SARS-CoV-2 in pets of infected family groups in a severely affected region in Spain

PURPOSE: The COVID-19 pandemic has caused an unprecedented health crisis with devastating effects. Current evidence suggests that SARS-CoV-2 could have an animal origin. Many uncertainties about the behaviour of the virus still persist, and understanding all the keys of this epidemic requires an interdisciplinary One Health approach spanning the human and animal health sectors. The closest coexistence between people and animals occurs in large cities. This study aims to identify the epidemiology (infection rate, risk habits, etc...) and evolution of the disease in pets that have coexisted during the confinement with family groups affected by the disease in areas of high population density and high disease incidence, i.e. Madrid. METHODS & MATERIALS: A network of veterinary clinics was created to provide sampling points for the pets. The family groups included both health workers from the collaborating hospitals and affected pet owners informed through the network of clinics. RESULTS: Epidemiological and clinical data were collected from 60 family groups and their pets. An epidemiological questionnaire and sample collection (oral and nasal swabs, faeces and blood) were carried out on each pet. The samples were analyzed by RRT-PCR and ELISA. Of the 55 pets analysed (17 cats and 38 dogs), 5 cats presented antibodies. This seroprevalence is in agreement with that shown by Patterson et al, 2020 in cats in Italy in highly affected areas. CONCLUSION: This study intends to extend the knowledge of the epidemiology and evolution of the disease in pets. This work was funded by a national project SANICOVID and international project JIP06-COVID19-COVRIN H2020.
