Alpha variant mutations help SARS-CoV-2 overcome evolutionary weaknesses

The study, published in the journal Cell Reports, showed that the mutations in the virus, particularly the deletion of two amino acids H69/V70 seen in the Alpha variant (B.1.1.7), enables the virus to overcome weaknesses as it evolves.

Frequent testing increases chance of detecting COVID-19 infections

The chance of detecting the virus that causes COVID-19 increases with more frequent testing, no matter the type of test, a new study found. Both polymerase chain reaction and antigen tests, paired with rapid results reporting, can achieve 98% sensitivity if deployed at least every three days.

Moderna's COVID vaccine effective against emerging variants including Delta

Researchers in the United States have analyzed the neutralizing activity of Moderna’s mRNA-1273 vaccine against several variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Study provides important insights into early stages of SARS-CoV-2 infection

Researchers in the UK have provided important new insights into the early stages of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Solar irradiation inactivates SARS-CoV-2 and other human coronaviruses, finds study

Coronaviruses irradiated with simulated sunlight used to infect cells showed reduced infectivity and reduced viral replication compared to viruses that were not irradiated.

Employed individuals more likely to be infected with the flu virus

A University of Arkansas researcher and international colleagues found that employed individuals, on average, are 35.3% more likely to be infected with the flu virus.

Is the SARS-CoV-2 delta variant threatening vaccine efficacy?

A new study in the UK, by researchers at Imperial College London, The Francis Crick Institute and the University of Glasgow, explores the loss of coronavirus disease 2019 (COVID-19) vaccine efficacy against the virus behind the current pandemic caused by the emergence of newer variants that have undergone mutational escape.

Effectively monitoring COVID-19 in reopened educational institutions: the San Diego model

An interesting new study from the University of California San Diego (UCSD) shows that using preventive measures to block viral transmission, coupled with repeated testing and rapid turnaround times for the results, can successfully prevent outbreaks associated with the reopening of educational institutions.

Is mild COVID-19 in children due to stronger antiviral innate immunity in the upper airway?

A new preprint on the medRxiv* server adds fuel to this train of thought, showing that the required cell program is already active in children – namely, a higher expression of specific pattern recognition receptors (PRRs), which mediate an interferon (IFN) response.

Assessing the safety of inactivated SARS-CoV-2 vaccine (CoronaVac) in healthy children and adolescents

New clinical trial data, recently published in The Lancet’s Infectious Diseases, presents an initial report on the effect of an inactivated SARS-CoV-2 vaccine, CoronaVac, on children and adolescents from ages 3-17 in a double-blind, randomized setting.

SARS-CoV-2 inhibited by pyrimidine biosynthesis inhibitors in conjunction with nucleoside analogs

In an effort to hasten the research on identifying antiviral drugs for SARS-CoV-2 infection, researchers from the U.S. and Switzerland performed extensive drug screening for antiviral activity using live virus infection in human respiratory cells. As a result, they identified a set of possible drug candidates that could potentially be tested in clinical trials.

COVID-19 prevalence among hospitalized infants may depend on levels of community transmission

How common COVID-19 is among infants may depend on the degree of the pandemic virus circulating in a community, a new study finds.

Researchers identify key protein that allows cancer-destroying viruses to enter tumor cells

Researchers from the Laboratory of Oncolytic-Virus-Immuno-Therapeutics (LOVIT) at the LIH Department of Oncology (DONC) are working on the development of novel anticancer strategies based on oncolytic viruses, "good" viruses that can specifically infect, replicate in and kill cancer cells.

Study shows SARS-CoV-2 breakthrough infections fewer among fully vaccinated

A team of researchers at Indiana University reports genomic evidence of breakthrough infections in fully vaccinated individuals. The study, posted to the pre-print server medRxiv*, suggests that fully vaccinated individuals, including those with asymptomatic infections, are less likely to serve as a source of infection for others.

Researchers explain how air turbulence create potentially virus-laden droplets

Computer simulations have been used with great success in recent months to visualize the spread of the COVID-19 virus in a variety of situations.

New biomarkers can predict HIV remission after antiretroviral therapy interruption

New biomarkers that predict HIV remission after antiretroviral therapy (ART) interruption are critical for the development of new therapeutic strategies that can achieve infection control without ART, a condition defined as functional cure.

Alpha (B.1.1.7) SARS-CoV-2 variant associated with more severe disease in hospitalized women

Researchers in the UK have conducted a study showing that infection with the B.1.1.7 (Alpha) lineage of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may be associated with an increased risk of death or intensive care unit (ITU) admission among women, compared with non-B.1.1.7 infection.

Widespread SARS-CoV-2 mutation escapes vaccine- and infection-induced CD8 T-cell responses

Researchers in the UK have warned that a widespread mutation that has arisen in the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) appears to escape recognition by CD8 T-cell responses in both convalescent patients and recipients of the current coronavirus disease 2019 (COVID-19) vaccines.
