Kollataj et al described the Parasitic Zoonoses Transmission Risk Score (PZTRS). This can help to identify a situation where the contact with pets can result in spread of parasites to humans. The authors are from Medical University Lublin, University of Life Sciences in Lublin, the University of Szczecin, and the Institute of Rural Health in Poland.
