On 11 March, some key industries in Wuhan were told they can resume, a day after Chinese President Xi Jinping visited the city for the first time since the outbreak began. Morphology Cross-sectional model of a coronavirus Coronaviruses are large pleomorphic spherical particles with bulbous surface projections.[10] The diameter of the virus particles is around 120 nm.[11] The envelope of the virus in electron micrographs appears as a distinct pair of electron dense shells.[12] The viral envelope consists of a lipid bilayer where the membrane (M), envelope (E) and spike (S) structural proteins are anchored.[13] A subset of coronaviruses (specifically the members of Betacoronavirus subgroup A) also have a shorter spike-like surface protein called hemagglutinin esterase (HE).[5] Inside the envelope, there is the nucleocapsid, which is formed from multiple copies of the nucleocapsid (N) protein, which are bound to the positive-sense single-stranded RNA genome in a continuous beads-on-a-string type conformation.[11][14] The genome size for coronaviruses ranges from approximately 27 to 34 kilobases.[7] The lipid bilayer envelope, membrane proteins, and nucleocapsid protect the virus when it is outside the host cell.[15] Replication The infection cycle of a coronavirus Infection begins when the virus enters the host organism and the spike protein attaches to its complementary host cell receptor. Teens and people in their 20s also encounter many others, at school and work and on public transit, yet they don’t seem to be contracting the disease at significant rates: Only 8. Here’s what scientists have learned about how the new virus infects and attacks cells and how it can affect organs beyond the lungs. There, the M proteins direct most protein-protein interactions required for assembly of viruses following its binding to the nucleocapsid.[21] Progeny viruses are then released from the host cell by exocytosis through secretory vesicles.[21] Transmission Human to human transmission of coronaviruses is primarily thought to occur among close contacts via respiratory droplets generated by sneezing and coughing.[22] The interaction of the coronavirus spike protein with its complement host cell receptor is central in determining the tissue tropism, infectivity, and species range of the virus.[23][24] The SARS coronavirus, for example, infects human cells by attaching to the angiotensin-converting enzyme 2 (ACE2) receptor.[25] Taxonomy Phylogenetic tree of coronaviruses The scientific name for coronavirus is Orthocoronavirinae or Coronavirinae.[2][3][4] Coronavirus belongs to the family of Coronaviridae.
