is negative, while you still have a gonorrhoea infection in the throat.

Most people with oral gonorrhoea have little to no symptoms, although the most common symptom is a persistent sore/itchy throat. Other symptoms can include difficulty swallowing, flu-like symptoms, swollen or painful glands, or redness in the throat.
