Data analysis by statistician David Spiegelhalter shows COVID-19 deaths closely follow the normal age-related risk of death from all other causes. The risk is highest for older adults, with a 12-13% higher death rate for each year older. In contrast, school children experience only a 2-day extra risk above the normal annual risk.
Researchers analyzed COVID-19 patients' blood samples, revealing a unique metabolic signature associated with acute inflammation, liver dysfunction, and increased risk of cardiovascular disease. The findings may lead to the development of a metabolite-based diagnostic test and inform post-COVID-19 care.
