If left untreated, H. pylori can lead to the development of stomach ulcers and inflammation. It is a known carcinogen and can eventually cause the development of stomach cancer.
Treatment often involves medical intervention that typically includes two antibiotics (amoxicillin and clarithromycin) and proton-pump inhibitors (PPIs).
Though not available yet, a vaccination is in development, which may help prevent the transmission of H. pylori in at-risk populations.
People planning short-term travel to areas with high incidence rates have a low risk of contracting the bacteria. More extended travel in certain areas holds a higher risk.
