Orthoflavivirus circulation in South-East Queensland, Australia, before and during the 2021-2022 incursion of Japanese encephalitis virus assessed through sero-epidemiological survey of a sentinel equine population.

An incursion and outbreak of Japanese encephalitis virus (JEV) was reported in Australia in 2021 and 2022, respectively. There was speculation that JEV may have been circulating in Australia unknowingly prior to the detection. In this study, we determined sero-prevalence and transmission of West Nile virus (WNV), Murray Valley encephalitis virus (MVEV) and JEV, prior to and post JEV incursion in a sentinel equine population in south-east Queensland (SEQ), Australia, using blocking ELISAs (screening test) and virus neutralisation test (confirmatory).

Perceived Barriers and Facilitators of Behavioral-Health Modality Change Adoption During the COVID-19 Pandemic: A Systematic Review.

Introduction: During the Coronavirus Disease 2019 pandemic, there was a surge in demand for mental health services worldwide, presenting challenges for healthcare institutions as they navigated changes in policy and safety regulations. In the United States, this resulted in many behavioral health modality changes to remain in compliance with the Center for Disease Control guidelines. A growing body of literature has documented these, yet few explored barriers and facilitators affecting the adoption of these modality delivery changes.

Drosophila require both green and UV wavelengths for sun orientation but lack a time-compensated sun compass.

Celestial orientation and navigation are performed by many organisms in contexts as diverse as migration, nest finding and straight-line orientation. The vinegar fly, Drosophila melanogaster, performs menotaxis in response to celestial cues during tethered flight and can disperse more than 10 km under field conditions. However, we still do not understand how spectral components of celestial cues and pauses in flight impact heading direction in flies.
