Expert elicitation on drivers used to assess the emergence of
COVID-19 in pets
An expert elicitation of knowledge was conducted, which consisted in
gathering the opinion of people with recognized scientific expertise
and/or experience in the field of COVID-19 in pets (Appendix
S3 ). For guidance purposes, an explanatory letter accompanied the
questionnaire that each expert had to fill out (Appendix S4 ).
The questionnaire was prepared as an Excel file based onAppendix S2 .
Each expert was contacted personally and responded individually to the
questionnaire. Data generated by the elicitation were based on the
individual values provided by experts in order to capture the degree of
variability of expert knowledge. The elicitation was performed from
24/04/20 to 15/05/20.
