How is Chlamydia Transmitted?

Chlamydia is primarily transmitted through sexual contact involving the exchange of infected bodily fluids. Here are the main routes of transmission:

1. Unprotected Sexual Contact

• Vaginal or Anal Intercourse: The most common transmission routes. The bacteria can infect the urethra, cervix, rectum, and throat .
• Oral Sex: Less common, but possible if one partner is infected .

2. Mother-to-Child Transmission

• Infected mothers can pass the bacteria to their newborns during childbirth, potentially causing eye infections (conjunctivitis) or pneumonia in the infant .

3. Rare Non-Sexual Transmission

• Although very rare, transmission can occur through contact with infected secretions (e.g., from the genitals or eyes) on hands or shared objects like sex toys .

Factors Facilitating Transmission

• Asymptomatic Nature: Up to 70% of women and 50% of men show no symptoms, unknowingly spreading the infection .
• Multiple Sexual Partners: Increases exposure risk.
• Inconsistent Condom Use: Not using condoms correctly during every sexual encounter significantly raises transmission risk .

Incubation period of chlamydia

 7 to 14 days
