A layered approach is needed to prevent infections from becoming harder to treat — ScienceDaily

Counteracting antimicrobial resistance needs a multipronged approach, including training, labelling food products, working with the media and changing mindsets, according to a new study. Antimicrobial resistance occurs when bacteria, viruses, fungi and parasites change over time and no longer respond to medicines, making infections harder to treat and increasing the risk of disease spread, severe […]

Scientists develop ‘optimal strategies’ computer model that could significantly reduce future COVID-19 infections and deaths — ScienceDaily

A team of scientists from Nanyang Technological University, Singapore (NTU Singapore) has developed a predictive computer model that, when tested on real pandemic data, proposed strategies that would have reduced the rate of both COVID-19 infections and deaths by an average of 72 per cent, based on a sample from four countries. The model, called […]

Undocumented infections accounted for estimated three-quarters of infections last year — ScienceDaily

A new study published in the journal Nature estimates that 103 million Americans, or 31 percent of the U.S. population, had been infected with SARS-CoV-2 by the end of 2020. Columbia University Mailman School of Public Health researchers modeled the spread of the coronavirus, finding that fewer than one-quarter of infections (22%) were accounted for […]

New mathematical model incorporates human behavior — and the fears that drive it — to better predict multiple waves of infections — ScienceDaily

A new mathematical model for predicting infectious disease outbreaks incorporates fear — both of disease and of vaccines — to better understand how pandemics can occur in multiple waves of infections, like those we are seeing with COVID-19. The “Triple Contagion” model of disease and fears, developed by researchers at NYU School of Global Public […]

Whole-town study reveals more than 40% of COVID-19 infections had no symptoms — ScienceDaily

A study of COVID-19 in the quarantined Italian town of VĂ², where most of the population was tested, reveals the importance of asymptomatic cases. The authors of the new research, from the University of Padova and at Imperial College London, published today in Nature, suggest asymptomatic or pre-symptomatic people are an important factor in the […]

Millions of US workers at risk of infections on the job — ScienceDaily

A University of Washington researcher calculates that 14.4 million workers face exposure to infection once a week and 26.7 million at least once a month in the workplace, pointing to an important population needing protection as the novel coronavirus disease, COVID-19, continues to break out across the U.S. Marissa Baker, an assistant professor in the […]
