NewsCanada is slowest in reporting bird flu – but COVID shows we can do better
A global study was conducted to measure the reporting speed of pandemic-causing bird flu H5N1 in different countries, among which Canada surprisingly came in last, addressing the need for improvements in the current monitoring procedures.

NewsResearchers find live hantavirus is carried in various New Mexico small mammal species
A study was carried out to find out the reasons why human cases of the sin nombre hantavirus were concentrated in one particular region of New Mexico, even though the virus was found in 30 species of rodents and small mammals endemic to a different region.

NewsHepatitis B: new rapid diagnostic test to halt mother-to-child transmission
Scientists have assessed a new rapid diagnostic test to identify pregnant women at elevated risk of transmitting hepatitis B to their babies. This diagnostic tool could help eliminate hepatitis B by preventing mother-to-child transmission during childbirth.

NewsMeasles elimination versus eradication: The difference explained
As of March 13, the CDC has confirmed 301 cases of measles as well as the death of a child in Texas. Amira Roess, an epidemiologist and professor of global health, clarifies the benefits of vaccinating children and adolescents against measles.

NewsTadpoles try to flee dangerous virus in their pond by growing much faster than normal
A new study shows that larvae of wood frogs respond to the presence of a deadly ranavirus by growing and maturing precociously. In response to ranavirus, tadpoles change their growth, development, and resource allocation, which may help them tolerate the energetic demands of infection or escape risky environments to avoid infection.

NewsGrowing body of evidence links HPV with heart disease
In addition to causing several types of cancer, human papillomavirus (HPV) appears to bring a significantly increased risk of heart disease and coronary artery disease, according to a study.

NewsNewer hepatitis B vaccine shows promise as booster for health care workers
A new study compares the effectiveness of Heplisav-B, a new hepatitis vaccine, vs. standard hepatitis B vaccines as a booster in previously vaccinated individuals.

NewsEvaluating DNA impurities in recombinant adeno-associated virus
A new study indicates that DNA impurities derived from plasmid and host cell DNA are encapsulated into recombinant adeno-associated virus (rAAV) capsids as single-stranded DNA.

NewsNew study reveals a safer alternative for long-term hepatitis B treatment
Researchers have studied the effects of switching from long-term tenofovir disoproxil fumarate to the antiviral besifovir dipivoxil maleatein (BSV) in patients with chronic hepatitis B. Switching to BSV may improve patient kidney and bone health.

NewsStudy evaluates airborne transmission risk of mpox compared to COVID-19 and smallpox
Scientists have found that the inhaled infectious dose of mpox is at least 100 times lower than that of SARS-CoV-2 and smallpox, making efficient respiratory aerosol transmission highly unlikely in its current form - but future viral evolution could alter this dynamic.

News‘Low-sugar’ vaccine can provide broad immunity against coronavirus variants
A universal vaccine for coronaviruses removes sugar molecules from an area of a coronavirus spike protein that rarely mutates and creates effective and plentiful antibodies to inactivate the virus.

NewsUKHSA highlights pathogens of greatest risk to public health in bid to boost preparedness
The UK Health Security Agency (UKHSA) has today published its view on the pathogen families that could pose the greatest risk to public health, in a bid to focus and guide preparedness efforts against these threats.

NewsScientists ID natural products targeting SARS-CoV-2 - including caffeine
Researchers used computational methods to identify potential inhibitors of SARS-CoV-2 spike proteins, revealing promising natural compounds for guiding antiviral drug development, including caffeine.

NewsNew study sheds light on how bacteria ‘vaccinate’ themselves with genetic material from dormant viruses
Scientists have gained understanding on how bacteria defend themselves from phages, through gaining “memories” from predecessor dormant phages. The study will inform new phage therapies for bacterial infections that confer resistance to antibiotics.

NewsSimulation model shows potential affordability of preventative HIV therapy for infants
A type of cost-effective HIV neutralizing antibodies was evaluated to prevent the viral infection in infants during breastfeeding in high HIV prevalance countries. This treatment option is comparatively cheaper and has high clinical impacts in high HIV burden settings to achieve global elimination.

NewsMovie reveals DNA unzipping mechanism with implications for viral and cancer treatments
A detailed unwinding mechanism of the double-stranded DNA has been uncovered for the first time using cutting-edge technology, revealing how cells begin the crucial process of copying their genetic material.

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.
