Dear Colleagues,

The translational value of research findings in animal models is sometimes questioned. Nevertheless, in the ongoing SARS-CoV-2 pandemic, animal models represent an indispensable component of transmission and vaccine studies. Without these studies, there is a realistic chance that there would have been no vaccine available yet. As new variants of concern emerge, and more data become available about disease manifestations outside the respiratory tract and delayed recovery of persons infected by SARS-CoV-2, the role of research and animal models is still highly relevant. In these studies, imaging, from all different kind of perspectives not only medical imaging but also pathology or for instance whole body plesmathography, is a non-invasive tool widely used in both human and veterinary research and medicine, which enables qualitative and quantitative characterization of the disease over a longer period. Imaging has proven to be a powerful method in characterizing and monitoring SARS-CoV-2. With this Special Issue, we invite researchers to contribute with articles describing the features of SARS-CoV-2 in different animal models using different imaging techniques. We also welcome papers addressing the manifestation of disease outside the respiratory tract. Moreover, considering that we are dealing with an infection which can cause long-term symptoms both after a mild and severe disease process, there is a special interest in research investigating and visualizing long COVID or post-acute sequelae of SARS-CoV-2.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Veterinary Sciences is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
