Regions with high gastric cancer in

Regions with high gastric cancer incidence rate tend to have
high seroprevalence rates for H. pylori infection. However,
there are geographical regions, such as Africa and South Asia
(e.g. India), where the seroprevalence rates for H. pylori infection
are high but the gastric cancer incidence rates are low. This
phenomenon has been dubbed the Asian or African enigma,(3,31)
and is probably a reflection of the complex host, bacterial and
environmental factors at play in gastric carcinogenesis. It has
also been suggested that disease manifestation reflects the
predominant pattern of gastritis within a geographical region, and
that the main factor is the interaction of host and environmental
factors such as diet, and not the bacterial strain.(3)

胃癌高发生率的地区往往有高血清阳性反应率为幽门杆菌的感染的。然而，有地理区域，如非洲和南亚（如印度），在那里血清阳性反应率幽门杆菌的感染高但胃癌发病率很低。这现象被称为亚洲或非洲 enigma,(3,31)可能是反映了复杂的主机，细菌和环境因素在胃癌发生过程中发挥作用。它有也是疾病表现反映了胃炎一个地理区域内的主要模式和主要因素是主机与环境的相互作用饮食和没有发现细菌感染等因素。(3)

胃癌发病率高的地区往往有幽门螺杆菌感染的血清阳性率高。然而,有地理区域，如非洲和南亚（如印度），在幽门螺杆菌感染的血清阳性率但胃癌发病率低。这现象被称为亚洲或非洲的谜，（3、31）并可能反映了复杂的宿主，细菌和胃癌发生中的环境因素。它有也有人认为，疾病的表现反映了地理区域内胃炎的主要模式主要因素是宿主与环境的相互作用因素，如饮食，而不是细菌菌株。（3）
