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.

NewsmRNA-based COVID-19 vaccines train the ‘long-term memory’ of the innate immune system
A study showed that vaccination of multiple mRNA-based COVID-19 vaccines could induce persistent epigenetic changes in innate immune cells, leading to long-term immune responses for SARS-CoV-2 and other pathogens.

NewsResearchers design genetic tools to develop vaccines more efficiently for African swine fever virus (ASFV)
A synthetic genomic-based reverse genetics tool has been developed for African swine fever virus (ASFV) that helps vaccine development to reduce the economic losses. The system may also be adapted to other emerging viral threats.

NewsScientists zoom in on structure of still lethal Ebola virus
The first high-resolution visualisation of the Ebola virus nucleocapsid provides detailed insights into the interactions within the nucleocapsid complex, unveiling the relationship between molecular interactions and functional regulation.

NewsProposed cuts to foreign aid could result in millions of HIV deaths, new modelling study estimates
New modelling analysis suggests that proposed funding cuts by major donor countries to foreign aid could undo decades of progress made to end HIV/AIDS as a public health threat and new infections and deaths could surge back to levels not seen since the early 2000s.

NewsHow Zika virus knocks out our immune defenses
Scientists have made striking discoveries regarding the different infection mechanisms of Zika and dengue virus of the same viral family. These understandings pave the way for vaccine development to combat flaviviruses with similarities.

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.
