“…Our study showed an opposite picture, whereby there was a very low seroprevalence rate of HAV and a moderately high rate of H. pylori . Our study is similar to many other studies [17–19,26–30] in that H. pylori and HAV were not significantly associated. This adds further proof that H. pylori and HAV do not share a common transmission route and source as previously believed.…”

“…The association of serum antibodies against H. pylori with serum antibodies against two known waterborne pathogens hepatitis A virus [18] and Giardia [19] suggests that the infection may be waterborne or related to poor sanitary practices [20]. Klein et al [21] studied the prevalence of H. pylori infection in 407 children (two months to 12 years old), in Lima, Peru.…”

Helicobacter pylori infection in human is one of the most common infections worldwide. However, the origin and transmission of this bacterium has not been clearly explained. One of the suggested theories is transmission via water. This study was conducted to determine the prevalence rate of H. pylori in tap water, dental units' water, and bottled mineral water in Iran. In the present study, totally 200 water samples were collected in Isfahan province and tested for H. pylori by cultural method and polymerase chain reaction (PCR) by the detection of the ureC (glmM) gene. Using cultural method totally 5 cultures were positive. Two out of 50 tap water samples (4%), 2 out of 35 dental units' water (5.8%) samples, and 1 out of 40 (2.5% ) from water cooler in public places were found to be contaminated with H. pylori. H. pylori ureC gene was detected in 14 (7%) of water samples including 5 tap water (10%), 4 dental units' water (11.4%), 1 refrigerated water with filtration, and 4 (10%) water cooler in public places samples. This may be due to the coccoid form of bacteria which is detected by PCR method.

“…Since H. pylori is transmitted from person-to person suggesting fecal to oral transmission, 18 several investigators have studied a possible link between seropositive H. pylori and HAV. [19][20][21] In our study, HAV seropositivity was significantly higher in the H. pylori-positive group suggesting the possible association between both infections. The socioeconomic status is presumed to play an important role in H. pylori infection, 22 which was one of the associated factors with HAVseropositivity in our study.…”

Background/Aims: An epidemiologic shift of hepatitis A virus (HAV) seroprevalence is expected due to an improvement in socioeconomic status in young adults in Korea. We investigated the age-specific seroprevalence and socioeconomic factors associated with HAV seropositivity in young, healthy Korean adults. Methods: Between March 2009 and February 2010, a total of 5,051 persons from 20 to 49 years of age presenting for a health check-up were included and responded to a questionaire. The seroprevalence of HAV was investigated by measuring immunoglobulin G (IgG) anti-HAV. A total of 984 pairs of cases and age-and sex-matched controls were analyzed for associated socioeconomic factors. Results: The prevalence of seropositive HAV was 6.2% in the 20 to 29 age range, 33.1% in the 30 to 39 range and 82.4% in the 40 to 49 range (p<0.001). There were no signifi cant differences in any group according to gender. A multivariate analysis for paired cases indicated that HAV seropositivity was signifi cantly higher in the low monthly income (below fi ve million won, approximately 4,300 dollars) group and the Helicobacter pylori (H. pylori)-positive group (odds ratio [OR], 1.65; 95% confi dence interval [CI], p<0.001; OR, 1.45; 95% CI, p<0.001, respectively). Conclusions: HAV seropositivity in young adults presenting for a health checkup appears to be decreasing, and the prevalence was signifi cantly higher in the low monthly income group and the H. pylori-positive group.

Association between hepatitis A virus and Helicobacter pylori in a developing country: The saga continues

Abstract: The low number of subjects negative for both H. pylori and HAV antibodies in Lebanon is indicative of their high prevalence in the country. It is possible that this high prevalence reflects an age-specific prevalence rather than a true association.
