Protein domain common to plants and animals plays role in COVID-19 infection
Scientists exploring bioenergy plant genetics have made a surprising discovery - a protein domain that could lead to new COVID-19 treatments.

More than 1 million lives saved across Europe by COVID-19 vaccines since the end of 2020
COVID-19 vaccination directly saved at least 1,004,927 lives across Europe between December 2020 and March 2023, according to new research being presented at ECCMID in Copenhagen, Denmark.

Spread of COVID-19 in households linked to virus on hands and surfaces, say researchers
A new Imperial College London-led study provides the first empirical evidence for transmission of SARS-CoV-2 via people’s hands and frequently touched household surfaces.

Omicron appears more deadly than seasonal influenza, study suggests
Adults hospitalised with the SARS-CoV-2 Omicron variant have a higher death rate than those hospitalised with seasonal influenza, even though Omicron is considered less virulent with lower case fatality rates than the delta and alpha strains, new research being presented at ECCMID suggests.

Mask rule in hospitals may have little impact on COVID-19 transmission during Omicron wave
A study in large London hospital during first 10 months of Omicron activity suggests the real-world benefit of mask-wearing in isolation is likely to be modest, according to new research being presented at this year’s ECCMID.

Researchers reveal why viruses like SARS-CoV-2 can reinfect hosts and evade immune response
Using a tool called VirScan, Brigham investigators found that people produced shared antibody responses to certain regions of the virus, likely leading to selective pressure and new variants that can repeatedly escape detection by prior immunity.

SARS-CoV-2 infection speeds up the progression of dementia, new study shows
All subtypes of dementia, irrespective of patients’ previous dementia types, behaved like rapidly progressive dementia following COVID-19.

Bats disturbed by humans are more frequently infected with coronaviruses
Bats in human-dominated ecosystems have a higher prevalence of coronaviruses, increasing the possibility that these could be transmitted to humans.

Study finds evidence of resistance to COVID-19 drugs
Resistance to Paxlovid is already evident among viral SARS-CoV-2 variants currently circulating globally, indicating that this stand-alone drug known as a protease inhibitor could soon become less effective in treating COVID-19 infections, a new study suggests.

Team designs molecule to disrupt SARS-CoV-2 infection mechanism
A team of scientists led by the Department of Energy’s Oak Ridge National Laboratory has designed a molecule that disrupts the infection mechanism of the SARS-CoV-2 coronavirus and could be used to develop new treatments for COVID-19 and other viral diseases.

Antibiotics do not reduce risk of dying in adults hospitalised with common respiratory infections, suggests study
Most patients admitted to hospital with acute viral respiratory infections are given antibiotics. Now new research to be presented at this year’s ECCMID in Copenhagen suggests that prescribing antibiotic therapy to adults hospitalised with common viral respiratory infections such as influenza is unlikely to save lives.

Nasal spray protects against coronavirus infection- including recent immune-evasive variants
Researchers have developed a molecule that is, when administered nasally, extremely effective in preventing the disease caused by all known variants of the SARS-CoV-2 virus.

Next epidemic could be spotted early in wastewater, say scientists
Researchers analysing wastewater say that routine monitoring at sewage treatment works could provide a powerful early warning system for the next flu or norovirus epidemic, alerting hospitals to prepare and providing public health agencies with vital health information.

Co-infection with ‘superbug’ bacteria increases SARS-CoV-2 replication up to 15 times
New research has revealed that IsdA, a protein found in all strains of Staph A., boosts SARS-CoV-2 replication by 10- to 15-fold.

Researchers discover previously unknown Achilles heel of Covid virus
Scientists concluded that only a survey of neutralising antibodies can inform us about protection against new Covid infections, then disovered a previously unknown weak point of the virus when analysing specific characteristics of those antibodies.

A water-dampened wipe removes Covid virus from indoor surfaces
Wiping indoor surfaces with a water-dampened wipe removes greater than 80% of Covid virus, yet pre-wetting the surface with water or detergent doesn’t make much difference, a new EPA study finds.

Inexpensive way to produce anti-Covid nanobodies cuts down on the llamas
Researchers have come up with a less expensive way to isolate and identify nanobodies that target various parts of the SARS-CoV-2 spike protein and are currently derived from llamas.

Common cold gives children immunity against COVID-19
Researchers have identified memory T cells in children’s blood samples taken before the pandemic that react to cells infected with SARS-CoV-2, the virus that causes COVID-19.

Naturally occurring amino acid could point way towards Covid cure
A promising treatment strategy that could pave the way for a Covid-19 cure is targeting angiotensin-converting enzyme 2 (ACE2), a receptor found on the cell membrane that allows entry of the virus into the cell due to its high affinity for SARS-CoV-2’s spike protein.
