Gonorrhea is caused by Gram negative bacteria Neisseria gonorrhoeae, also known as gonococcus. It is a sexually transmitted infection (STI). Gonorrhoea has been referred to as the “clap” in history.
Transmission of gonorrhea
Gonococcus is present in the discharge from the penis and vaginal fluid of the infected men and women. Routes of transmission of infection include:
- It can be passed from person to person by having unprotected vaginal, oral or anal sex
- It can also be transmitted by sharing sex toys and vibrators with an infected individual without washing or covering them with a condom at each use
- Gonococcus can be transmitted from a pregnant woman to her baby
Incubation period
The incubation period is usually taken as being between 2 and 5 days but may be up to 10 days. Incubation period is the time taken from exposure to the infection and appearance of the symptoms.
