Why SARS-CoV-2 B.1.1.7 is more virulent

A new preprint research paper by scientists from Sweden and India attempts to provide a preliminary answer to these questions using computational modeling. The research, which appears on the bioRxiv* server, predicts increased virulence with the new variant. If validated, this could help public health authorities prepare for new variants' possible impact as they emerge.

Vitamins and other antiviral drugs may help combat COVID-19

Evidence is emerging that vitamin D - and possibly vitamins K and A - might help combat COVID-19. A new study from the University of Bristol published in the journal of the German Chemical Society Angewandte Chemie has shown how they - and other antiviral drugs - might work.

Study shows why children of obese mothers have propensity to develop metabolic diseases

A Brazilian study published in the journal Molecular Human Reproduction helps understand why obese mothers tend to have children with a propensity to develop metabolic disease during their lifetime, as suggested by previous research.

Rapid reopening crucial in promoting the second wave of COVID-19

The spread of the coronavirus disease 2019 (COVID-19) has affected almost a hundred million people, with over two million deaths being attributed to this illness over the past 12 months or so. The only means to counter this so far has been through non-pharmaceutical interventions (NPIs).

Herd immunity to SARS-CoV-2 may not be achievable with current vaccines

A recent preprint research paper posted on the medRxiv server asks the question: “Is “herd immunity” to COVID-19 a realistic outcome of any immunization program with the two main vaccines currently licensed in the UK?”

Can the onset and end of an epidemic be predicted? A SARS-CoV-2 modeling case study

A recent study by researchers in France shows how differences in infection history and viral spread patterns are important factors in predicting the time course of a localized epidemic of SARS-CoV-2.

Busting myths on airborne transmission of SARS-CoV-2

The rapid spread of COVID-19 caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has led to significant research on the mechanisms of how the virus spreads, which is usually by airborne transmission.

Near-universal adoption of masks along with public health measures could eliminate disease spread

Research published this month in the Proceedings of the National Academy of Sciences found that near-universal adoption of nonmedical masks in public, combined with complementary public health measures, could reduce spread to essentially zero.

What are the key factors and impact of interventions in England’s COVID-19 epidemic?

Researchers from Imperial College London provide a mathematical model to help understand how SARS-CoV-2, the causative pathogen of (COVID-19), spread across England in the first two waves of the epidemic, and the effect of various interventions by the government.

More stringent measures may be needed to control new SARS-CoV-2 B.1.1.7 variant in England

Researchers in the UK have conducted a comprehensive epidemiologic analysis of the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant in an effort to learn more about the expanded range and frequency of coronavirus disease 2019 (COVID-19) cases in England.

Researchers claim SARS-CoV-2 B.1.1.7 variant likely to become globally dominant

The new variant of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) detected in England replicates more than two times faster than the earlier strains. This replication advantage promises to make it the dominant global variant very shortly. This finding comes from a startling preprint that appeared on the medRxiv* server in December 2020.
