A number of different sexually transmitted diseases can lead to symptoms in the throat. Such STDs include chlamydia, gonorrhoea, syphilis and HIV. Congenital infection of human papillomavirus may lead to symptoms in the throats of children. If suspect STD symptoms appear--in the throat or elsewhere--it is important that the sufferer be tested to ensure that proper treatment measures can be taken.
Chlamydia can be found in the throat, where it can cause discomfort. Chlamydia can be transmitted to the mucous membranes of the throat through oral sex, most commonly when performed on a man. This is less common than transmission through vaginal or anal intercourse.
Oral gonorrhoea can lead to sore throat; however, most cases of oral gonorrhoea have no symptoms. It is possible to transmit oral gonorrhoea to the genitals of a partner and to contract oral gonorrhoea while performing oral sex.
Syphilis can lead to ulcerations of the mouth in both its primary, secondary and tertiary stages. In addition, syphilis may cause sore throat in the secondary stage.
Sore throat may appear as a symptom of acute HIV infection (first-stage HIV disease). In symptomatic HIV, the third stage of HIV disease, symptoms impacting the throat may include dry cough and breathing difficulty. Many of the infections found in people living with AIDS may impact the throat, including thrush, an oral fungus and Kaposi's sarcoma lesions (a type of skin cancer caused by infection with the virus HHV-8).
A pregnant woman infected with genital HPV can sometimes pass the infection to her child. This can lead to a condition known as recurrent respiratory papillomatosis, which, causes HPV warts in the throat and larynx.
