NewsSepsis study IDs simple ways to save lives in Africa
Tuberculosis (TB) is a major unrecognized cause of deadly sepsis among people with HIV in Africa, a new study reveals. It found that more than half of the hundreds of patients enrolled in the study had TB and that immediate treatment increased their chances of survival significantly.

NewsMetformin shown to prevent Long COVID across risk groups in multiple randomized trials
Multiple randomized clinical trials and electronic health record studies now show that metformin, a widely used and well-established medication, significantly reduces the risk of developing Long COVID when taken during or shortly after acute infection with SARS-CoV-2.

NewsNipah virus outbreak: Risk of global threat is low, say experts
The Global Virus Network is monitoring reports of a Nipah virus outbreak in India and emphasizes that such cases, while very concerning and serious, are not unexpected or unprecedented.

NewsFrom biocidal coatings to medicines: A nanocomposite sting for microorganisms
A surface capable of responding to chemical signals generated by microorganisms and automatically producing biocidal substances – a description of how the B-STING silica nanocomposite works. The new material acts as a nanofactory of reactive oxygen species, activating only when necessary.

NewsAddressing rapid viral evolution: research team unveils emerging techniques for RNA viruses diagnostics
The rapid evolutionary dynamics of RNA viruses, driven by high mutation rates and the consequent formation of complex quasispecies populations, present a formidable obstacle to conventional molecular diagnostic approaches, warn researchers.

NewsNasal vaccine combats bird flu infection in rodents
Researchers have developed an intranasal H5N1 vaccine that elicited strong immune responses when tested in hamsters and mice and prevented infections in exposed animals. The team also confirmed their vaccine remained effective regardless of prior flu exposure.

NewsScientists say these two viruses may become the next public health threats
Two emerging pathogens with animal origins — influenza D virus and canine coronavirus — have so far been quietly flying under the radar, but researchers warn conditions are ripe for the viruses to spread more widely among humans.

NewsIn rare cases, autoantibodies can cause severe reactions to a live-attenuated virus Chikungunya vaccine that has been discontinued in the U.S.
A new study shows that preexisting autoantibodies in a small subset of the population can allow weakened vaccine viruses to escape control, explaining some adverse events tied to one kind of Chikungunya vaccine, which is no longer available in the U.S.

NewsResearchers demonstrate SARS-CoV-2 virus inactivation/destruction using focused sound waves
A team of researchers has successfully demonstrated the destruction of SARS-CoV-2 virus particles through exposure to high-frequency sound waves, marking a promising advance in non-pharmacological antiviral strategies.

NewsCOVID-19 viral fragments shown to target and kill specific immune cells
New research shows that after the body’s defenses kill the virus behind COVID-19, leftover digested chunks of SARS-CoV-2 spike protein can target specific immune cells based on their shape. It could explain why certain populations of cells that detect and fight infection are depleted in patients with severe COVID-19.

NewsAltered brain connection found in people with ME/CFS and Long COVID
People with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and Long COVID experience a disruption to their brain connectivity during a mentally demanding task. New research used ultra-high field MRI technology to investigate the significant reduction in brain connectivity in specific parts of the brain.

News‘Nudging’ both patients and providers boosts flu vaccine numbers
Patients were 28 per cent more likely to get a flu shot when they got a text message reminder and their primary care provider already had an order for the shot waiting, new research showed.

NewsLong COVID brain fog far more common in US than India, other nations
Patients with long COVID-19 in the U.S. report far higher rates of brain fog, depression and cognitive symptoms than patients in countries such as India and Nigeria, according to a large international study.

NewsScientists develop novel live-attenuated vaccine that blocks coronavirus transmission with a single intranasal dose
A research team at the LKS Faculty of Medicine, the University of Hong Kong (HKUMed), has developed a novel live-attenuated vaccine candidate, cb1, capable of generating broad immunity against a wide range of beta-coronaviruses with a single intranasal dose. Source: NIAID-RML This colorized transmission electron microscope image shows ...

NewsStudy suggests link between viral infection and ALS
Researchers have made a potentially game-changing discovery about the development of devastating motor neuron diseases. They identified a specific type of mouse — the CC023 strain — that responds to a viral infection in a way that looks remarkably similar to humans with amyotrophic lateral sclerosis.

NewsEndogenous retroviruses promote early human zygotic development
New findings offer insight into why some embryos fail to develop past zygotic genome activation (ZGA), pointing to an unexpected root of human infertility.

NewsMajor clinical trial provides definitive evidence of impacts of steroid treatment on severe brain infection
A major UK clinical trial has shown that adding the corticosteroid dexamethasone to standard antiviral treatment for encephalitis, caused by herpes simplex virus (HSV) does not improve long-term outcomes overall, although early use may lead to better recovery.

NewsScientists discover novel immune ‘traffic controller’ hijacked by virus
Researchers have discovered a tissue protein that acts as a central ‘traffic controller’ for immune cells and can be hijacked by a virus to weaken immune responses. Cytomegalovirus (CMV) can hijack this system by producing a protein that blocks CD44 function on stromal cells.

NewsMost would recommend RSV immunizations for older and pregnant people
A US survey found an increase in awareness of immunizations that are available for RSV. The survey of 1,637 U.S. adults also found that about 6 in 10 respondents would recommend the vaccine or antibody injections to the groups recommended by the CDC, an increase from past years.
