Another common finding in SARS patients is a decrease in the number of lymphocytes circulating in the blood. [14] In the SARS outbreak of 2003, about 9% of patients with confirmed SARS-CoV-1 infection died. [15] The mortality rate was much higher for those over 60 years old, with mortality rates approaching 50% for this subset of patients. [15]
The major part of the outbreak lasted about 8 months, and the World Health Organization declared SARS contained on 5 July 2003. However, several SARS cases were reported until May 2004. [4] In late December 2019, SARS-CoV-2, a coronavirus in the same genus as the one that caused SARS, was discovered in Wuhan, Hubei, China.
The cave where they discovered their strain is only a kilometre from the nearest village." [4] [73] The virus was ephemeral and seasonal in bats. [74] In 2019, a similar virus to SARS caused a cluster of infections in Wuhan, eventually leading to the COVID-19 pandemic. A small number of cats and dogs tested positive for the virus during the ...
Another estimate suggests SARS-CoV-2 shares a common ancestor with bat coronavirus RmYN02 in about 1976. [172] SARS-CoV also possibly originated in around 1962 from the same horseshoe bats that harbours SARS-like coronaviruses. [116] It was transmitted humans in around 1998 (4.08 years prior to the outbreak in 2003). [173]

The timeline of the COVID-19 pandemic lists the articles containing the chronology and epidemiology of SARS-CoV-2, [1] the virus that causes the coronavirus disease 2019 and is responsible for the COVID-19 pandemic. The first human cases of COVID-19 occurred in Wuhan, People's Republic of China, on or about 17 November 2019. [2]
On January 20, Chinese authorities announced the confirmation that human-to-human transmission of the coronavirus had already occurred. [19] [20]The first recorded U.S. case of the new virus was also reported on January 20, in a 35-year-old American citizen traveling from Wuhan, China, to his home in Washington state.
SARS-CoV-2 is the seventh known coronavirus to infect people, after 229E, NL63, OC43, HKU1, MERS-CoV, and the original SARS-CoV. [105] Like the SARS-related coronavirus implicated in the 2003 SARS outbreak, SARS‑CoV‑2 is a member of the subgenus Sarbecovirus (beta-CoV lineage B). [106] [107] Coronaviruses undergo frequent recombination. [108]
