New study suggests an earlier and faster spread of COVID-19 than initially thought

Researchers from Kent University in the UK have shown that the first coronavirus disease (COVID-19) patient likely dates back to October 2019. They also found that the spread to other continents of its causative pathogen – the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – occurred faster and sooner.

Long COVID has low prevalence in school-age children, UK study suggests

A new study, released as a preprint on the medRxiv* server, offers some insights into what may be expected in this field, how common it is, how it presents, and how it compares with chronic sequelae of other respiratory viruses.

Green tea catechins might be useful as pan-coronavirus inhibitors

Scientists from the Queen’s University, Canada, have recently uncovered the broad-spectrum antiviral activity of epigallocatechin gallate, a bioactive compound from green tea, against highly pathogenic coronaviruses found in humans and animals. The compound prevents viral infection by interfering with virus-host cell attachment. The study is currently available on the bioRxiv* preprint server.

Bivalent DNA SARS-CoV-2 vaccine induces strong humoral and cellular immunity in mice

A team of UK-based scientists has developed and validated a DNA vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that encodes both spike receptor-binding domain (RBD) and nucleocapsid of the virus as vaccine immunogens.

A study of circulating biomarkers in hospitalized patients infected with SARS-CoV-2 alpha variant

Now, a new study published on the medRxiv* preprint server proposes a rapid method to identify the mutations in B.1.1.7 (N501Y mutation and H69/V70 deletion) and the impact of this variant on various biomarkers in hospitalized patients. This is the first study that correlates the biomarker levels to SARS-CoV-2 variants.

SARS-CoV-2 detection with a simple, inexpensive, and sensitive molecular test

Researchers from the US recently described a rapid molecular test named WHotLAMP for the detection of SARS-CoV-2 in saliva. WHotLAMP is easy to use, very sensitive at 3.6 viral RNA copies per microliter of saliva, specific, and inexpensive. This study is published on the medRxiv*preprint serve.

Study finds no evidence for remdesivir's benefit in severe COVID-19 patients

A new analysis of current data indicates that remdesivir does not show efficacy in regulating the severity of the illness.

SARS-CoV-2 Delta variant likely to become dominant in the United States

Researchers have conducted a study showing that the B.1.1.7 lineage of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that emerged in the UK is now rapidly being displaced as the dominant strain in the United States by the variants of concern B.1.617.2 (Delta) and P.1 (Gamma) that emerged in India and Brazil, respectively.

Research suggests people living with HIV/AIDS may be less susceptible to SARS-CoV-2

Researchers in India have conducted a study showing that the seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – was lower among people living with HIV and AIDS than among the general population.

CD39+ monocyte count higher in pregnant than non-pregnant COVID-19 patients

A new study published on the bioRxiv* server describes the changes in the representation of a subset of activated monocytes in this group of patients.

Increased severity of COVID-19 in pregnancy

A new preprint on the medRxiv* server provides more evidence that COVID-19 likely causes a more serious phenotype to arise in pregnant women.

SARS-CoV N protein elicits production of IFN-β by provoking ubiquitination of RIG-I, finds study

A recent study published in Frontiers in Immunology focuses on the roles of the SADS-CoV N protein in IFN suppression during infection.

Assessing the extent of community spread caused by mink-derived SARS-CoV-2 variants

A recent study published in The Innovation evaluated the possibility of community transmission caused by a SARS-CoV-2 variant from an animal.

SARS-CoV-2 infection and transmission in the North American deer mouse

A recent study conducted in Canada reports that the North American deer mouse can be infected with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from humans.

Indian SARS-CoV-2 variant has unique infection and immune escape strategy say researchers

Researchers have conducted a study suggesting that the B.1.617 lineage of SARS-CoV-2 that emerged in India has evolved a unique strategy.

A study on hospitalized COVID-19 patients who received plasma therapy

A new study has been published which focuses on the evaluation of the outcomes of infected COVID-19 patients who were treated with CCP therapy.

Natural compound myricetin shows antiviral potential against SARS-CoV-2

New findings from a team of Chinese researchers suggest natural compounds — specifically the flavonoid myricetin — could also be a potential drug candidate for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

Higher levels of antibodies from COVID-19 mRNA vaccine compared to natural SARS-CoV-2 infection

Researchers found antibody levels in mRNA vaccinated individuals varied with age, gender, and previous coronavirus disease (COVID-19) infection.

Study shows equitable allocation strategies for SARS-CoV-2 vaccines have a comparative edge

In a recent paper, US researchers demonstrate that equitable distributions of vaccines against COVID-19 are a very optimal approach.

Longitudinal study finds SARS-CoV-2 neutralizing antibodies decline a year after infection

Research led by Xin Zheng of Huazhong University of Science and Technology in Wuhan, China, found that about 90% of patients who recovered from COVID-19 continued to have IgG antibodies targeting the N-domain and receptor-binding domain of the spike protein. However, approximately 43% of patients showed signs of neutralizing antibody activity.
