![]() There may be increased rates of smoking or comorbidities amongst the fatalities.There may be factors that account for increased death rates such as coinfection, more inadequate healthcare, patient demographics (i.e., older patients might be more prevalent in countries such as Italy).There may be delays between symptoms onset and deaths which can lead to underestimation of the CFR.Selection bias can mean those with severe disease are preferentially tested.The number of cases detected by testing will vary considerably by country.We still believe this to be the most appropriate for this context but have added an option to let users of this app explore how changing the method of weighting to Generalized linear mixed models ( GLMMs) impacts the prediction interval and estimated IFR.īetween countries, case Fatality rates vary significantly, and over time, which suggests considerable uncertainty over the exact case fatality rates. We previously reported estimates from meta-analyses using fixed-effect inverse-variance weighting. *case fatality rate is the number of reported deaths per number of reported cases (Updated 26th May) Estimates of heterogeneity and a 95% prediction interval are presented, but a pooled overall estimate is suppressed due to heterogeneity. We present country-level case fatality as a percentage along with 95% confidence intervals in a forest plot. ![]() Estimates from the cruise ship ‘Diamond Princess’ as well as countries with fewer than 1000 cases are excluded from the analysis. The proportion of deaths to the total numbers of cases was meta-analysed using the R function metaprop, using fixed-effect inverse-variance weighting. The total number of cases and the total number of deaths from COVID-19 outbreak data was drawn down (scraped) from. The IFR estimates the fatality rate in all those with infection: the detected disease (cases) and those with an undetected disease (asymptomatic and not tested group). It sets out the current Case Fatality Rate (CFR) estimates, the country-specific issues affecting the CFR, and provides a current best estimate of the CFR, and more importantly, the Infection Fatality Rate (IFR).
