Dette er en liste af de største kendte epidemier og pandemier, der er forårsaget af infektioner. Almindelige ikke-smitsomme sygdomme som hjerte-kar-sygdomme og kræft er ikke inkluderet. En epidemi er en hurtig spredning af en sygdom til et stort antal personer i en given population inden for en kort periode; for meningokokker, vil en smitterate, der overstiger 15 ud af 100.000 personer i to på hinanden følgende uger bliver betragtet som en epidemi.[1]
Igangværende pandemier er skrevet med fed. For en given epidemi bliver det gennemsnitlige antal døde brugt til rangeringen. Hvis dødstallet for to epidemier er det samme, vil den med den laveste afvigelse rangere højest. For historiske optegnelser af verdensbefolkningen se Verdens befolkning.[2][3]
Epidemier og pandemier med minst 1 millioner dødsfald
^ abcdThe estimates of global population at the time vary non-trivially (no consensus). The current estimates are based on the available population data from estimates of historical world population.[2][3]
^ abGlobal population changed significantly (not due to the epidemic) during the period of this epidemic.
^The governmental report of COVID-19 deaths is likely an undercount and is treated as the lower bound.[8] The academic upper bound is provided by Institute for Health Metrics and Evaluation, which agrees with the estimate of the World Health Organization on 21 May 2021 that the governmental number "would truly be two to three times higher."[9][10] In addition, the Economist keeps a daily estimate of the total excess deaths due to the pandemic (10–19 million as of 14 October 2021), including diseases other than COVID-19.[11]
^The COVID-19 pandemic started as a regional outbreak/epidemic of COVID-19 in China in late 2019. The World Health Organization declared it as a "pandemic" on 11 March 2020.[12] The starting time of this epidemic is thus 2019, regardless of the time when it was formally recognized as a pandemic.
^Epidemic typhus was not limited to Russia and several million citizens died in Poland and Romania. However, due to lack of exact data, only the Russian epidemic is included.
^ abcNo accurate data about the local population at the time of this epidemic.
