People may have a pre-existing immune response to COVID-19 thanks to common colds

Now, a new study shows that some people have immune responses against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19, thanks to how the body reacted the last time it caught a cold. This means that even if a person has not been exposed to the novel coronavirus, the body has a memory of it and can trigger an immune response to fight the infection.

Vaccine 'nationalism' will slow coronavirus fight if poor countries are left exposed

As the coronavirus vaccine race charges on, many of the investigational candidate vaccines are nearing the final stages of human trials. The results of these trials will determine if they will be granted the green light to manufacture and distribute the vaccine to countries across the globe.

COVID-19 patient with repeatedly undetectable SARS-CoV-2 antibodies

A recent case study published in the Journal of Applied Laboratory Medicine in August 2020 illustrates this with its finding of persistent seronegativity in a patient confirmed to be SARS-CoV-2 positive.

DHODH inhibitor PTC299 shows potential as a COVID-19 therapeutic

As COVID-19 continues to take a heavy toll on human health and life in many parts of the world, there is still no effective antiviral drug or vaccine. This has fueled an intensive search for small molecules and proteins that can inhibit viral entry and replication.

USA the source of most of New Zealand's coronavirus cases

New Zealand, an island country in the southwestern Pacific Ocean, is marked by its early and fierce determination to totally arrest the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the viral illness that is causing the current COVID-19 pandemic.

How have non-pharmaceutical interventions helped in COVID-19?

The COVID-19 pandemic shows no signs of abating, with outbreaks in many spots still occurring across the world. From the start, health organizations and governments were focused on implementing non-pharmaceutical interventions (NPIs) in the absence of any effective antivirals or vaccines.

Speed of Novavax vaccine development does not compromise quality of the SARS-CoV-2 immunogen

A new study by researchers from the Scripps Research Institute and Novavax Inc. in the US affirms the structural integrity of the full-length SARS-CoV-2 spike glycoprotein immunogen. It enables the interpretation of immune responses to this multivalent nanoparticle immunogen. Their results are currently available on bioRxiv preprint server.

Encouraging results from Phase I NovaVax SARS-CoV-2 nanoparticle vaccine trial

NVX-CoV2373, a recombinant nanoparticle vaccine developed by Novavax and manufactured at Emergent Biosolutions, was found to be well tolerated and immunogenic – inducing T-cell response and neutralization antibodies four-fold higher than the mean observed in hospitalized coronavirus disease (COVID-19) patients, shows a recent study available on the medRxiv* preprint server.

Cutting edge synthetic peptides block SARS-CoV-2 (COVID-19)

Researchers at Ligandal Inc., the University of California San Francisco and Toyota Technological Institute at Chicago, have designed novel synthetic peptides that potently inhibit the ability of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to infect host cells.

Community-based sampling needed for COVID-19 control, say researchers

Researchers in the UK have warned that it will be essential to carry out community-based sampling in addition to symptomatic testing if the ongoing transmission of severe acute respiratory syndrome coronavirus 2 (SARs-CoV-2) is going to be properly understood and controlled.

Humans promote diseases from the animal kingdom

The coronavirus pandemic, which has now infected nearly 19 million and killed more than 712,000 people, most likely originated from bats. Just like other coronavirus outbreaks in the past, a spill-over event or zoonosis caused the viruses to jump from animals to humans.

Study shows recombination among SARS-CoV-2 strains is already occurring, but remains rare

A recent study by U.S. researchers, currently available on the bioRxiv preprint server, indicates that the recombination events among the viral strains of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are already occurring – however, considering current levels of viral genetic diversity, they are neither widespread nor readily detectable.

Heat suggested as a therapeutic intervention in COVID-19

Viruses that are contained within a lipid membrane or “enveloped viruses” such as coronaviruses and rhinoviruses can remain active for long periods in cool, dry conditions, which can lead to increased rates of respiratory infections.

COVID-19 in pregnancy - premature birth common

A new study conducted by researchers at Yonsei University College of Medicine, Korea, suggests that while having coronavirus disease 2019 (COVID-19) during pregnancy has little effect on fetal or neonatal mortality, it can be associated with premature birth and sometimes severe outcomes for mother and baby, including death.

Human encroachment into forest land caused bat CoV spillover and COVID-19 emergence

A new study published on the preprint server medRxiv in August 2020 discusses the root causes underlying the emergence of such infectious diseases following their crossover of the line separating animal viruses from human. This initial event is of enormous significance.

Face masks protect from COVID-19 and other respiratory illnesses

Now a new study published on the preprint server medRxiv in August 2020, therefore, presents the results of a meta-analysis that takes account of the lack of compliance with mask-wearing in RCTs, as well as the lag between the event and the measurable effects.

Cats susceptible to and potential reservoirs for novel coronavirus

The study published on the preprint server bioRxiv in August 2020 shows that this is indeed taking place, with pet cats being infected and passing on the infection to contacts. It also offers the chance to see how the disease progresses in a susceptible host.

Recovered COVID-19 patients report hair loss months after infection

Several members of Survivor Corps, the Facebook support group of people who have had COVID-19, recently tackled about experiencing hair loss months after recovering from the wrath of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2).

Viable SARS-CoV-2 aerosols detected in a hospital room with COVID-19 patients

Now, a new study by researchers at the University of Florida highlights the role played by SARS-CoV-2 aerosols in disease transmission.

High altitude may act as a protective factor against COVID-19

The analysis by researchers from Spain and Peru reveals that high altitude confers significant protection from coronavirus disease (COVID-19) infection and death – independent of the distance from the pandemic epicenter, population density, or poverty levels. The study is currently available on the medRxiv preprint server.
