Zoonotic diseases generally refer to diseases of animal origin in which direct or vector mediated animal-to-human transmission is the usual source of human infection. Animal populations are the principal reservoir of the pathogen and horizontal infection in humans is rare.
In February 2021, after conducting part of their study, the WHO stated that the likely origin of COVID-19 was a zoonotic event from a virus circulating in bats, likely through another animal carrier, and that the time of transmission to humans was likely towards the end of 2019. [59]
SARS-CoV-2, the causative agent of COVID-19, was first introduced to humans through zoonosis (transmission of a pathogen to a human from an animal), and a zoonotic spillover event is the origin of SARS-CoV-2 that is considered most plausible by the scientific community.
A second line of evidence also supports the hypothesis that the pandemic had a so-called zoonotic origin, scientists said. Among the samples collected at the Huanan market on Jan. 1, 2020, the ...
Four other agencies have expressed “low confidence” in a zoonotic origin, meaning that they believe the coronavirus came from a wildlife market but lack the evidence to make a more definitive ...
Severe acute respiratory syndrome (SARS) is a viral respiratory disease of zoonotic origin caused by the virus SARS-CoV-1, the first identified strain of the SARS-related coronavirus. [3] The first known cases occurred in November 2002, and the syndrome caused the 2002–2004 SARS outbreak.
Epidemiological evidence suggested a zoonotic origin of the virus: more than 33% of the first detected cases of SARS in Guangdong corresponded to animal or food handlers. [17] Seroprevalence studies reinforced this zoonotic link (a high proportion of asymptomatic animal handlers at markets in Guangdong Province had antibodies against SARS-CoV ...
This claim would be more persuasive if Fauci had not stated over and over and over and over again, in media interviews, that he "strongly favored" the zoonotic origin theory; his subsequent ...
