I read the publication with a great interest . It is interesting to recognize the ideas of the pets' owners regarding possiblity of COVID-19 during outbreak. Whether the pet can get infection and whether there is an intertransmission of disease between pet and owner are important issue in public health. At present, there are evidences only infection in some patients who own pets and detection of virus in some pets  but there is still a lack for proof for disease transmission process from owner to pet or pet to owner. At noted by Watson et al., the diagnosis is very important. The important consideration of diagnosis is the sample collection and quality of the diagnostic test. The difference of background condition betrween animal and human beings might cause possible diffrerent on diagnositc property of the diagnostic test kit. The human based diagnostic test kit might be limited aplied for animal diagnosis.
