    Abstract

    Human behaviour is central to transmission of SARS-Cov-2, the virus that causes COVID-19, and changing behaviour is crucial to preventing transmission in the absence of pharmaceutical interventions. Isolation and social distancing measures, including edicts to stay at home, have been brought into place across the globe to reduce transmission of the virus, but at a huge cost to individuals and society. In addition to these measures, we urgently need effective interventions to increase adherence to behaviours that individuals in communities can enact to protect themselves and others: use of tissues to catch expelled droplets from coughs or sneezes, use of face masks as appropriate, hand-washing on all occasions when required, disinfecting objects and surfaces, physical distancing, and not touching one’s eyes, nose or mouth.

Perera, Leo L. M. Poon, John M. Nicholls, Malik Peiris & Hui-Ling Yen Nature (2020) Abstract SARS-CoV-2, a novel coronavirus with high nucleotide identity to SARS-CoV and SARS-related coronaviruses detected in horseshoe bats, has spread across the world and impacted global healthcare systems and economy1,2. A suitable small animal model is needed to support vaccine and therapy development. We report the pathogenesis and transmissibility of the SARS-CoV-2 in golden Syrian hamsters. Immunohistochemistry demonstrated viral antigens in nasal mucosa, bronchial epithelial cells, and in areas of lung consolidation on days 2 and 5 post-inoculation (dpi), followed by rapid viral clearance and pneumocyte hyperplasia on 7 dpi. Viral antigen was also found in the duodenum epithelial cells with viral RNA detected in feces. Notably, SARS-CoV-2 transmitted efficiently from inoculated hamsters to naïve hamsters by direct contact and via aerosols.
