	Human challenge study reveals lasting cognitive decline after mild COVID-19 Researchers from the UK conducted the first human challenge study of SARS-CoV-2, revealing long-lasting cognitive deficits in unvaccinated participants infected with the virus, especially in memory and executive function.

	Study offers insights into chronic fatigue syndrome and its resemblance to long COVID-19 The study, which will serve "as a guide for rapid diagnosis", provides valuable information for the medical community, in particular in primary care.

			Long COVID patients maintain robust immune memory two years after infection Researchers discovered that SARS-CoV-2-specific T and B cells in long COVID patients are maintained for two years, similar to fully recovered individuals, offering insights into long-term immunity.

			New research strengthens the case for a zoonotic origin of COVID-19 A new international collaborative study provides a list of the wildlife species present at the market from which SARS-CoV-2, the virus responsible for the COVID-19 pandemic, most likely arose in late 2019. The study is based on a new analysis of metatranscriptomic data released by the Chinese Center for Disease Control and Prevention (CDC).

			Researchers identify new oscillatory patterns in COVID-19 cases across the U.S. Researchers discovered previously unrecognized oscillatory trends in COVID-19 cases across the U.S., particularly a north-south oscillation around the 37°-38° north latitude. These patterns highlight the complexity of pandemic dynamics and the importance of understanding regional disease transmission.

	Nearly half of people older adults plan to get the updated COVID-19 vaccine, poll suggests The newly updated COVID-19 vaccine just arrived in pharmacies and clinics nationwide, and a new poll suggests nearly half of people age 50 and older plan to get it.

	Florida’s new covid booster guidance is straight-up misinformation In what has become a pattern of spreading vaccine misinformation, the Florida health department is telling older Floridians and others at highest risk from covid-19 to avoid most booster shots, saying they are potentially dangerous.

	U.S. health system underperforms despite massive spending, while Australia and the Netherlands excel A recent Commonwealth Fund report compares health systems across 10 countries, revealing that the U.S. ranks last overall despite high healthcare spending, with significant gaps in health outcomes, equity, and access to care.

	AI-driven urban planning models mislead public health interventions, study shows AI models using Google Street View (GSV) for urban planning can lead to incorrect conclusions about public health, especially regarding obesity and diabetes. The study reveals that physical activity levels, not environmental features like sidewalks, are more impactful on health outcomes.

	Drug-resistant SARS-CoV-2 variants found in immunocompromised patients Individuals with compromised immunity and persistent COVID-19 infections can harbor drug-resistant variants of the SARS-CoV-2 virus, which have the potential to spread to the general population found researchers at Weill Cornell Medicine, the College of Veterinary Medicine at Cornell University and the National Institutes of Health's (NIH) National Institute of Allergy and Infectious Diseases (NIAID).

	Incidence and risk factors of an invasive fungal lung infection among COVID-19 patients Study reveals 0.4%-2.7% incidence of COVID-19-associated pulmonary aspergillosis in severe patients, highlighting significant mortality risks and risk factors.

	New method identifies biomarkers in wastewater using origami-paper sensors Researchers at Cranfield University have developed an innovative new method for identifying biomarkers in wastewater using origami-paper sensors, enabling the tracking of infectious diseases using the camera in a mobile phone.

	Global fight against antimicrobial resistance sees surge in deaths among older adults Comprehensive study estimates the global antimicrobial resistance (AMR) burden from 1990 to 2021, identifying significant age and regional disparities. It highlights future AMR death projections and underscores the importance of prevention and new antibiotic development.

	Research reveals a disconnect between patient expectations and care for long COVID "Long COVID" is the continuation or development of new symptoms three months after initial SARS-CoV-2 infection.

	Researchers analyze incidence of COVID-19-associated pulmonary aspergillosis in Japan As society learns to live with COVID-19, research on the disease and its complications remains important.

	Machine learning early warning system reduces non-palliative deaths in general medicine unit A study on CHARTwatch reveals its effectiveness in predicting patient deterioration, leading to reduced non-palliative care mortality in general medicine units.

	Study identifies wildlife species likely involved in the origin of SARS-CoV-2 A new international study provides a shortlist of the wildlife species present at the market from which SARS-CoV-2, the virus responsible for the COVID-19 pandemic, most likely arose in late 2019.

	Janus particles enable highly precise measurements in microfluidic devices The importance of testing for diseases was thrust into the limelight during the COVID-19 pandemic. Many of us have undergone a PCR (Polymerase Chain Reaction) or ELISA (Enzyme-Linked Immunosorbent Assay) test within the past four years.

	Study shows no increased autism risk for pandemic-era children Children born during the first year of the pandemic, including those exposed to COVID in utero, were no more likely to screen positive for autism than unexposed or pre-pandemic children, found researchers from Columbia University Vagelos College of Physicians and Surgeons.

	Epidemiology of viral pathogens involved in febrile rash illness Announcing a new article publication for Zoonoses journal. The aim of this study was to monitor the spectrum of viral pathogens involved in febrile rash illness (FRI) and their epidemiology.
