Severe Acute Respiratory Syndrome

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. Over the next few months, 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 contained.

SARS or Severe Acute Respiratory Syndrome is a viral respiratory illness caused by a coronavirus - the SARS associated coronavirus (SARS-CoV) - which can be life-threatening.

Early tracheostomy could reduce recovery time in critical COVID-19, say researchers

A new study by researchers at the Northwestern University Feinberg School of Medicine, USA, reports the findings of a study on the safety of tracheostomy of critically ill patients and the feasibility of decannulation in most survivors. The researchers view this as a means to improve care in these patients

One in seven people in England show SARS-CoV-2 antibodies, finds study

The REal-time Assessment of Community Transmission-2 (REACT-2) program completed its fifth round of community surveys in the days between January 26 and February 8, 2021. The findings appear in a new article in the BMJ on February 25, 2021, showing that natural infection and vaccination together account for around 14% seropositivity rates in England at present.

New SARS-CoV-2 B.1.526 variant emerges in New York

New York has the first case of a new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant called B.1.526, picked up by genomic surveillance research from Columbia University. The findings come after reports of other variants have been reported worldwide — B.1.1.7 in the United Kingdom, B.1.351 in South Africa, and P.1/P.2 in Brazil.

Free-ranging minks exhibit high titers of SARS-CoV-2 antibodies in Utah

Researchers at the U.S. Centers for Disease Control and Prevention (CDC) report outbreaks of coronavirus disease (COVID-19) on mink farms in Utah, United States. They surveyed around farms for evidence of exposure and found high SARS-CoV-2 titers, suggesting a possible viral transmission pathway to native wildlife.

Time to implement measures preventing future viral zoonoses

Now, researchers at the University of Silesia in Katowice and the Poznan University of Medical Sciences in Poland recommend measures to prevent future zoonotic outbreaks. They emphasized the importance of viral surveillance and research on new viral strains as primary strategies to combat these infections.

SARS-CoV-2 modulates host cell central carbon metabolism for reproduction

A team of scientists from Sweden and India has recently characterized the host cell metabolic alterations associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Their findings reveal that SARS-CoV-2 modulates the host cell's central carbon metabolism to facilitate replication and infection propagation.
