How is trich spread, and how can it be prevented?
Trich is spread when a person has unprotected sex with an infected partner. Some people carry the parasite that causes trich, but they do not have symptoms.

In rare cases, it may be possible to get trich from contact with personal items, such as a wet towel, that a person with trich has just used. The trich parasite cannot live on objects for long, so it isn't usually spread this way.
Trich may be spread from a mother to her baby during a vaginal delivery, but this is also rare.
Symptoms of a trich infection in young children may be a sign of sexual abuse. They need to be checked by a doctor.
