NewsFitness landscape explains Covid variant origins
Researchers have uncovered the mechanisms behind the emergence of new and dangerous coronavirus variants, such as Alpha, Delta, Omicron, and others.

NewsMonoclonal antibody programme targets mucormycosis
Vitalex Biosciences has been awarded an SBIR Phase 2 grant from the National Institute of Allergy and Infectious Diseases (NIAID) at the National Institutes of Health for VX-01, a monoclonal antibody (mAB) programme targeting the debilitating indication of the fungal disease, mucormycosis.

NewsBCG does not protect health workers against Covid
A world-leading international trial into the immune boosting benefits of the tuberculosis vaccine, BCG, has found it does not protect healthcare workers against COVID-19.

NewsSystem targets and degrades viral RNA to treat Covid infection
Researchers have developed a system that directly targets and degrades the viral RNA genome, reducing infection in mice. The method could be adapted to fight off many viruses, as well as treat various diseases.

NewsStudy of Covid contamination of shipping materials may yield guidance for goods transportation
Researchers investigating how environmental factors affect the persistence of two different, highly transmissible Omicron variants on shipping materials find that viability depends on the type of surface, the temperature and the original viral concentration.

NewsFirst human respiratory organoid culture system reveals secret of Omicron’s transmissibility
Researchers have established the first human respiratory organoid culture system and unveiled a novel mechanism for the high transmissibility of SARS-CoV-2 Omicron variant.

NewsInfectious SARS-CoV-2 isolated from hospital air samples
Scientists have succeeded in isolating infectious particles of the SARS-CoV-2 virus from air samples collected from hospital rooms of COVID-19 patients and kept frozen for more than a year, a new study shows.

NewsGut bacteria could be behind weaker immune responses to COVID-19 vaccine
Digestion of fucose sugar by bacteria in our digestive tract could be hampering how effectively we respond to the COVID-19 mRNA vaccine.

NewsProtein 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.

NewsMore 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.

NewsSpread 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.
-
NewsOmicron 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.
-
NewsMask 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.
-
NewsResearchers 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.
-
NewsSARS-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.
-
NewsBats 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.
-
NewsStudy 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.
-
NewsTeam 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.

NewsNasal 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.

NewsNext 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.
