JOHNS HOPKINS UNIVERSITY The new, reportedly faster spreading strain of SARS-CoV-2, shouldn’t cause alarm, but does underscore the importance of following established prevention procedures, two experts say. In recent weeks, genetically divergent strains of SARS-CoV-2, the virus behind COVID-19, have been reported to be rapidly spreading in the United Kingdom, South Africa, and other nations,...

Unique susceptibility to unique Sars-CoV-2 variants and vaccines
by John Hewitt , Medical Xpress Credit: Wikipedia Individuals with different genetic variants in their immune system components often have very different immune responses to Sars-CoV-2. They also will have different responses to vaccines. By the same token, newly emerged variants in Sars-Cov-2 can elicit different immune responses in identical immune systems. In the larger...

Copper gluconate supplementation could reduce SARS-CoV-2 infection in vitro
By Dr. Liji Thomas, MD,Dec 16 2020 The second wave of the coronavirus disease 2019 (COVID-19) pandemic has affected many countries, costing thousands of lives and dealing further heavy blows to already reeling economies. Scientists have been working hard to bring out new drugs and repurpose older ones to stop the virus in its tracks...

Why COVID outbreaks look set to worsen this winter
It’s too soon to say whether COVID is seasonal like the flu — but where clusters aren’t under control, infections will continue to swell. Smriti Mallapaty Changing seasons might affect the transmission of SARS-CoV-2, but researchers say it’s too early to tell.Credit: Beata Zawrzel/NurPhoto/Getty Winter is fast approaching in the Northern Hemisphere, and researchers warn...

SARS-CoV-2 mutations do not appear to increase transmissibility
by University College London A colorized scanning electron micrograph of the SARS-CoV-2 virus. Credit: NIAID None of the mutations currently documented in the SARS-CoV-2 virus appear to increase its transmissibility in humans, according to a study led by UCL researchers. The analysis of virus genomes from over 46,000 people with COVID-19 from 99 countries is published...

Antibodies to SARS-CoV-2 are detected up to 3 months after infection
by Barcelona Institute for Global Health Coronavirus. Credit: European Centers for Disease Control A new study in health care workers led by the Barcelona Institute for Global Health (ISGlobal) shows that IgA and IgM antibodies to SARS-CoV-2 decay quickly, while IgG antibody levels are maintained for at least three months after infection. The longer follow-up of...

Monoclonal antibody HB27 shows potent neutralizing activity against SARS-CoV-2
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the causative pathogen of coronavirus disease 2019 (COVID-19) – has infected over 61.1 million people worldwide and caused over 1.43 million deaths. As scientists continue to probe for effective pharmaceutical interventions against SARS-CoV-2, a new study reports a very promising monoclonal antibody, HB27, that appears to have...

Immune-evading variants can emerge in SARS-CoV-2, researchers warn
By Sally Robertson, B.Sc.,Nov 9 2020 An international team of researchers has shown that a mutation within severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent responsible for the coronavirus disease 2019 (COVID-19) – enables the pathogen to evade antibody-mediated immunity while maintaining replication fitness and increasing viral loads. The researchers showed that a variant in the viral spike...

Children produce different antibodies in response to SARS-CoV-2
by Columbia University Irving Medical Center Children and adults produce different types and amounts of antibodies in response to infection with the new coronavirus, SARS-CoV-2, a new study from researchers at Columbia University Vagelos College of Physicians and Surgeons has found. The differences in antibodies suggest the course of the infection and immune response is distinct in children and most...
