From the Guidelines
Helicobacter pylori is considered contagious and can spread from person to person through various routes, including oral-oral, fecal-oral, or gastro-oral transmission. The bacteria can be acquired during childhood, especially in areas with poor sanitation, overcrowded living conditions, or limited access to clean water 1. Key factors that contribute to the spread of H. pylori include:
- Poor hygiene practices
- Sharing of food, utensils, or drinking water
- Close living quarters
- Limited access to clean water and sanitation facilities
To prevent the transmission of H. pylori, it is essential to practice good hygiene, including:
- Regular handwashing with soap and clean water
- Avoiding sharing of eating utensils or food
- Ensuring access to clean drinking water
- Maintaining good sanitation and hygiene practices in daily life
If diagnosed with H. pylori infection, treatment typically involves a combination of antibiotics and proton pump inhibitors (PPIs) for 10-14 days, as single antibiotics are no longer effective due to increasing resistance 1. The standard treatment has evolved over time, with triple therapies using clarithromycin, metronidazole (or amoxicillin), and PPIs being widely used, although their effectiveness has declined due to increasing clarithromycin resistance 1. Eradicating H. pylori can cure gastritis and peptic ulcer disease and has the potential to prevent gastric cancer, making prompt treatment essential to improve patient outcomes and quality of life.

From the Research
Helicobacter pylori Contagiousness
- There are no direct research papers to assist in answering this question, as the provided studies focus on the treatment and eradication of Helicobacter pylori infection rather than its contagiousness.
- However, it can be inferred that Helicobacter pylori infection is typically spread through contaminated food, water, or close contact with an infected person 2, 3, 4, 5, 6.
- The exact mode of transmission is not explicitly stated in the provided studies, but it is known that Helicobacter pylori infection is a common cause of gastric-related diseases worldwide 2.
- Further research would be needed to determine the contagiousness of Helicobacter pylori and the most effective methods for preventing its transmission.
Treatment and Eradication
- The provided studies discuss various treatment regimens for Helicobacter pylori infection, including triple therapy with a proton-pump inhibitor, amoxicillin, and metronidazole (PAM) or clarithromycin (PAC) 2, 3, 5.
- Quadruple therapy regimens, such as amoxicillin/metronidazole/omeprazole/clarithromycin, have also been shown to be effective in eradicating Helicobacter pylori infection 6.
- The efficacy of these treatment regimens can vary depending on factors such as antibiotic resistance, patient compliance, and treatment duration 3, 5.
