Is it contagious to eat once with someone with gastritis

Gastritis is divided into infectious gastritis and non-infectious gastritis. Infectious gastritis is usually caused by Helicobacter pylori infection and can spread from person to person. If you eat or contact with people with infectious gastritis, it may increase the risk of infection. Non-infectious gastritis is usually caused by other factors, such as unreasonable diet, drug side effects, stress, etc. The above reasons are not infectious, and there is no transmission route, usually not infectious.
