What is Trichomonas?

Trichomonas vaginalis is an infection caused by a microscopic parasite found in the vagina, and urethra in both women and men.

How is it passed on?

It is passed on through unprotected vaginal, oral or anal sex with an infected person, possibly by sharing sex toys, or from a mother to her baby at birth, or rarely by sharing moist towels, washcloths, hot tubs and Jacuzzis.


Signs and symptoms

Sometimes there are no symptoms, or they are so mild they go unnoticed.

Typical signs of infection include:

• A change in vaginal discharge: this may increase, become thinner, frothy or change in smell.
  
• A discharge from the penis.
  
• Inflammation, soreness or itching in and around the vagina.
  
• Pain on passing urine in both men and women.
  
• Pain on having sex.
  

Tests and treatment

• Usually a swab is taken from the urethra, vagina or tip of the penis. This might feel a bit uncomfortable but is quick and should not be painful.
  
• A sample of urine may be taken.
  
• Trichomonas vaginalis is easily treated with antibiotics. To avoid re-infection, sexual partners should also be treated.
  
• If left untreated it doesn't cause any serious health problems.

Long Term Effects

Usually none following treatment, but it's a good idea to have another check-up to make sure the infection is gone.
