What are the most common STIs?

There are many sexually transmitted diseases and infections. Some are not well known, but others are much more common. So what are the most common STIs? 

Genital herpes 

This is one of the most common STIs. It is highly contagious and affects both men and women between the ages of 15 and 49. It is a disease caused by the herpes simplex virus (HSV). Generally, genital herpes is asymptomatic. However, there are some symptoms that may indicate its presence. These include burning and itching sensations and the appearance of blisters on the genitals. 

These symptoms usually appear one week after unprotected sex. There are two types of herpes: HSV1 (herpes labialis) and HSV2 (genital herpes). Genital herpes, when detected early, can be treated with antiviral therapy. This treatment relieves the symptoms and cures the disease. The treatment must be done by the contaminating partner as well as the contaminated partner. 

Hepatitis B

The hepatitis B virus is also one of the most common sexually transmitted infections. It is highly contagious and is usually transmitted through sexual contact. This disease is more contagious and more serious than AIDS. Hepatitis B is a very serious infection. If it is not treated quickly, it can cause complications such as acute inflammatory liver damage. 

Symptoms of this infection include fever, fatigue, nausea, muscle pain and loss of appetite. To date, there is no effective treatment for the hepatitis B virus. Only the vaccine can protect you from this disease. 


Syphilis is a very common disease that affects mostly men who have sex with men (80% of cases). The symptoms of this disease usually appear two to four weeks after infection. 

These symptoms include a painless sore with a rash on the skin and mucous membranes. If detected early, syphilis can be treated with an intramuscular antibiotic injection.
