Study explores how SARS-CoV-2 mutations produce antibody resistance and enhanced transmissibility

An interesting new study deals with the effects of the natural mutations in the spike antigen of the SARS-CoV-2, the pathogen that is responsible for the ongoing coronavirus disease pandemic.

Backtracking occurs within SARS-CoV-2 replication-transcription complex

Researchers continue to achieve a better understanding of SARS-CoV-2, the virus behind the ongoing COVID-19 pandemic. One such effort has been reported in a new preprint on the bioRxiv server, dealing with the phenomenon of backtracking.

The role of RNA capping of SARS-CoV-2 in immunity evasion

The SARS-CoV-2 pathogen successfully uses multiple immune evasion mechanisms to achieve infection within its host. An intriguing new study describes one such process, which may help develop drugs to counteract the virus more effectively.

New study tests how mutations in SARS-CoV-2 affect antibody neutralization

Using pseudoviruses with single amino acid substitutions, researchers found that mutations in SARS-CoV-2 reduce monoclonal antibody neutralization differently. However, convalescent sera samples did not lose neutralization potency many and were also effective against the B.1.1.7 (UK-derived) strain.

COVID-19 pandemic is affecting quality of care given to small and sick newborn babies

The COVID-19 pandemic is affecting the quality of care given to small and sick newborn babies in all regions of the world and threatening implementation of life-saving interventions, suggests new research published in BMJ Global Health.

Study suggests daily testing instead of self-isolation for contacts of SARS-CoV-2 cases

In the study, which appeared in the pre-print server medRxiv*, the researchers aimed to evaluate the acceptability and engagement with the daily testing as an alternative to self-isolation. They found that daily testing is acceptable and may help promote adherence to self-isolation.

An increase in the risk of clinical sequelae after SARS-CoV-2 infection

A new piece of research, published on the medRxiv preprint server, focused on the role of factors such as gender, age, hospitalization, etc., in understanding the risks of clinical sequelae in the post-acute phase of COVID-19, in adults aged between 18 and 65 years.

Study of post-acute sequelae of SARS-CoV-2 infection shows persistent symptoms 8 months

Researchers from the US recently studied the prevalence of PASC in a well-characterized cohort of patients to gain insights into the period following acute SARS-CoV-2 infection. The research is posted online to the preprint server medRxiv.

New SARS-CoV-2 lineage has spread across many Brazilian states

Researchers in Brazil have identified the emergence of a new lineage of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Brazil that has spread across multiple states in the country.

Chimeric vaccines may provide universal protection against viruses like SARS-CoV-2

Researchers in the United States have developed “chimeric” vaccines that provided cross-protection against different strains of sarbecovirus in mice, including the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19).

Study unveils SARS-CoV-2 persistence and contamination concentration on common surfaces

A recent environmental study from the United Kingdom, currently available on the bioRxiv preprint server, shows that certain common surfaces could represent an infectious risk if contaminated with high concentrations of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – albeit the level of viable viral particles is likely to be low.

Skin rashes more common in adults tested positive for COVID-19

Previous studies conducted in hospitals reported that COVID-19 patients presented with unusual skin rashes.

Researchers use wastewater to monitor prevalence of COVID-19 for first time in United Arab Emirates

Early warning systems are vital in preventing surging waves of the coronavirus disease 2019 (COVID-19) pandemic. Researchers have used wastewater samples to detect the spread of the virus in the United Arab Emirates from municipal and commercial aircraft, the first of its kind in the country, and the largest to date.

White-tailed deer susceptible to SARS-CoV-2, finds study

White-tailed deer have been observed to be susceptible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). They can also transmit the virus both through direct and indirect contact to one another, researchers find. The research paper is available to be read online in the Journal of Virology.

The role of nanotechnology in the fight against COVID-19

Appearing in the journal Nanomedicine, the review summarized all the exciting advances made using diverse nanomaterials (polymeric, inorganic self-assembling materials and peptide-based) towards COVID-19 prevention, diagnosis and therapy.

15 Mar 2021

SARS-CoV-2 UK variant could be more lethal than others

A new study has assessed the mortality risk of patients infected with the newly emerged UK variant (Lineage B.1.1.7) of SARS-CoV-2. The findings reveal that compared to the previously circulating SARS-CoV-2 variants, the UK variant significantly increases the risk of mortality in a relatively low-risk community population.

What is a protective neutralizing antibody titer against SARS-CoV-2 infection?

A new study describes a predictive model of protective immunity against SARS-CoV-2 infection that could help evolve optimal vaccination strategies to maintain protection and reduce the death rate.

15 Mar 2021

Why does convalescent plasma therapy for severe COVID-19 show mixed success?

A surprising new preprint, released on the medRxiv* server, suggests that the beneficial effects of convalescent plasma (CP) in this disease stem not only from the presence of neutralizing antibodies, but also the immunomodulatory effects of this plasma that shapes the host immune response.

15 Mar 2021

Which biomarkers can help predict severe COVID-19?

The ability to detect potentially fatal illness early on in the course of the disease would enable a swift prioritization of these high-risk individuals for treatment. A new preprint on the medRxiv* server presents an array of biomarkers that may help achieve this laudable goal.
