The coronavirus variant discovered in Britain is more easily spread among children, as it is among adults. Current safeguards should protect schools, experts said, but only if strictly enforced.
The Covid-19 pandemic has caused untold disruption and enhanced mortality rates around the world. Understanding the mechanisms for transmission of SARS-CoV-2 is key to preventing further spread but there is confusion over the meaning of “airborne” whenever transmission is discussed. Scientific ambivalence originates from evidence published many...
Stakeholders in public health must lobby policy makers to make decisions based on evidence, not political expediency, particularly when the studies that hang in the balance are critical to understanding the origins of epidemics.
Herd immunity is expected to arise when a virus cannot spread readily, because it encounters a population that has a level of immunity that reduces the number of individuals susceptible to infection. On page 288 of this issue, Buss et al. ([ 1 ][1]) describe the extent of the largely uncontrolled severe acute respiratory syndrome coronavirus 2...
Identifying drugs that regulate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and its symptoms has been a pressing area of investigation during the coronavirus disease 2019 (COVID-19) pandemic. Nonsteroidal anti-inflammatory drugs (NSAIDs), which are frequently used for the relief of pain and inflammation, could...
The first two vaccines proven to be effective for inhibiting COVID-19 illness were both mRNA, achieving 95% efficacy (and safety) among 74,000 participants (half receiving placebo) after intramuscular delivery of two shots, 3–4 weeks apart. To view this Bench to Bedside, open or download the PDF.
Global scientists are intensifying research into COVID-19, as the World Health Organization (WHO) moves to expand its scientific collaboration and monitoring of emerging variants of SARS-CoV-2, the virus that causes COVID-19.
In the age of the internet, there's no such thing as a private debate. But is that bad for science? Some scientists have had misgivings. When debates in any sector move beyond the halls of universities and government agencies, there is potential for misuse of information and public confusion. But open debate can also foster communication among...
