SARS-CoV-2-induces temporary loss of smell in mice

Now, a new study published on the preprint server bioRxiv in November 2020 presents the onset of olfactory dysfunction (loss of smell) in mice infected with the virus, examining this process at the cellular level. In doing so, this study throws more light on this curious symptom and COVID-19’s manifestations outside the lungs.

Modeling suggests lower COVID-19 cases in Lombardy's second wave

Researchers found a negative association between the number of excess deaths during the first wave of the epidemic and the number of second-wave cases. This could be because of both a sort of herd immunity and changes in behavioral response.

Convalescent plasma in COVID-19 can be effective, especially early in disease

A team of researchers in the United States have conducted an extensive literature review looking at the usage of convalescent plasma from recovered COVID-19 patients to treat those with an impaired immune system. Their study, titled “Therapeutic use of convalescent plasma in COVID-19 patients with immunodeficiency: A systematic review,” has been released on medRxiv*, the preprint server.

Peptide-conjugated morpholino oligomers effectively inhibit SARS-CoV-2 in vero cells

The hunt for antivirals has reached an unprecedented pace in light of the coronavirus 2019 (COVID-19) pandemic. The causal agent for this disease – severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – has already infected over 52 million people worldwide, and has subsequently claimed over 1.3 million lives. However, among the innumerable promising drug candidates that help battle the virus and mitigate its damage, none have yet made it to the clinic.

Rhesus monkeys and cats potential spillover reservoirs for COVID-19 virus

A team of researchers from Switzerland, Costa Rica and Germany has conducted a study showing which animal species could potentially serve as spillback reservoirs of severe acute repertory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

"Cat's claw" extract inhibits replication of SARS-CoV-2 in vitro

Researchers in Columbia and Peru have shown that Uncaria tomentosa – a woody vine native to South America known of as "Cat's claw" – exerts in vitro antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent that causes coronavirus disease 2019 (COVID-19).

Antidepressant drug fluvoxamine may prevent some serious complications of COVID-19

In a preliminary study of COVID-19 patients with mild-to-moderate disease who were attempting to recover in their homes, researchers at Washington University School of Medicine in St. Louis have found that the drug fluvoxamine seems to prevent some of the most serious complications of the illness and make hospitalization and the need for supplemental oxygen less likely.

Pollution may bear part of the blame for rapid spread SARS-CoV-2 in the U.S.

The United States may have set itself up for the spread of a pandemic without even knowing it.

Common spike mutation may make SARS-CoV-2 more susceptible to a vaccine

A new study published in Science confirms that SARS-CoV-2 has mutated in a way that's enabled it to spread quickly around the world, but the spike mutation may also make the virus more susceptible to a vaccine.

Nursing homes still see dangerously long waits for COVID test results

Nursing homes are still taking days to get back COVID-19 test results as many shun the Trump administration's central strategy to limit the spread of the virus among old and sick Americans.

IMCRC launches new funding initiative with an Australian first rapid COVID-19 test

Innovative Manufacturing Cooperative Research Centre (IMCRC) has launched its new funding initiative, IMCRC activate, with an Australian first — the development of a rapid COVID-19 test that uses optical technology.

New process helps preserve viral vaccines without refrigeration

Ever receive a vaccination that seemed to burn a lot while it was injected? The vaccine solution likely contained a lot of salt or sugar - natural preservatives that help keep it stable, in addition to the cold temperature at which it was kept.

COVID-19 treatments for people with early infection should be prioritized

COVID-19 treatments for people with early infection are needed urgently, according to a JAMA Viewpoint article by National Institute of Allergy and Infectious Diseases (NIAID) Director Anthony S. Fauci, M.D., and colleagues.

Disinfectants with "virucidal activity against enveloped viruses" effective against SARS-CoV-2

A recent study demonstrated that two commercially available surface disinfectant formulations and one hand disinfection formulation that claim "virucidal activity against enveloped viruses" are effective in inactivating the SARS-CoV-2 virus. Their study has been published on the preprint server bioRxiv.

Researchers identify acrylamides that inhibit SARS-CoV-2 main protease

A new study in the preprint server bioRxiv published in November 2020 describes the discovery of acrylamide fragments that can effectively disable key enzymes in both the hand, foot and mouth virus and SARS-CoV-2 virus.

Human coronaviruses cause processing body loss

Researchers continue to expand their knowledge of coronaviruses, including the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pathogen. Now, a new study published on the preprint server bioRxiv in November 2020 describes a vital mechanism whereby the novel SARS-CoV-2 pathogen can restrict the human host response. In doing so, the study explores how this novel feature of SARS-CoV-2 works and how it results in a reshaping of the human host's immune response.

Research shows a unique T cell receptor repertoire in MIS-C patients

Children with coronavirus disease 2019 (COVID-19) sometimes develop the Multisystem Inflammatory Syndrome in Children (MIS-C), which is associated with high morbidity. The underlying T-cell associated mechanism is described by researchers in a new study published on the preprint server bioRxiv in November 2020, as a response to superantigen activation.
