What is the probability of mouth-to-mouth transmission of Helicobacter pylori?

Patient's question:

Today, I was chatting with a colleague (this colleague also has a bad stomach, often feeling bloated and pressure, and has not undergone thorough examination or treatment, nor does he know if he is infected with HP). His saliva, in the form of droplets, landed on my mouth! At that time, I didn't swallow! I wiped it off with my finger and then licked my lips with my tongue, spitting out some saliva! Later, I looked up information and found that HP can be transmitted through droplets! I want to know what the chance of getting Helicobacter pylori from saliva is?

Doctor's answer:

The chance of getting infected with Helicobacter pylori during a chat is very low, because Helicobacter pylori lives in the stomach and is usually spread through the digestive tract. If your stomach isn't doing well, you should pay attention to your diet. If you don't pay attention to your diet, it's easy to get sick. Besides getting timely treatment for Helicobacter pylori, patients should always maintain a positive attitude towards the disease. Only in this way can they reduce their immunity and the belief to fight the disease. At the same time, they should pay more attention to their own dietary care, focus on balanced nutrition, and digest the nutrients in the body in a timely manner.
