Table A.2.

Proportion of animals positive (as median and inter‐quartile range (IQR)) to SARS CoV‐2 infection in the field, per species and epidemiological unit following passive or active monitoring and according to virus detection/isolation or serological tests. Based on literature screening, only species found positive are included in the table, and studies including only one animal of this species are excluded from the calculations of proportions of positives
