Evolution of SARS-CoV-2 and Diagnostic Techniques For COVID-19
The historical evolution of all coronaviruses and to accompany viral epidemics, as well as COVID-19 diagnostics in the twenty-first century are looked at.
Evolution of RNA viruses from SARS to SARS-CoV-2 and diagnostic techniques for COVID-19: a review
The history, evolution of all coronaviruses and the associated viral outbreaks along with the diagnostics for COVID-19 in the twenty-first century is explored and special attention is given to SARS-CoV-2, its genome updates, and infectivity.
Diagnostic approaches in COVID-19: clinical updates
A narrative and critical review on different technology-based diagnostic strategies of COVID-19 including real-time reverse transcriptase PCR, serological testing through enzyme-linked immunosorbent assay, laboratory and point of care devices, and radiology-based detection through computed tomography and chest X-ray are performed.
Arsenal of microfluidic testing devices may combat COVID-19 pandemic
The first publications on SARSCoV-2 identified it as an RNA-based virus of the order Nidovirales, the family Coronaviridae, and the genus Betacoronavirus, and it was determined to be similar to other aggressive strains, such as the Severe Acute Respiratory Syndrome coronavirus (SARS-CoV) and the Middle East Respiratories Syndrome coronvirus (MERS- coV).
University participation in the production of molecular diagnostic tests for the novel coronavirus in Brazil: the response to health challenges.
The current study proposes to identify and reflect briefly on the rapid implementation of an initiative by the Brazilian scientific community in Molecular Biology to perform COVID-19 molecular
The New Coronavirus COVID-19 Infection
This review summarizes the relevant information about the origin and spread of SARS-CoV-2, its epidemiology and diagnostics, and the clinical course and treatment of COVID-19.
Microfluidic devices for the detection of viruses: aspects of emergency fabrication during the COVID-19 pandemic and other outbreaks
In this work, the most recent publications on microfluidics devices for the detection of viruses are reviewed and approaches such as electrochemical analyses, field-effect transistors and resistive pulse sensors are considered.
Currently Used Diagnostic Techniques for The Detection of SARS COV-2 Coronavirus
The procedures to be adopted for the diagnosis of COVID-19 should be based not only on clinical but epidemiological agents also and anyways stand on the link to an assessment and likelihood of the infection.
SARS-CoV-2 Subgenomic N (sgN) Transcripts in Oro-Nasopharyngeal Swabs Correlate with the Highest Viral Load, as Evaluated by Five Different Molecular Methods
It is worthy of note that the detection of the sgN transcript is associated with a higher viral load, thus representing a new marker of early and more severe infection.
Differences in innate Intracellular viral suppression competencies may explain variations in morbidity and mortality from SARS-CoV-2 infection.
The result suggests that differential ZAP activity may be a major determinant of the outcome of SARS-CoV-2 infection and suggests that asymptomatic patients may paradoxically shed a more dangerous virus.
