H. Pylori Infection - Diagnosis and Prevention

Helicobacter pylori is a bacteria that is commonly present in stomach lining causing ulcers. This infection is contagious and it spreads from one person to another due to poor maintenance of personal hygiene. It spreads through saliva and fecal contamination of food and water.
