NewsVirus infects cells with a protective cloaking mechanism
The discovery of a jumbo phage’s stealth compartment could be leveraged to engineer new therapies to treat antibacterial-resistant infections.
-
NewsNovel point-of-care technology delivers accurate HIV results in minutes
Scientists have developed new technology that could lead to the creation of a rapid point-of-care test for HIV infection competitive with traditional lab-based HIV testing in a fraction of the time and without the need for a stressful wait.
-
NewsMolecular stool test could improve detection of tuberculosis in adults with HIV
A prospective multicentre study highlights the potential of the Xpert MTB/Ultra stool test for diagnosing tuberculosis in people living with HIV.

NewsHantavirus in Madagascar linked to black rats in agricultural areas
A new study reveals that the black rat is likely responsible for transmitting deadly hantaviruses in rural Madagascar, where forested landscapes have been converted to agriculture and settlements.

NewsNew COVID-19 drug shows greater promise against resistant viral strains
A new standalone oral drug candidate has proven to be effective against Paxlovid-resistant COVID-19 strain in animal models. It works with low doses and cause no drug interaction-induced side effects.

NewsAn antiviral chewing gum to reduce influenza and herpes simplex virus transmission
Researchers have used a clinical-grade antiviral chewing gum to substantially reduce viral loads of two herpes simplex viruses and two influenza A strains in experimental models. The chewing gum could also work against bird flu.
-
NewsDiscovery of bacteria’s defence against viruses becomes piece of the puzzle against resistance
A new study shows that the emergence of resistance can be understood in the mechanism of how bacteria build up defences against being infected by viruses.
-
NewsA leap in viral research: More sensitive viral RNA detection
Researchers have unveiled an innovative, label-free ratiometric fluorosensor designed for the selective and sensitive detection of enteroviral RNA. The research promises to deliver even more advanced and effective detection methods.
-
NewsHow a small number of mutations can fuel outbreaks of western equine encephalitis virus
New research shows how small shifts in the molecular makeup of a virus can profoundly alter its fate. These shifts could turn a deadly pathogen into a harmless bug or supercharge a relatively benign virus, influencing its ability to infect humans.

NewsThe beginning of the end: Setting a global target for rubella eradication
Scientists discuss the 2024 World Health Organization’s (WHO) recommendation for universal introduction of rubella-containing vaccines (RCVs) into childhood vaccination programs in all countries – particularly in the remaining 19 countries that have yet to do so.
-
NewsNew carrier birds brought avian flu to Europe, Americas
Unexpected wild species, from pelicans to peregrine falcons, are transporting the virus from poultry farms to new places around the world and changing where the risk of outbreaks is highest.
-
NewsPinning down the process of West Nile virus transmission
A US project aims to use mathematical models to analyze how factors like temperature, light pollution, and bird and mosquito abundance affect West Nile virus transmission. The ultimate goal is to advise health departments of the best time of year to kill the bugs.
-
NewsHidden virus harboured by fruit flies may influence experimental accuracy
A new study suggests the presence of Nora virus in laboratory strains of Drosophila fruit flies influences their resilience to stress and bacterial infection and can confound experimental studies of ageing.
-
NewsFAU secures $1.3 million NIH grant for breakthrough in HIV self-test technology
To address the urgent need for a reliable, rapid and affordable self-test for early HIV detection, researchers have been awarded phase-II of a five-year, $1.3 million grant which will support the development of an innovative disposable microchip technology designed for HIV-1 self-testing during the first two weeks post-infection.

NewsMpox could become a serious global threat, scientists warn
Mpox has the potential to become a significant global health threat if taken too lightly. Scientists highlight how mpox – traditionally spread from animals to humans – is now showing clear signs of sustained human-to-human transmission.
-
NewsMOPEVACLAS vaccine candidate for Lassa fever enters clinical trials
After more than 20 years of research on arenaviruses, researchers have developed an original vaccine platform known as MOPEVAC. A Phase Ia clinical trial is set to begin for the platform’s first vaccine candidate, which targets Lassa fever, a hemorrhagic fever responsible for thousands of deaths worldwide each year.

NewsResearchers develop machine learning model to predict virus reservoirs
A new artificial intelligence tool could aid in limiting or even prevent pandemics by identifying animal species that may harbor and spread viruses capable of infecting humans.
-
NewsAI learns to ‘speak’ genetic ‘dialect’ for future SARS-CoV-2 mutation prediction
Researchers have developed a new method to predict mutations in virus protein sequences called Deep Novel Mutation Search (DNMS), a type of artificial intelligence model that uses deep neural networks.

NewsCompelling data point to a single, unknown respiratory virus as cause of Kawasaki disease
New research strongly suggests that Kawasaki disease is caused by a single respiratory virus that is yet to be identified. Findings contradict the theory that many different pathogens or toxins could cause this disease that can lead to serious cardiac complications in young children.

NewsOnly few disinfectants are capable of inactivating hepatitis A virus
Researchers tested nine different surface disinfectants against Hepatitis A virus. According to their findings, only two aldehyde-based products proved effective at inactivating HAV.
