The species was merged with Rat coronavirus (discovered in 1970 [23]) and Puffinosis coronavirus (discovered in 1982 [59]) as Murine coronavirus in 2009. [60] 229E and OC43 were collectively named Human respiratory virus but merged as Human coronavirus 229E (HCoV-229E) in 2009. [61]

[49] Haemophilus influenzae is an opportunistic bacterium which commonly follows influenza infections; this led the eminent German bacteriologist Richard Pfeiffer (1858–1945) to incorrectly conclude ...
Graunt's analysis of causes of death is considered the beginning of the "theory of competing risks" which according to Daley and Gani [1] is "a theory that is now well established among modern epidemiologists". The earliest account of mathematical modelling of spread of disease was carried out in 1760 by Daniel Bernoulli.
The virus, which originated in Russia or Asia, was the first to be rapidly spread by people on trains and steamships. [192] A new strain of the virus emerged in 1918, and the subsequent pandemic of Spanish flu was one of the worst natural disasters in history. [192]
