NewsWhat factors influence likelihood and severity of Ebola outbreaks?
Two new papers looked at factors that contribute to how Ebola outbreaks begin and how severe they become. This Q&A looks at how the results could inform public health interventions to prevent pathogen emergence or slow the spread of Ebola and other infectious diseases.

NewsTicks carrying more than one pathogen are on the rise in US Northeast
Tick-borne diseases are on the rise in the northeastern US, with many ticks carrying more than one pathogen. Most commonly found together were Borrelia burgdorferi and Babesia microti. Co-infection with these two pathogens was more frequent than expected, approaching 11% by the end of the study.

NewsRecent pandemic viruses jumped to humans without prior adaptation, study finds
A large-scale evolutionary analysis shows most zoonotic viruses emerge without prior adaptation, while passing through a laboratory leaves detectable genetic signatures, offering a new tool to interpret outbreak origins.

NewsArtificial feeding platform transforms study of ticks and their diseases
The world’s first lab-based tick feeding system for bush ticks has transformed the study of ticks and how they transmit disease. The novel, host-free technology reduces the need for animal experiments in tick studies, facilitating more ethical, reproducible research.

NewsNew study reveals how hygienic honey bees show unique advantages in fighting infectious pathogens in adult bees
For the first time, research shows that a key social trait in honey bees is linked to measurable physiological advantages that can improve colony survival. The study uncovers how hygienic honey bee colonies mount stronger individual immune defenses against Nosema ceranae.

NewsPig farm ammonia pollution may indirectly accelerate climate warming, new study finds
A new study shows that ammonia released from intensive livestock farms can significantly increase nearby soil emissions of nitrous oxide, a powerful greenhouse gas that contributes to climate change and ozone depletion.

NewsScientists identify more effective way to detect poultry viruses in live markets
Scientists have found that viruses circulating in live poultry markets can be detected more effectively by sampling the surrounding environment than by testing individual birds. The study shows that environmental sampling can uncover a broader range of poultry viruses.

NewsBig and small dogs both impact indoor air quality - just differently
An initial study reports that dogs — both big and small — impact indoor air quality. The researchers found that small active dogs produced more airborne particles, but larger animals released more microbes into the air than people did.

NewsImaging technique is step towards needed treatments for hantaviruses in new molecular ma
Researchers have produced a detailed blueprint, the highest resolution yet, for a protein complex the Andes virus uses to infect host cells. The new detailed structural information enabled the researchers to produce a vaccine candidate that caused mice to produce neutralizing antibodies against the Andes virus.

NewsStudy finds no evidence of persistent tick-borne infection in people who link chronic illness to ticks
When researchers studied Norwegians who thought tick bites caused their chronic health problems, they found no objective evidence linking the symptoms to ticks. The same study finds that health problems reported by participants were associated with little physical activity and low labour force participation.

NewsNew study finds sex and menopause-based differences in presentation of early Lyme disease
In a new study, researchers found that male and female patients with early Lyme disease present with different signs of the disease in the symptoms they report, their physical exams and their laboratory test results.

NewsScrub typhus a threat in the home, study in South India finds
Most human scrub typhus infections could occur inside villages rather than during agricultural work, suggests new research conducted with the help of communities living in Tamil Nadu.

NewsAntimicrobial resistance in foodborne bacteria remains a public health concern in Europe
Antimicrobial resistance (AMR) in common foodborne bacteria such as Salmonella and Campylobacter continues to be a public health concern across Europe, according to a new joint report from EFSA and ECDC.

NewsDebilitating virus can spread in cool weather, increasing health risk in Europe
Chikungunya virus, a debilitating tropical disease caused by infected mosquito bites, poses a greater health threat in Europe than previously thought because it can be spread when air temperatures are as low as 13 degrees Celsius.

NewsMpox: recombinant virus with genomic elements of clades Ib and IIb
Recombination of monkeypox virus (MPXV) strains has been documented in recent months, with two cases of a recombinant strain comprising clade Ib and IIb MPXV reported, the World Health Organization says.

NewsFire-footed rope squirrels identified as a natural reservoir for monkeypox virus
A cross-species transmission event documented in Côte d’Ivoire provides new insights into the spread of mpox in the wild.

NewsResearchers develop simple at-home tests for detecting cat and dog viruses
Researchers report improved lateral flow assays for at-home screening of cats and dogs. In tests on veterinary clinic samples, the assays demonstrated 100% sensitivity and reproducibility for both feline parvovirus and canine parvovirus.

NewsH5N1 causes die-off of Antarctic skuas
More than 50 skuas in Antarctica died from the high pathogenicity avian influenza virus H5N1 in the summers of 2023 and 2024, marking the first documented die-off of wildlife from the virus on the continent.

NewsPathogen risk: Removing southern African fences may help wildlife, boost economy
Fences intended to protect cattle from catching diseases from wildlife and other livestock in southern Africa are in disrepair, restrict wild animal migrations and likely intensify human-elephant conflict – but a plan to remove key sections could make both livestock and wildlife safer.

NewsResearchers on the cusp of a vaccine for a global health threat
Researchers are on the cusp of a new vaccine to prevent chikungunya, a global health threat which attacks human joint tissue. The team tested whether they could engineer E. coli to assemble biopolymer particles which displayed chikungunya antigens and performed as a vaccine.
