Researchers offer large-scale screening of potential broad-spectrum SARS-CoV-2 antivirals

A new study describes the identification of new compounds from a library, with inhibitory activity against several coronaviruses. This study shows the utility of this method, besides identifying compounds that not only inhibit viral shedding in SARS-CoV-2 cultures, but have an immunomodulatory effect that may be useful in mitigating the damaging cytokine storm typical of severe or critical COVID-19.

Backed by millions in public and private cash, rapid Covid tests are coming to stores near you

Scientists and lawmakers agree that over-the-counter Covid tests could allow desk workers to settle back into their cubicles and make it easier to reopen schools and travel.

Could a flavonoid found in common fruit and vegetables combat COVID-19?

Researchers in India have gathered and presented a large body of evidence highlight quercetin – a flavonoid molecule found in many common fruits and vegetables – may be developed into drug therapies used to combat COVID-19.

New portable viral screening test can diagnose COVID-19 in minutes and track variants

Clinicians using a new viral screening test can not only diagnose COVID-19 in a matter of minutes with a portable, pocket-sized machine, but can also simultaneously test for other viruses--like influenza--that might be mistaken for the coronavirus.

mRNA COVID-19 vaccines are highly effective among front liners, CDC study shows

The study, published in CDC's Morbidity and Mortality Weekly Report (MMWR), highlights the efficacy of mRNA vaccines in protecting against SARS-CoV-2 infection.

Researchers develop novel test that screens for SARS-CoV-2 variants of concern

A team of scientists from the United States has recently developed a single-tube duplex molecular assay for rapid detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants containing E484K and N501Y spike mutations.

Single dose of Pfizer and Oxford vaccines shows 60% efficacy in elderly care home residents

A new study deals with the effect of two widely used vaccines in eliciting humoral immunity against the virus in this group. These are the Oxford/AstraZeneca viral-vectored vaccine (ChAdOx1 nCoV-19), and the Pfizer/BioNTech’s messenger RNA-based vaccine (BNT162b2). Both express the viral spike antigen, and both are currently being employed in the UK’s vaccination program.

New diagnostic test can detect COVID-19 virus even when it mutates

A team of scientists led by Nanyang Technological University, Singapore (NTU Singapore) has developed a diagnostic test that can detect the virus that causes COVID-19 even after it has gone through mutations.

30 Mar 2021

Researchers develop new rapid and highly sensitive SAR-CoV-2 RNA detection test

In an alternative approach to the PCR-based methods, CRISPR-Cas proteins have been employed by a large team of researchers to identify the SARS-CoV-2 genomic RNA in patient samples with PCR-derived cycle threshold (Ct) values up to 22 - corresponding to ~1600 copies/µl in the assay.

Large U.S. study identifies sociodemographic and clinical factors associated with SARS-CoV-2 testing and positivity

The massive and continuing outbreak of coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), throughout the world, has led to a staggering toll of over 549,000 deaths in the USA, among over 30 million cases. A new preprint research paper posted to the medRxiv* server discusses the factors related to the chances of testing positive for this virus.

Persistent impact on smell and taste in COVID-19 patients one year later

The presentation of the infection ranges from asymptomatic, through dry cough with fever, anosmia/dysgeusia, to shortness of breath with severe acute respiratory distress syndrome (ARDS). A new preprint research paper posted to the medRxiv* server reports on the clinical progression of anosmia and dysgeusia, in particular, one year after the infection.

Single Sputnik V vaccine dose elicits robust immune response in previously infected individuals

A new preprint research paper posted to the medRxiv server describes successful immunization of the vaccinated population with a single dose of the Russian-made Sputnik V vaccine.

Research finds polymerase of SARS-CoV-2 can adopt an alternative structure

New research by German scientists has uncovered another form of coronavirus polymerase. The current polymerase thought to be used for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a viral RNA-dependent RNA polymerase (RdRp) for replication and transcription. It contains a monomeric enzyme with the catalytic subunit nsp12, two copies of subunit nsp8, and one copy of subunit nsp7.

Could dry swabs provide cheaper, safer and faster material for SARS-CoV-2 testing?

A new study deals with the feasibility of using dry swab samples to isolate the virus, as compared to wet swabs, to reduce costs while improving safety.

25 Mar 2021

Three commonly used antiviral drugs potentially effective at preventing replication of SARS-CoV-2

An international team of researchers has found that three commonly used antiviral and antimalarial drugs are effective in vitro at preventing replication of SARS-CoV-2, the virus that causes COVID-19.

24 Mar 2021

Researchers develop innovative biosensor that can detect and quantitate SARS-CoV-2 infection

Researchers have generated protease-activatable fluorescent and luminescent biosensors for SARS-CoV-2 MPro (main protease) and PLPro (papain-like protease) activity, one based on “flip” GFP (FlipGFP), and the other based on circularly permuted firefly luciferase (FFluc).
