Numerous investigations have shown that COVID-19 is a zoonotic illness that has been transmitted from animals to people through a Trusted Source. According to a new study, the notion that the epidemic originated in a marketplace rather than a laboratory is more likely to be correct.
The authors also explore if African swine fever may have had a part in the spillover event that resulted in the COVID-19 pandemic, which is a novel point of discussion. Researchers from the University of Glasgow in the United Kingdom have conducted a new investigation into the origins of the COVID-19 epidemic in the People’s Republic of China.
COVID-19 Have Been Rendered More Probable By African Swine Fever
Their results corroborate previous research that suggested an “intermediate animal host” may have been responsible for the transmission of SARS-CoV-2 to humans. Aspects of the study also consider the potential that an African swine fever epidemic contributed to the creation of an environment in which diseases had greater chances to spread from animals to people.
In addition to being a graduate student at the University of Glasgow’s Centre for Virus Research, Spyros Lytras also works in the pharmaceutical industry. His and his co-authors’ viewpoint article was published in the journal Science, and he was one of the writers.
The present article begins in 2002 with a discussion of the severe respiratory syndrome (acute) coronavirus (SARS-CoV), which first appeared in Foshan and spread to 29 different countries after being discovered there. Before all public health efforts stopped the spread of SARS-CoV in 2003, more than 8,000 individuals had acquired the virus.
The virus’s origins have been traced back to live market animals, according to experts. Researchers found in 2005 that horseshoe bats inside China were carrying coronaviruses that were linked to SARS (Severe Acute Respiratory Syndrome) (SARSr-CoVs). “It is possible that a (SARSr-CoV) prevalent in horseshoe bats spawned the progenitor of SARS-CoV in an intermediate animal host,” the researchers hypothesized. Badgers, civet cats, and raccoon dogs were investigated as potential carriers of the virus by scientists.
Civet cats were identified as the most probable carriers by the researchers. The possibility that a civet cat had been exposed to a SARSr-CoV before being captured was postulated by virologists. As an alternate explanation, it is possible that the virus was acquired by a caged civet cat from bats feeding in marketplaces.
The virus that causes COVID-19, SARS-CoV-2, first emerged in the Chinese city of Wuhan in 2019. A number of sources pointed to the Wuhan Institute of Virology as the origin of the epidemic. Indeed, Wuhan is more than 930 miles (1,500 kilometers) away from Yunnan Province, the closest known location of naturally occurring SARSr-CoV, which was obtained from horseshoe bats, according to the World Health Organization.
Furthermore, the viruses recovered in Yunnan were found to be “extremely divergent from the SARS-CoV-2 progenitor.”In their article, the authors express skepticism about the importance placed on bat colonies in Yunnan. According to the researchers, horseshoe bats have a broad geographic range, ranging from East China to West China and beyond. They also state that further sampling has shown the presence of other coronaviruses that are genetically related to SARS-CoV-2 and that are circulating within the horseshoe bats.
In addition, “several animal-market-associated spillover incidents” occurred in November and December of this year. According to the study, “the development of SARS-CoV-2 has characteristics that are compatible with a natural spillover of the virus.” Civet cats, Raccoon dogs, minks, and foxes are among the live species of animals sold at Wuhan markets vulnerable to SARS-related viruses, including civet cats and raccoon dogs, minks, and foxes.
According to Lytras and the colleagues he has, the Corona pandemic is the result of human interaction with living animals that were infected with the virus during the outbreak.
