Reviewer response for version 1
Well written paper on an important and largely ignored subject: ‘health workers perspectives for guidelines’; 
Also on top global health issue ‘Ebola virus disease’. 
Study process was speedy and appropriate for the urgency needed for guidelines to be developed making this a good learning experience. 
However, there are a few points of attention listed below. 
I have also highlighted the sections relevant to my comments here .
Methods
AQ1:
‘The 2014–2016 EVD outbreak in West Africa was initially declared a Public Health Emergency of International Concern in early August 2014, coinciding with the decision to develop a WHO rapid advice guideline on the selection and use of PPE for EVD care in outbreaks.’
This statement will fit more within the background section, consider moving into background.
AQ2:
‘We electronically surveyed international frontline physicians and nurses who participated in foreign medical teams deployed to the affected countries in early stages of the EVD outbreak.’
Clearly stating time frame in the methods section within which survey was done will also be helpful for readers, although a time frame is given later under participants, it is not clear if this was for survey or the sampling. 
this time frame is also very early in the outbreak
AQ3:
Settings is not well described, consider discussing setting in more detail under a separate title.
Results
AQ4:
Clinicians express discomfort and safety, it may be interesting to know if at some point in the interviews they weighed in on safety versus comfort e.g. will the feeling of safety make them cope with discomfort? 
Or does discomfort make safety inconsequential?
