LetterCOVID-19: Time to exonerate the pangolin from the transmission of SARS-CoV-2 to humans.
The emergence of COVID-19 has triggered many works aiming at identifying the animal intermediate potentially involved in the transmission of SARS-CoV-2 to humans. The presence of SARS-CoV-2-related viruses in Malayan pangolins, in silico analysis of the ACE2 receptor polymorphism and sequence similarities between the Receptor Binding Domain (RBD) of the spike proteins of pangolin and human Sarbecoviruses led to the proposal of pangolin as intermediary. ⋯ Moreover, data available do not fit with the spillover model currently proposed for zoonotic emergence which is thus unlikely to account for this outbreak. We propose a different model to explain how SARS-CoV-2 related coronaviruses could have circulated in different species, including humans, before the emergence of COVID-19.

The Early Effects of Coronavirus Disease-2019 on Head and Neck Oncology and Microvascular Reconstruction Practice: A National Survey of Oral and Maxillofacial Surgeons Enrolled in the Head and Neck Special Interest Group.
The coronavirus disease-2019 (COVID-19) pandemic has affected healthcare systems across the nation. The purpose of this study is to gauge the early effects of the COVID-19 pandemic on head and neck oncology and reconstructive surgery (HNORS) practice and evaluate their practice patterns especially ones that might be impacted by COVID-19 and compare them to the current literature. ⋯ The COVID-19 pandemic had a small impact on the surgical treatment of patients with head and neck oncology. Most HNORS surgeons are practicing in accordance with recently published literature.
