Knowledge, Attitude, and Practices toward Hepatitis B Infection among Healthcare Students; A Nationwide Cross-Sectional Study in Jordan.

Comment: Thank you for this interesting article. I may have a few comments and questions toward improving this manuscript:
(1) In the abstract:

a) The first sentence relays a statement with data that is not included in the main manuscript. The abstract is a summary of the related article and whatever appeared within it should already be presented somewhere in the main text.

b) Authors may wish to write the full term of abbreviation (HBV) at its first occurrence.
c) Although optional it’d be better to format the abstract in the ‘structured’ style with sub-headings
(2) In the main body:

a) The rationale: As the authors mentioned that prevalence of HBV has notably dropped by 2016, the rationale and significance of this research should be boosted (with more details about national burden of HBV infection and its complications, epidemiological statistics about risk groups (particularly the study group). If there were a rise after the dropping of 2016, it would be a strong concern that warrants such research.

b) The target population and the definition of ‘healthcare students’: Although the authors put specific inclusion criteria, yet this does not make the study group fulfill the broad term ‘healthcare students’. A major problem with this is the unexplained exclusion of other important categories of students in fields of more or equally high risk such as those studying ‘Medical Laboratory Sciences’ and ‘Anesthesia’ among others. Some of the same universities have separate faculties teaching these students.
It is important to settle this issue because it undermines the claim of ‘this study surveyed the biggest sample of healthcare students …etc’ and may warrant modifying the Title (e.g. “…. Among Medical, Dental, Pharmaceutical and Nursing Students; A Nationwide…etc”) and/or in the least a mention in ‘Limitations’.
c) Kindly mention the study duration specifying the months and years.
d) Results: Selecting students who- through college- had completed (most probably 'successfully') a formal course related to viral hepatitis B, makes this research a testing and evaluation of the syllabus taught at these universities. The results should emphatically be linked to this context. Moreover, conclusions and recommendations have to strongly project this issue.
e) A correct categorization of the variable ‘Age’ is absent; and later in results interpretation just mentioning 'age' without hinting on which age favors the association. Subsequently the conclusion missed the mention of age.
f) The one-time mention of ‘Graduates’ is confusing and may need explaining. However, if it is meant to indicate ‘students who already graduated’ they may not be eligible for inclusion; and if it means ‘postgraduate students in the faculty’ then they should be in a separate category (not grouped with 6th year)
g) Kindly revise the sequence and order of numbering of the ‘Tables’ and their reference positions in the text throughout the manuscript. Some captions also need correction
h) Kindly write the full term of CDC then put the acronym in parentheses.
i) Kindly utilize paragraphing to divide the long blocks of text in all sections for better readability
3) References:

a) Kindly cite reference number 1 as “World Health Organization” or “WHO” (not “Organization, W.H.”).

b) Kindly check reference 4 to maintain consistency in formatting.
4) Extra questions:

a) Do all study disciplines (or Faculties) have a 6th year?

b) Is the syllabus of infectious diseases the same across all study faculties?
c) What about the other and private universities in Jordan that have faculties of medicine, pharmacy, nursing…etc?
Thank you
