The pandemic of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been posing great threats to the world in many aspects. Effective therapeutic and preventive approaches including drugs and vaccines are still unavailable although they are in development. Comprehensive understandings on the life logic of SARS-CoV-2 and ...
There are many variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID-19). Some are believed, or have been stated, to be of particular importance due to their potential for increased transmissibility, increased virulence, or reduced effectiveness of vaccines against them.
SARS-CoV-2 infection via airborne transmission of small particles tends to occur after prolonged exposure (i.e., >15 minutes) to an infectious person who is in an enclosed space with poor ventilation. 1. The risk of SARS-CoV-2 transmission can be reduced by covering coughs and sneezes and maintaining a distance of at least 6 feet from others.
We describe how SARS-CoV-2 may infect the lower respiratory tract and cause alveolar damage as a result of dysfunctional immune responses. We discuss how this may lead to the induction of a 'leaky state' of both the epithelium and the endothelium, promoting inflammation and coagulation, while an influx of immune cells leads to overexuberant ...
Severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) has spread rapidly throughout the world. SARS-CoV-2 is an enveloped, plus-stranded RNA virus with a single-stranded RNA genome of approximately 30,000 nucleotides. The SARS-CoV-2 genome encodes 29 proteins, including 16 nonstructural, 4 st …
Severe acute respiratory syndrome (SARS) is a viral respiratory illness caused by a coronavirus called SARS-associated coronavirus (SARS-CoV). SARS was first reported in Asia in February 2003. The illness spread to more than two dozen countries in North America, South America, Europe, and Asia before the SARS global outbreak of 2003 was ...
News. As SARS-CoV-2, the virus that causes COVID-19 in humans, continues to spread globally, questions have emerged about the potential for humans to transmit the virus to North American wildlife, its potential effects on native wildlife populations, and the resultant possibility and consequences of establishing a persistent wildlife reservoir.
SARS-CoV-2 is the novel coronavirus that causes COVID-19. It can be transmitted from infected individuals who never develop symptoms (asymptomatic), just before the onset of symptoms ...
SARS-CoV-2, the coronavirus that causes the disease COVID-19, is a big viral family with many variants. Just like with a human family tree, the distance between two variants shows roughly how ...
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant of concern belonging to the Pango lineage B.1.1.529, known as the Omicron variant, has spread rapidly worldwide (1,2). Several reports describe high infectivity and transmissibility of Omicron ( 3 , 4 ).
