Findings indicate that deaths resulting from COVID are a quarter of those seen in previous waves, but experts say this should be handled with caution.
Results project a wave of COVID-19 transmission for all scenarios considered, with varying levels of infections, hospital admissions, and mortality
Cross-protection from seasonal epidemics of human coronaviruses (HCoVs) has been hypothesized to contribute to the relative sparing of children during the early phase of the pandemic. Testing this relies on understanding the prepandemic age distribution of recent HCoV infections, but little is known about their dynamics. Using England and Wales as a case study, we use a transmission model to estimate the duration of immunity to seasonal coronaviruses, and show how cross-protection could have affected the age distribution of susceptibility during the first wave, and could alter SARS-CoV-2 trans...
The Omicron variant has been designated a variant of concern, two years since the pandemic started, prompting questions about what the future holds.
SARS-CoV-2 infection risks during mass childhood vaccination campaigns can be greatly reduced by adequate personal protective equipment (PPE), symptomatic screening and appropriate campaign timing, according to new research in BMC Medicine.
