Sexually transmitted infections, commonly known as stis, are among the most widespread health concerns worldwide. They are primarily transmitted through sexual contact, including vaginal, oral, and anal sex. While some infections can be easily treated, others may lead to long-term complications if left undiagnosed.
Understanding the different types of sexually transmitted infection conditions, their symptoms, and treatment options is essential for maintaining good sexual health. This guide covers the most common infections, what to watch for, and how to protect yourself.
What are sexually transmitted infections
Sexually transmitted infections are infections caused by bacteria, viruses, or parasites that spread through sexual contact. Some infections can also be transmitted through blood, from mother to child during pregnancy, or through shared needles.
Many people with stis do not experience noticeable symptoms, which makes regular testing and awareness extremely important.
Sexually transmitted infection symptoms
Symptoms can vary widely depending on the type of infection. In many cases, individuals may not notice any signs at all.
Common symptoms in both men and women
- Unusual discharge from the genitals
- Burning sensation during urination

- Itching or irritation
- Pain during sexual activity

Symptoms of STD in female
- Abnormal vaginal discharge

- Prevent long-term health complications
