Hepatitis. Since all forms of hepatitis affect the liver, it naturally can be a life-threatening disease. Hepatitis A, B, and C can all be spread through sexual contact, and all can –– under the worst of circumstances –– lead to liver failure and death.
Deaths from sexually transmitted diseases (STDs) often occur long after acute infection, making their incidence difficult to estimate. Some infections, such as syphilis, may directly result in death. By contrast, human papilloma virus (HPV), HIV, and hepatitis more commonly cause death because of secondary sequelae.
The most dangerous viral STD is human immunodeficiency virus (HIV), which leads to AIDS. Other incurable viral STDs include human papilloma virus (HPV), hepatitis B and genital herpes.
For example, if left untreated, chlamydia and gonorrhea can make it difficult—or even impossible—for a woman to get pregnant. You also increase your chances of getting HIV if you have an untreated STD. Some STDs, like HIV, can be fatal if left untreated.
What is late-stage chlamydia? Late-stage chlamydia refers to an infection that has spread to other parts of the body. For example, it may have spread to the cervix (cervicitis), testicular tubes (epididymitis), eyes (conjunctivitis), or throat (pharyngitis), causing inflammation and pain.
Chlamydia is one of the most common STIs in women under 25 and is known as a “silent” infection, since most people never experience symptoms.
Tertiary Stage
Tertiary syphilis is very serious and would occur 10–30 years after your infection began. In tertiary syphilis, the disease damages your internal organs and can result in death.
Chlamydia (1+ years)
Because people infected with chlamydia often show no symptoms, it's sometimes called a “silent” infection. However, even when chlamydia is asymptomatic, it can spread during unprotected vaginal, oral, or anal sexual contact.
Gonorrhea has progressively developed resistance to the antibiotic drugs prescribed to treat it. Following the spread of gonococcal fluoroquinolone resistance, the cephalosporin antibiotics have been the foundation of recommended treatment for gonorrhea.
Herpes is easy to catch. All it takes is skin-to-skin contact, including areas that a condom doesn't cover. You're most contagious when you have blisters, but you don't need them to pass the virus along. Because herpes is a virus, you can't cure it.
The first well-recorded European outbreak of what is now known as syphilis occurred in 1494 when it broke out among French troops besieging Naples in the Italian War of 1494–98. The disease may have originated from the Columbian Exchange.
Viruses such as HIV, genital herpes, human papillomavirus, hepatitis, and cytomegalovirus cause STDs/STIs that cannot be cured. People with an STI caused by a virus will be infected for life and will always be at risk of infecting their sexual partners.
Human Papillomavirus (HPV) Infection
HPV is the most common STI in the United States, but most people with the infection have no symptoms. HPV can cause some health effects that are preventable with vaccines.
Adolescents, young adults, and men who have sex with men are at higher risk of getting STIs. And people who have an STI may be at higher risk of getting HIV. Promoting behaviors like condom use can help prevent STIs.
If syphilis is not treated, it can cause serious health problems, including neuralgic (brain and nerve) problems, eye problems, and even blindness. In addition, syphilis is linked to an increased risk of transmission of HIV infection.
If you have an incurable STI (like herpes, HIV, genital warts, and hepatitis B): These infections stick around in your body for life, but try not to panic — there are plenty of treatments that can help you live a healthy life, ease symptoms, and avoid passing the infection to other partners.
Visible sores (the primary stage)
These sores are very contagious and if you believe you may have syphilis sores you should avoid sex and get tested. They're usually firm and round, painless, and appear in the anus, on the penis, front hole, balls, or sometimes on or around the mouth.
There's no way to tell by looking if a person has an STD — even people who have STDs sometimes don't know it. If you have had sex before, you and your boyfriend can get tested together at a local health clinic like Planned Parenthood.
In a male, chlamydia can develop in the urethra, rectum, or throat. Some call chlamydia a “silent” infection because people are often unaware that they have it. The majority of these infections in males cause no symptoms.
Although chlamydia is highly contagious, it does not always transmit to a person's sexual partners. It is also possible to have a false-negative test result. Having more frequent sex with a partner who has chlamydia may increase a person's risk of contracting it.
Chlamydia is very common: it's the most frequently reported infectious disease in Australia, and nearly 97,000 men and women are diagnosed with it each year. If you're sexually active and under 30 years of age, you are at the highest risk of contracting chlamydia.
Men rarely have health problems from chlamydia. The infection can cause a fever and pain in the tubes attached to the testicles. This can, in rare cases, lead to infertility. Untreated chlamydia may also increase your chances of getting or giving HIV.
Symptoms in men
pain when urinating. white, cloudy or watery discharge from the tip of the penis. burning or itching in the urethra (the tube that carries urine out of the body)
