NewsCats can play a role in family transmission of COVID-19
Cats can play a role in the transmission of SARS-CoV-2 and their contaminated environment can be infectious, according to new research.

OpinionThe threat of viral zoonosis hasn’t gone away
Why we’re liable to be ambushed by viral zoonosis - despite everything we’ve learned from Covid

NewsCovid beta variant in Mozambique transmitted through regional migration
A genomic surveillance study in Mozambique reveals that the beta variant of the virus was transmitted through regional migration, and questions the benefits of closing borders.

NewsLaser breathalyzer sniffs out COVID in real time
Scientists have made an important leap forward in the quest to diagnose disease using exhaled breath, reporting that a new laser-based breathalyzer powered by artificial intelligence (AI) can detect COVID-19 in real-time with excellent accuracy.
-
NewsConcerns raised over popular Covid disinfectants
The Covid-19 pandemic has boosted the unnecessary use of antimicrobial chemicals linked to health problems, antimicrobial resistance, and environmental harm, scientists warn.
-
NewsAlgorithm boosts Covid vaccine response 128-fold
Researchers have developed an AI algorithm that can rapidly design highly stable COVID-19 mRNA vaccine sequences that were previously unattainable, achieving a 128-fold increase in the vaccine’s antibody response.
-
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.
-
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.
-
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.

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.
