People more often are origin of infectious diseases in animals than vice versa, data suggest
CIDRAP People pass twice as many viruses to domestic and wild animals than animals pass to people, concludes a study today in Nature Ecology & Evolution. University College London (UCL) researchers analyzed genomic data on nearly 12 million viruses in 32 viral families using network and evolutional analyses to characterize the mutations behind recent vertebrate species jumps. Most emerging and re-emerging […]

Ventilation Can Reduce Exposure to Respiratory Viruses in Indoor Spaces
CDC Levels of respiratory disease continue to decline nationally from the peak around late December. But even as we move past winter, it is important to remember that respiratory viruses are still spreading at elevated levels, with some spreading throughout the year. Ventilation can reduce respiratory virus transmission By using core strategies, like vaccination and practicing good hygiene, […]

Effectiveness of an Artificial Intelligence–Enabled Intervention for Detecting Clinical Deterioration
JAMA Question Is an artificial intelligence (AI) deterioration model–enabled intervention associated with a decreased risk of escalations in care during hospitalization? Findings In this cohort study of 9938 patients hospitalized at a single academic center in 2021 and 2022, exposure to the intervention was associated with a 10.4–percentage point absolute risk reduction in the primary composite outcome […]

A protein found in human sweat may protect against Lyme disease
MIT News Researchers also found that a variant of the protein is not as protective against the bacteria and increases susceptibility to the disease. Lyme disease, a bacterial infection transmitted by ticks, affects nearly half a million people in the United States every year. In most cases, antibiotics effectively clear the infection, but for some […]

Zika Vaccine Candidate Battles Brain Cancer
Precision Vaccinations Scientists from Duke-NUS Medical School (Duke-NUS) have developed a new approach using the Zika virus to destroy brain cancer cells and inhibit tumor growth while sparing healthy cells. Using Zika virus vaccine candidates developed at Duke-NUS, the team discovered how these strains target rapidly proliferating cells over mature cells—making them an ideal option […]

New antibodies target “dark side” of influenza virus protein
NIH NIH researchers explore hidden, vulnerable region of influenza neuraminidase. Researchers at the National Institutes of Health have identified antibodies targeting a hard-to-spot region of the influenza virus, shedding light on the relatively unexplored “dark side” of the neuraminidase (NA) protein head. The antibodies target a region of the NA protein that is common among […]

SARS-CoV-2 fragments may cause problems after infection
NIH Most COVID-19 cases are mild, but many still lead to life-threatening complications. Severe cases feature an overactive immune response that causes dangerous inflammation. This inflammation affects many different tissues and cell types, including uninfected ones, and resembles that seen in some autoimmune diseases. It’s not clear why SARS-CoV-2 can cause such inflammation while other […]

Deer Are Beta-Testing a Nightmare Disease
The Atlantic Prion diseases are poorly understood, and this one is devastating. Scott Napper, a biochemist and vaccinologist at the University of Saskatchewan, can easily envision humanity’s ultimate doomsday disease. The scourge would spread fast, but the progression of illness would be slow and subtle. With no immunity, treatments, or vaccines to halt its progress, […]

How bubonic plague rewired the human immune system
BBC Bubonic plague is still found in scattered locations around the world, but thanks to modern antibiotics it is far easier to treat than in the past. Yet, the disease may still have left its mark on humankind. Under the microscope, Yersinia pestis doesn’t look particularly special. It’s a fairly standard shape for a bacterium – a […]

The uncharted world of emerging pathogens
In their quest to detect early outbreaks, virus hunters are sampling environmental DNA in water, dirt, and air. It all started when Christopher Mason’s 3-year-old daughter licked a subway pole.Like any parent, he was horrified, but also keenly curious: What types of microbes might be clinging to a metal pipe gripped by countless commuters every […]
