What are the most common sexually transmitted diseases or STDs in Spain?

In Spain, despite its advanced health system, it is not exempt from sexually transmitted diseases. Below we show you the 1st most common diseases in our country.


Chlamydia tops the list of the most common STDs in Spain. This bacterial infection usually does not present visible symptoms, but it can cause serious complications in the reproductive system if not treated in time. The use of condoms helps prevent it.


Gonorrhea is another prevalent STD in Spain that affects the genital organs, rectum and throat. Symptoms include painful urination, abnormal discharge, and pelvic pain. If left untreated, it can cause fertility problems. Safe sex and regular testing are essential to control its spread.

Human papilloma virus

HPV is a common viral STD worldwide. This virus causes genital warts and increases the risk of developing cervical cancer, among others. Vaccination and the use of condoms are important to avoid this infection.

Genital herpes

It is a chronic viral infection that causes painful sores on and around the genitals that may come and go periodically. The virus can be transmitted even when there are no visible symptoms. Although there is no cure, antiviral medications can reduce the frequency and severity of outbreaks. Open communication with partners and using condoms can help prevent its spread.


Syphilis is a bacterial STD that presents symptoms in stages from painless ulcers on the genitals, rash all over the body, to involvement of internal organs such as the heart and brain. It can be treated with antibiotics and regular testing is essential to diagnose it early.

HIV is a virus that attacks the immune system and can lead to AIDS, a condition that severely weakens the body's ability to fight infections. Although medical advances have improved the prognosis of HIV, there is still no cure. It can be prevented with the use of condoms and regular testing.

Hepatitis B

Hepatitis B is a viral infection that affects the liver. It can be transmitted through contact with infected body fluids, including unprotected sexual intercourse. This disease can be chronic and cause serious liver problems. Getting vaccinated is the best way to protect yourself against it.

Hepatitis C

Like B, hepatitis C is a viral infection that affects the liver and can be transmitted sexually. There are no symptoms until the disease is advanced, so early detection and treatment are crucial to prevent it.

Bacterial vaginosis

Common infection in women. Its symptoms are abnormal vaginal discharge and unpleasant odor. Although not strictly classified as an STD, unprotected sex increases the risk of getting one. Consulting a health professional for a proper diagnosis is essential.
