NewsSweeping up dust to detect emerging viruses
Gathering dust from buildings may hold promise as a more efficient way to track viral outbreaks in indoor settings, according to a new study. After collecting nearly 30 vacuumed dust samples from different buildings, researchers simultaneously identified the presence of 54 distinct viruses.

NewsMeasuring SARS-CoV-2 diversity in wastewater improves disease surveillance
Tracking the genetic diversity of SARS-CoV-2 in wastewater, rather than just viral abundance, dramatically improves the ability to monitor and predict COVID-19 outbreaks, researchers report.

NewsIgG fucosylation linked to severe COVID-19 progression and traditional Chinese medicine therapy
A new study has uncovered that immunoglobulin G (IgG) fucosylation, a critical type of protein glycosylation, is closely associated with the progression of severe COVID-19, offering new insights into disease pathogenesis and potential therapeutic strategies.

NewsDiseases can spread between apartments via shared ventilation, study shows
Airborne diseases like measles, influenza and COVID-19 can easily spread between units in multi-family buildings via a type of bathroom ventilation system commonly used around the world, new research suggests.

NewsFlawed but correctable research hindered progress in infection-triggered chronic conditions
Researchers contend that studies of infection-associated chronic illnesses such as Lyme disease and COVID-19 suffer recurring problems such as the failure to prove participants have the relevant pathogen.

NewsStudy reveals common mutation linked to autoimmune diseases may protect people from viral infections
New research shows a “risk gene” linked to higher odds of developing autoimmune diseases such as diabetes or lupus may also provide a survival advantage fighting viral infections like coronavirus. The gene PTPN22 carries a mutation, 1858C>T (R620W), found in roughly one in 10 people in North America.

NewsPregnant women’s mental images are directly linked to vaccine hesitancy and uptake
When pregnant women think about vaccinations, many experience vivid mental images – such as a sick baby in hospital – that have a direct link to their opinion of the vaccine and whether they ultimately have it, new research has shown.

News‘Atomic snapshots’ of proofreading enzyme could lead to better COVID-19 drugs
A research team used images generated by a cryogenic electron microscope (cryo-EM) to observe the interplay between SARS-CoV-2 proofreading enzyme exoribonuclease (ExoN) and RNA incorporated with antivirals such as remdesivir, sofosbuvir and bemnifosbuvir.

NewsSeasonal COVID-19 vaccination in 2025/26 reduced risk of illness by half in Canada
An interim analysis estimates that the COVID-19 vaccine for the 2025/26 season reduced the risk of illness in Canada by about half at about 9 weeks after vaccination, offering protection beyond the vaccine’s target strain.

NewsScientists use ultrasound to destroy influenza A and COVID-19 viruses without damaging human cells
Researchers have discovered that high-frequency ultrasound waves similar to those used in medical exams can eliminate viruses such as SARS-CoV-2 and H1N1 without damaging human cells. Acoustic resonance causes structural changes in viral particles until they rupture and become inactivated.

NewsResearchers flip the CRISPR script to develop world’s first DNA-guided gene editing tool for precise infectious disease diagnosis
A research team has successfully developed the world’s first DNA-guided CRISPR-Cas system capable of programmable RNA targeting and cleavage. This breakthrough overturns the conventional CRISPR paradigm, which uses RNA as a guide to target DNA.

NewsWhy feeling sick may be important for surviving infection
In a new perspective, scientists propose a different way of thinking about sickness symptoms: what if these behaviors are part of an integrated immune strategy that operates across scales — from individual cells to tissues and organs, to the whole organism — and helps promote survival?

NewsStudy confirms effectiveness of medicinal plant against SARS-CoV-2 virus
A study has revealed that galloylquinic acids extracted from the leaves of Copaifera lucens Dwyer, a tree endemic to Brazil primarily found in the Atlantic Forest, have a multi-targeted effect against SARS-CoV-2, the virus that causes COVID-19.
-
NewsNew study shows antibodies need a strong core — not just grip — to fight SARS-CoV-2
Researchers used advanced computer simulations to investigate how antibody–virus complexes respond to mechanical forces across multiple SARS-CoV-2 variants, including the original 2019 strain and Omicron subvariants BA.4 and JN.1.

NewsThe handbook that can prepare countries for the next pandemic
A new handbook has been published to pave the way for better decision-making and greater preparedness for the next pandemic. It provides practical guidance on how mathematical models can be used to inform decision-making, and how the results can be communicated in times of crisis.

NewsCOVID-19 and severe heart attack increase mortality by 25% after one year, more than double pre-pandemic rates
Findings from the North American COVID-19 Myocardial Infarction (NACMI) registry demonstrate significantly higher one-year mortality rates in patients with COVID-19 and ST-elevation myocardial infarction (STEMI) compared to patients with STEMI alone.

NewsSARS-CoV-2 does not persist in the placenta after maternal recovery from COVID-19
A new study finds that the virus that causes COVID-19 does not linger in placental tissue weeks to months after a pregnant woman recovers from infection - offering important reassurance for clinicians and patients alike.

NewsCOVID antiviral speeds recovery but doesn’t reduce hospitalization in vaccinated patients, trials find
Paxlovid (nirmatrelvir-ritonavir) does not reduce hospital admissions or deaths in vaccinated adults at higher risk of severe COVID-19, despite helping them recover faster, according to results from two national trials.

NewsStudying two very different viruses helps to develop new strategies
When the SARS-CoV-2 pandemic began, virologist Theodora Hatziioannou, in conjunction with Paul Bieniasz brought her HIV-honed skills and tools to this new global threat, which made it easier and faster for researchers to gain insights into the virus and test antibodies for potential therapeutic candidates in real time.
