Low-cost point of emission air purifiers can reduce airborne transmission of pathogens, says study

In a study conducted at the Monash University, Australia, scientists have examined the efficacy of portable air purifiers combined with a hood in reducing virus aerosol transmission and protecting healthcare workers from workplace contamination. The study is currently available on the medRxiv* preprint server.

Millions of Africans are at risk of contracting COVID-19 due to lack of public health tools

Millions of people across the African continent are at risk of contracting COVID-19 because of a lack of the most basic public health tools to protect themselves - including the essentials of soap and water.

Researchers discover glycan 'gates' that open to allow SARS-CoV-2 entry

Since the early days of the COVID pandemic, scientists have aggressively pursued the secrets of the mechanisms that allow severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to enter and infect healthy human cells.

Small study suggests a mix-and-match COVID-19 booster produces robust antibody levels

In a small study published in the medRxiv* preprint server, people given a booster Johnson & Johnson COVID-19 shot showed elevated and robust antibody levels.

SARS-CoV-2 antibodies found to neutralize bat coronavirus (RaTG13) in new study

A striking new study examines how far antibodies elicited by vaccines against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), or by natural infection, can neutralize the closely related bat coronavirus (CoV) RaTG13.

How does the SARS-CoV-2 Delta variant’s spike drive membrane fusion and immunity evasion?

A fascinating and timely new study shows how the Delta variant of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) achieved higher transmissibility and resistance to neutralization.

Durable highly protective T cell response to AAV-spike vaccine against COVID-19 pneumonia in mice

New research, available as a preprint on the bioRxiv* server, has focused on the role played by T cell immunity, particularly CD8+ cytotoxic T cells, on preventing lethal infection with SARS-CoV-2 in mice infused with peptide-loaded antigen-presenting dendritic cells (DCs).

Did particulate matter from wildfires cause excess COVID-19 deaths in the US?

New research published in Science Advances investigates the relationship between wildfire smoke and COVID-19 mortality using pollution and COVID-19 incidence and mortality data.

19 Aug 2021

Early clinical trial data in for whole virus COVID-19 vaccine candidate

In a study uploaded to the preprint server medRxiv*, the efficacy of a whole virion Coronavirus vaccine was determined by giving the vaccine to healthy adult volunteers, which generated a robust immune response with evidence of T-cell activation.

Scientists identify a potent neutralizing nanobody against SARS-CoV-1

In a recently published article in the journal Virologica Sinica, scientists have described the development and validation of a potent nanobody that targets the receptor-binding domain (RBD) of severe acute respiratory syndrome coronavirus (SARS-CoV). The nanobody efficiently and specifically blocks the interaction between RBD and angiotensin-converting enzyme 2 (ACE2) and neutralizes the virus.

White-tailed deer are highly susceptible to SARS-CoV-2 infection

The SARS-CoV-2 virus has been shown to infect a wide range of animals naturally and experimentally, and prior studies indicate deer are susceptible to infection. White-tailed deer (Odocoileus virginianus) fawns have been found to be susceptible to SARS-CoV-2.

19 Aug 2021

SARS-CoV-2 vaccine efficacy is strongly correlated with antibody neutralization levels

All COVID-19 vaccines appear less effective when faced with variants such as Delta, according to a new medRxiv* study. However, the researchers suggest that booster shots may help improve immunity and protect against symptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

CDC declares four new COVID high-risk travel destinations

The coronavirus disease (COVID-19) pandemic, caused by severe acute respiratory syndrome (SARS-CoV-2), is far from over. As the cases continue to rise, countries grapple with controlling the viral spread. To date, over 209 million individuals have been infected with SARS-CoV-2, with more than 17 million cases recorded worldwide over the past 28 days.

Severe COVID-19 characterized by phosphorylation of STAT1

A new study reports an enhanced expression of STAT1 in mild and severely infected COVID-19 patients as compared to controls

Why have COVID-19 caseloads been comparatively low in Africa?

A new study has been published in the International Journal of Environmental Research and Public Health that highlights the potential lessons that the world can draw from Africa on assumptions concerning viral pandemics. This is particularly important, given Africa’s long experience with dangerous infectious diseases.
