Helicobacter pylori is a gram-negative spirochete that causes chronic gastritis. Helicobacter pylori can exist everywhere in the patient's digestive system, from the oral cavity, stomach, esophagus, duodenum, and colon. However, Hp bacteria usually live in the stomach and colon more often.

Since the bacteria Helicobacter pylori (H. pylori) was discovered by two Australian medical scientists, R Warren and B Marshall in 1982 and officially published evidence that H. pylori bacteria are capable of causing gastritis in a journal. Medical journal The Lancet in 1983, so far, there have been thousands of medical studies related to H. pylori bacteria in human pathology have been published.

Helicobacter pylori infection is one of the most common bacterial infections in the world, second only to tooth decay bacteria. Helicobacter pylori is the main cause of chronic stomach pain such as peptic ulcers, even stomach cancer. So is HP virus contagious, and in what ways?

Currently, the number of people infected with gastric HP bacteria is increasing. This is one of the causes of stomach ulcers and stomach cancer.

Helicobacter pylori (HP) is a gram-negative, flagellated spirochete found in and beneath the mucosal layer of the gastric epithelium. HP can survive in the acidic environment of the stomach. This bacterium secretes the enzyme urease, which helps neutralize stomach acid.

Stomach cancer is the third leading cause of death in the world. There are many factors that increase the risk of this disease. Accordingly, helicobacter pylori infection was assessed as highly likely. Therefore, screening and monitoring endoscopy to detect Helicobacter pylori bacteria is essential, especially for people with a family history of stomach cancer.
