Reviewer:  Hang Viet Dao
Reviewer's report:
The manuscript is well written with the clear study aims and methods.
The situation of H.pylori infection in the family and risk factors relating to lifestyle is  very
important to consider how to prevent re-infection.
There are some minor comments for the authors to consider:
- Add on the questionnaires in the appendix of the manuscript
- For the Methods, can the authors clarify the specificity, sensitivity of fecal antigen test  using.
- For the Results, Table 2 have some metrics such as Percentage of family members tested for
H.pylori or with higher education seems confusing with median 0.19 and 0.54? I think it can
be explained in the results as text.
- The Figures now have some line graphs to illustrate the prevalence of H.pylori infection, the
authors can consider to change the style because it can make confusions about the change of
prevalence during time.
