Summary

Helicobacter pylori (H. pylori) is a common infection linked to peptic ulcers and gastric cancer. This review examines H. pylori transmission routes and risks for healthcare workers, especially endoscopists.

Area of Science:

  • Microbiology
  • Gastroenterology
  • Infectious Diseases

Background:

  • Helicobacter pylori is a prevalent human pathogen, strongly associated with peptic ulcer disease.
  • Emerging evidence links H. pylori infection to the development of gastric cancer.
  • Understanding H. pylori transmission is crucial for infection control in healthcare settings.

Purpose of the Study:

  • To review the transmission routes of Helicobacter pylori.
  • To assess the occupational risk of H. pylori infection for hospital staff, particularly endoscopists.
  • To synthesize current evidence on H. pylori transmission and healthcare worker risk.

Main Methods:

  • Literature review of epidemiological studies.
  • Analysis of evidence regarding H. pylori transmission pathways (faecal-oral, oral-oral).
  • Evaluation of studies reporting on the risk of H. pylori infection in healthcare professionals.

Main Results:

  • Contradictory evidence exists regarding the increased risk of H. pylori infection for endoscopists.
  • Reported risks range from no significant increase to a five-fold higher incidence.
  • Faecal-oral and oral-oral routes are the primary suspected modes of H. pylori spread.

Conclusions:

  • Healthcare workers, especially those performing endoscopy, may be at risk of H. pylori exposure.
  • Further research is needed to clarify the exact occupational risks associated with H. pylori.
  • Effective infection control measures are essential to minimize transmission in clinical environments.
