Parasites are micro-organisms which live in the intestines.
Some cause symptoms while others can live for long periods in the bowel without causing symptoms or requiring treatment. These symptoms may last for weeks and return several times a year. In North America and Europe, parasites rarely cause serious complications. If you are experiencing any of the above complaints, see your doctor. How you get it You can get parasites the same way you get hepatitis A , from oral contact anywhere in the anal area.
