NewsStudy shows drop in use of antiviral medications in young children with influenza
Despite national medical guidelines supporting the use of antiviral medications in young children diagnosed with influenza, a recent study reports an underuse of the treatment.
-
NewsGenome researchers unfurl protective mantle of influenza virus
The structure of the flu virus’s protective mantle and its interactions with its RNA have been described on an atomic scale by a research team for the first time.

NewsNew guidelines unveil advanced strategies for HIV treatment and prevention
The International Antiviral (formerly AIDS) Society-USA (IAS-USA) has published new international guidelines for the treatment and prevention of HIV, based on significant advances in antiretroviral therapies and new prevention strategies such as pre-exposure prophylaxis.

NewsFederal needle exchange programs are cost-effective to reduce health care costs, blood-borne infections
Needle exchange programs are evidence-based strategies that prevent transmission of blood-borne viruses, reduce injection-related infections, improve access to medical care, and facilitate entry into substance dependence programs for people who inject drugs, says a new study.

NewsDiverse phage populations coexist on single strains of gut bacteria
A new study shows that a single bacterial species, the host of a phage, can maintain a diverse community of competing phage species. Several phage species coexist stably on a population of a genetically uniform strain of E. coli.

NewsBreakthrough of the Year: A drug that prevents HIV infection, providing six months of protection per shot
As its 2024 Breakthrough of The Year, Science has named the development of lenacapavir – a promising new injectable drug that prevents HIV infection. The award also recognizes related work surrounding gaining a new understanding of the structure and function of HIV’s capsid protein.

NewsResearchers uncover how bat-origin pathogenic viruses manipulate human cell death and inflammation
A new study offers insights into cell death regulation by viruses like SARS-CoV-2, and how bats and humans respond differently to tricks that such viruses use to manipulate the host’s defense.
-
NewsInitiative to start HPV vaccination at age 9 improved completion rates
A quality improvement program designed to increase earlier uptake of the human papillomavirus (HPV) vaccine raised vaccination rates significantly, according to a study.
-
NewsA new class of antivirals could help prevent future pandemics
A new study introduces a proof-of-concept for a novel class of antivirals that would target a type of enzyme essential not just to SARS, but also many RNA viruses, including Ebola and dengue, as well as cytosolic-replicating DNA viruses, including Pox viruses.

NewsUpdated Hep B vaccine more effective for people with HIV
A newer vaccine against hepatitis B virus was clearly superior to an older vaccine type in inducing a protective antibody response among people living with HIV who didn’t respond to prior vaccination, according to an international study.

NewsEl Niño increases infestations of mosquito that transmits dengue in São Paulo state, Brazil
A study by a group of scientists shows that larval infestations of Aedes aegypti in open-air disused containers increased in response to the effects of the weather phenomenon.

NewsNew study reveals how COVID-19 variants hijack human cells
A research team has successfully mapped what they call the “hijackome”, detailing how SARS-CoV-2 variants exploit specific cellular pathways.
-
NewsNew review highlights variant-specific differences in long COVID
Alpha and Delta variants have been linked to a higher prevalence of cardiopulmonary symptoms, such as breathlessness and chest pain, while Omicron infections show fewer severe cardiopulmonary effects but relatively higher incidences of fatigue and brain fog.

NewsAround 1 in 5 of the world’s under 50s living with genital herpes (HSV)
Around 1 in 5 of the world’s under 50s—846 million people—are living with genital herpes infection, and more than 200 million 15-49 year olds probably had at least one symptomatic outbreak of the infection in 2020, suggest the latest global estimates.

NewsNew study into the ecological role of deep-sea viruses
Researchers have found that marine viruses show clear distribution patterns throughout the ocean and are influenced by the depth of the ocean rather than the specific location.
-
NewsFirst mouse strain that is susceptible to severe COVID-19 without genetic modification is IDed
Mice with a genetically pure background are susceptible to severe SARS-CoV-2 infection, providing an essential tool to develop vaccines and therapeutics for future coronavirus variants and potential pandemics
-
NewsResearchers find rotavirus vaccine is safe for use in NICU babies
Transmission of rotavirus vaccine strains in a neonatal intensive care unit (NICU) is rare and without clinical consequences, suggesting that giving the rotavirus vaccine to eligible infants during their hospitalization provides immune benefits that outweigh any risks.
-
NewsNew hope in the fight against Hepatitis C: Broadly effective innovative vaccine design
Epitope-focused immunogens in mouse models with a human antibody repertoire triggered a robust immune response in a new study. The produced antibodies were capable of successfully neutralizing multiple genetically diverse HCV strains.
-
NewsNew antibody breakthrough offers hope against evolving SARS-CoV-2 variants
Researchers have discovered a groundbreaking monoclonal antibody capable of neutralizing a wide range of SARS-CoV-2 variants, including the elusive Omicron subvariants.
