Sep 23, 2020 · The size of SARS-CoV-2 ranges from 0.07 μm to 0.09 μm [23,24]. The following calculations of the minimum sizes of particles containing SARS-CoV-2 are based on the assumption of a homogeneous distribution of viruses inside respiratory fluid particles, with a maximum size of 0.09 μm (sphere, d virus) for SARS-CoV-2. In addition, a spherical ...
Data are accumulating that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19, is transmitted by both small and large particle aerosols. These data suggest that health-care workers should be protected from these potentially infectious aerosols when working in close proximity to patients.

Oct 6, 2020 · The RBM mediates contact with the ACE2 receptor (amino acids 437–507 of SARS-CoV-2 S protein), and this region in SARS-CoV-2 differs from that in SARS-CoV in the five residues critical for ACE2 ...

Apr 2, 2020 · The COVID-19 pandemic is a harsh reminder of the fact that, whether in a single human host or a wave of infection across continents, viral dynamics is often a story about the numbers. In this article we provide a one-stop, curated graphical source for the key numbers (based mostly on the peer-reviewed literature) about the SARS-CoV-2 virus that ...

Apr 24, 2020 · Aerosols as virus delivery systems. The new coronavirus, SARS-CoV-2, is tiny, about 0.1 microns - roughly 4 millionths of an inch - in diameter.
May 19, 2020 · Zhu and colleagues noted that SARS-CoV-2 virions ranged from “about 60 to 140 nm”. In another recent study, virus-like particles in patients with confirmed SARS-CoV-2 infection were 70–110 nm in diameter. By comparison, SARS-CoV-1 viral particles analysed with the same technique (ultrathin EM imaging) were 50–80 nm in diameter.
