<p>A crucial metric in assessing a disease is the <a href="/wiki/Infection_fatality_rate" class="mw-redirect" title="Infection fatality rate">infection fatality ratio</a> (IFR), which is the cumulative number of deaths attributed to the disease divided by the cumulative number of infected individuals (including asymptomatic and undiagnosed infections).<sup id="cite_ref-fjMw6_84-0" class="reference"><a href="#cite_note-fjMw6-84">&#91;84&#93;</a></sup><sup id="cite_ref-WHOest_85-0" class="reference"><a href="#cite_note-WHOest-85">&#91;85&#93;</a></sup><sup id="cite_ref-ovoEx_86-0" class="reference"><a href="#cite_note-ovoEx-86">&#91;86&#93;</a></sup> Epidemiologists frequently refer to this metric as the 'infection fatality rate' to clarify that it is expressed in percentage points (not as a decimal).<sup id="cite_ref-87" class="reference"><a href="#cite_note-87">&#91;87&#93;</a></sup> Other published studies refer to this metric as the 'infection fatality risk'.<sup id="cite_ref-88" class="reference"><a href="#cite_note-88">&#91;88&#93;</a></sup><sup id="cite_ref-89" class="reference"><a href="#cite_note-89">&#91;89&#93;</a></sup>
</p><p>In November 2020, a review article in <a href="/wiki/Nature_(journal)" title="Nature (journal)"><i>Nature</i></a> reported estimates of population-weighted IFRs for various countries, excluding deaths in elderly care facilities, and found a median range of 0.24% to 1.49%.<sup id="cite_ref-90" class="reference"><a href="#cite_note-90">&#91;90&#93;</a></sup>
</p><p>Children and younger adults faced much lower IFRs (e.g., 0.002% at age 10 and 0.01% at age 25) compared with higher IFRs for older adults (0.4% at age 55, 1.4% at age 65, 4.6% at age 75, and 15% at age 85). These rates vary by a factor of ~10,000 across the age groups.<sup id="cite_ref-EJE_levinetal_83-1" class="reference"><a href="#cite_note-EJE_levinetal-83">&#91;83&#93;</a></sup> For comparison the risk for middle-aged adults of a fatal COVID-19 infection is two orders of magnitude more likely than the annualised risk of a fatal automobile accident and far more dangerous than seasonal influenza.<sup id="cite_ref-EJE_levinetal_83-2" class="reference"><a href="#cite_note-EJE_levinetal-83">&#91;83&#93;</a></sup>
</p><p>In December 2020, a systematic review and meta-analysis estimated that population-weighted IFR was 0.5% to 1% in some countries (France, Netherlands, New Zealand, and Portugal), 1% to 2% in other countries (Australia, England, Lithuania, and Spain), and about 2.5% in Italy; these estimates included fatalities in elderly care facilities.<sup id="cite_ref-EJE_levinetal_83-3" class="reference"><a href="#cite_note-EJE_levinetal-83">&#91;83&#93;</a></sup> This study reported that most of the differences reflected corresponding differences in the population's age structure and the age-specific pattern of infections.
