The COVID-19 pandemic continues to constitute a huge threat to public health worldwide and despite the efforts and advances to untangle the mechanisms of SARS-CoV-2 infection and transmission among humans, we are still blind to the overall COVID-19 pathology and its consequences. The results presented in this paper might help understand the emergent erythropoiesis and
With the onset of the COVID-19 pandemic, social media has rapidly become a crucial communication tool for information generation, dissemination, and consumption. In this scoping review, were selected and examined peer-reviewed empirical studies relating to COVID-19 and social media during the first outbreak from November, 2019, to November, 2020. From an analysis of 81 studies,
A new study by Yale researchers found a significant association between the availability of hospital resources — particularly ICU beds — and patient mortality during the early weeks of the COVID-19 pandemic. This was especially true at hospitals in the northeastern U.S. which were hardest hit by the first surge of patient cases, according to
What is RNA? How do mRNA vaccines work, and how effective are they? What does this mean for the COVID-19 pandemic? In a short video, Yale experts Saad Omer, Onyema Ogbuagu, and Akiko Iwasaki explain the science.
A Russian vaccine against COVID-19 — Gam-COVID-Vac (dubbed “Sputnik V”) — shows 92% efficacy in interim results from a phase 3 trial reported in The Lancet. The two-dose vaccine uses replication-deficient adenoviruses to deliver a SARS-CoV-2 glycoprotein as the antigenic stimulus. Doses are administered at 21-day intervals, and the vaccine may be stored in normal freezers.
The ChAdOx1 nCoV-19 (AZD1222) vaccine has been approved for emergency use by the UK regulatory authority, MHRA, with a regimen of two standard doses given with an interval of between 4 and 12 weeks. The planned rollout in the UK will involve vaccinating people in high risk categories with their first dose immediately, and delivering
In one of the most puzzling and worrisome developments in the pandemic, scientists are racing to explain what’s happening in Manaus, Brazil, a city of 2.2 million at the edge of the country’s rainforest that is experiencing a second explosive outbreak, even though the first one was so bad it was thought to have produced
People infected with the new variant of covid-19 discovered in the South East of England (known as B.1.1.7 or VUI 202012/01) are more likely to have a cough, sore throat, fatigue, or myalgia than those infected with other variants, the Office for National Statistics has reported. The data, published 27 January, also show that people
Researchers at the University of Arizona are developing a COVID-19 testing method that uses a smartphone microscope to analyze saliva samples and deliver results in about 10 minutes. The UArizona research team, led by biomedical engineering professor Jeong-Yeol Yoon, aims to combine the speed of existing nasal swab antigen tests with the high accuracy of nasal swab PCR,
In the 14 studies with longitudinal data that reported information on the evolution of symptomatic status, nearly three quarters of persons who tested positive but had no symptoms at the time of testing remainedasymptomatic. Current data suggest that infected persons without symptoms—including both presymptomatic and asymptomatic persons—account for more than 40% of all SARS-CoV-2 transmission.
