NewsInfluenza of avian origin confirmed in a sheep in Yorkshire
The UK’s Chief Veterinary Officer has confirmed a case of influenza of avian origin (H5N1) in a single sheep in Yorkshire following repeat positive milk testing.

NewsNature’s warriors: How rice plants detect and defend against viral invaders
A groundbreaking study uncovers a molecular mechanism by which rice cells perceive viral infections and initiate antiviral response, which significantly contributes to understanding of virus-host interactions for further disease resistance breeding.

NewsMcMaster leads Canada’s first-ever guidelines for Post COVID-19 Condition
A team of experts from McMaster University has led the creation of Canada’s first-ever comprehensive guidelines for diagnosing, managing, preventing, and treating post COVID-19 condition (PCC), more commonly known as long COVID.

NewsH5N1 influenza viral lineages beginning to evade human immunological defenses
A new computer modelling approach predicts the protein-antibody interactions of the potentially pandemic-causing H5N1 avian influenza virus lineage. It helps to understand the viral evolution to ensure high vaccine efficacy.

NewsStudy identifies viruses in red tide blooms for the first time
A new study identifies viruses associated with Karenia brevis, the single-celled organism that causes red tide. By testing water samples collected from red tide blooms, the researchers found several viruses in blooms — including one new viral species.

NewsStudy yields new data on Mpox vaccine effectiveness in people with HIV
A new study has found that a single dose of the Imvanex vaccine provides protection against Mpox with 84% effectiveness. For people with HIV, however, a single dose of the vaccine fails to offer sufficient protection. All at-risk groups, especially people with HIV, should receive the second dose of the vaccine as recommended.

NewsImmature platelet fraction offers clinical predictor for enhanced platelet recovery in patients with dengue fever
Immature platelet fraction (IPF) is recognized as a marker for thrombopoiesis, but a new study indicates that IPF% can be utilized as a predictor of platelet increase in patients with dengue infection.

NewsTunnel-building virus: How Zika transmits from mother to fetus
For the first time, researchers demonstrated the component involved in the tunneling nanotubes built by Zika virus to infect placental cells, an infection mechanism which is unique to the Zika virus alone.

NewsCurrent antivirals likely less effective against severe infection caused by bird flu virus in cows’ milk
Scientists found that in a preclinical model, two FDA–approved flu antivirals generally did not successfully treat severe H5N1 infections. Meanwhile, the route of infection, whether through the eye, the nose or the mouth, significantly impacts effectiveness.

NewsMetagenomic analysis of tick-borne viruses in Inner Mongolia
A new study maps the landscape of TBVs in Inner Mongolia, but also highlights the potential spillover risk of TBVs. These findings underscore the urgent need for One Health strategies for monitoring emerging TBVs at the tick-human-livestock interface in northern China.

NewsNIH-sponsored trial of Lassa vaccine opens
A National Institutes of Health (NIH)-sponsored clinical trial of a candidate vaccine to prevent Lassa fever has begun enrolling participants at the University of Maryland School of Medicine, Baltimore.

NewsEpstein-Barr virus worsens ulcerative colitis by triggering macrophage pyroptosis through glycolysis
The study shows that EBV infection activates pyroptosis in intestinal macrophages by upregulating glycolysis. This process leads to the release of pro-inflammatory cytokines, which further damage the intestinal barrier and worsen colitis symptoms.

NewsCOVID-19 pandemic worsened mother and infant birth outcomes
Mothers who became pregnant after the start of the pandemic, those who experienced moderate-to-severe infections during pregnancy, and those who had infections during the third trimester were more likely to have adverse outcomes.

NewsStudy finds new targets needed for vaccine to prevent herpesvirus transmission to babies
Despite the lack of research on vaccines against congenital cytomegalovirus (CMV), a research has recently discovered that the virus is able to cause cross-placental transmission even with the absence of multple essential proteins, providing insights for future vaccine development.

NewsOlder adults might be more resistant to bird flu infections than children
Previous exposures to seasonal flu strains could prime the immune system to produce antibodies against the current version of H5N1 avian influenza virus in older adults, whilst children would benefit more from H5N1 vaccinations.

NewsFirst coronavirus similar to MERS is found in bats in South America
A novel coronavirus, which shares high genetic similarities with MERS-CoV, was identified in bats in the state of Ceará, Brazil. Experiments to find out whether it can infect humans are set to take place in collaboration with Hong Kong University.

NewsCOVID-19 discovery opens door to new treatments for chronic lung problems
A discovery was made to understand how severe viral infections, like COVID-19 and flu could destroy the ability of immune cells to repair the tissue damage in lungs, causing long COVID and other chronic lung diseases.

NewsResearchers develop method to identify dormant cells that carry HIV
A new method is developed that utilizes a fluorescent genetic switch to tag and trace the lineages of the HIV-infected cells, including the dormant ones. This system might help to develop target therapies for the infected immune cells.
