# Chlamydia: All You Need to Know
Chlamydia is one of the most common sexually transmitted infections (STIs) worldwide. It’s often silent, highly transmissible, and easily treatable—*but only if you know you have it*. Because most people experience no symptoms, chlamydia is frequently passed unknowingly between partners. Understanding how chlamydia spreads, how it presents, how to test for it, and how it’s treated is essential for protecting your own health and the health of your partners. This guide provides a clear, science-based, and supportive overview for anyone who believes they may be at risk or simply wants to stay informed. ---
What Is Chlamydia?

It can infect: - The penis - The vagina - The cervix - The urethra - The rectum - The throat - The eyes (less common) Chlamydia spreads through unprotected **vaginal, anal, or oral sex**, and can also be transmitted from mother to baby during childbirth. ---
How Common Is Chlamydia?
- It’s the **most commonly reported bacterial STI** in many countries, including the U.S., U.K., Australia, and New Zealand. - Young adults aged **15–29** carry the highest rates due to biological vulnerability and higher partner turnover. - Because symptoms are rare, many people only discover it through routine screening or after a partner tests positive. ---
Symptoms of Chlamydia
### **Most people have *no symptoms*** Around **70–90%** of women and **50%** of men show no symptoms.
