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.

NewsResearch yields new model for replication of BKPyV virus, a major cause of kidney transplant failure
There are no effective antivirals against BK polyomavirus in transplanted kidneys. A better understanding of its replication will offer new ways to protect those kidneys.

NewsCleaning surfaces every two hours cuts norovirus infections by 83% in airports
At airports, frequently disinfecting surfaces, mask-wearing and antimicrobial surface coatings can all help prevent the spread of norovirus, according to a new study.

NewsMutation could facilitate H5N1 bird flu virus infection and potential transmission in humans
A recent study reveals that a single mutation in the H5N1 bird flu virus that has recently infected dairy cows in the U.S. could enhance the virus’ ability to attach to human cells, potentially increasing the risk of passing from person to person.

NewsCovid-19 virus can damage the retina - even without severe respiratory disease
An experimental study in mice shows that SARS-CoV-2 infection can damage the retinas, with long-term implications for vision.

NewsThe viral puzzle of why humans are susceptible to hepatitis B - but monkeys are not
Scientists collaborated to reveal the structural features of hepatitis B viral receptor homologue in macaques that restrict viral entry into their cells.

NewsStudy untangles how COVID-19 wreaks widespread damage in the body
A new study sheds light on the pathways that drive organ damage and death in severe COVID-19 and helps explain why survivors of the disease can experience long-term complications.

NewsPregnancy enhances natural immunity to block severe flu
Scientists discover a natural flu defense mechanism that activates in the nasal cavity during pregnancy.

NewsNanorobot hand made of DNA grabs viruses for diagnostics and blocks cell entry
A tiny, four-fingered ‘hand’ folded from a single piece of DNA can pick up the virus that causes COVID-19 for highly sensitive rapid detection and can even block viral particles from entering cells to infect them.

NewsCervical cancer deaths in young women plummet after introduction of HPV vaccine
Cervical cancer deaths have plunged dramatically among women under age 25, and researchers believe this is likely due to HPV vaccination.

NewsResearchers develop lysosomal TRAP for clearance of viruses and variants
Researchers have developed a novel lysosomal strategy for clearing viruses and their variants. This lysosomal ‘TRAP’ (lysoTRAP) shows potential for inhibiting infection by viruses and variants in cell, mouse, hamster, and human lung organoid models.

NewsWild boars could be a potential source of hepatitis E transmission to humans in the Barcelona metropolitan area
Scientists have identified a relevant molecular similarity between the hepatitis E virus (HEV) strains of wild boars in the metropolitan area of Barcelona and the citizens of this area, suggesting that these animals could be a source of human hepatitis E infections.

NewsResearchers develop a simple lab-free test to detect bacteria in fluids from water to urine
A novel new test for bacteria in fluids makes it as easy as observing a colour change to confirm the presence of disease-causing pathogens, promising much easier diagnostic tests and greater food safety.
