The Review on Novel Coronavirus 2019

BACKGROUND Coronaviruses are group of enveloped viruses with positive sense RNA as the genetic material, containing 20-30kbp genome. These viruses cause mild respiratory and intestinal infections in immune compromised individuals. They were not considered to be pathogenic until the outbreak of Severe Acute Respiratory Syndrome (SARS) in china and Middle East Respiratory Syndrome Coronavirus (MERS-CoV) in Middle East countries in 2002 and 2012 respectively when the viral infection led to significant deaths among the infected individuals. The novel emerging pneumonic...

CORONAVIRUS (COVID-19) And Ventilators

Introduction COVID-19 is a worldwide pandemic involving the vast spread of a type of viruses called the Corona virus. These viruses are positive-stranded RNA viruses having a crown-like appearance when viewed an electron microscope. It belongs to the subfamily Orthocoronavirinae of the Coronaviridae family (order Nidovirales) and is divided into four genera of CoVs: Alphacoronavirus (alphaCoV), Betacoronavirus (betaCoV), Deltacoronavirus (deltaCoV), and Gammacoronavirus (gammaCoV). Then, the betaCoV genus divides into five sub-genera. Genomic studies have proven that bats and rodents are...

The Evolutionary Origins Of SARS-CoV-1, MERS-CoV And SARS-CoV-2

Abstract There are seven types of coronaviruses appeared till now and they are different in their pathogenicity and the degree of the severity of the symptoms they cause. Phylogenetic analysis should be conducted in order to know the origin of the lethal viruses to be able to find treatments for them. In this essay, what have been found so far about the evolutionary origins of SARS-CoV-1, MERS-CoV and SARS-CoV-2 will be discussed. Furthermore, the animal hosts that are similar to...

Immune Escape Strategies By Viruses

Introduction Viruses are considered as extremely successful predators as they can replicate and control the host cell synthesizing machinery. Viruses have coevolved with their hosts and thus have limited pathogenicity in any immunocompromised natural host. Viruses can exist in two forms: Extra cellular virion particles Intracellular genomes. Virions are more resistant to physical stress than genomes but are susceptible to humoral immune control. Nevertheless, to exist as a species, virus replication and transfer to a new host are essential. Virus...
