Analysts at the University of Glasgow in the United Kingdom investigated how the COVID 19 pandemic in China occurred.
Their results support previous studies showing that ” intermediary animal hosts” may have initiated SARSCoV2 into humans.
This article also explains that the African swine fever epidemic may also contribute to the high likelihood of pathogens transmission from animals to humans.
African Swine Fever May Have Made COVID More Probable
The current article discusses Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV), which began in 2002 and appeared in Foshan, Guangdong Province, China, and has spread to 29 other countries.
More than 8,000 people were infected with SARS-CoV before public health operations stopped in 2003. Experts have associated the origin of the virus with live market animals.
In 2005, researchers found that Chinese horseshoe bats were carriers of the SARS-associated coronavirus (SARS-CoV).
They hypothesized that “[SARSrCoV] disseminating horseshoe bats seeded an intermediate animal host with SARS-CoV progenitor cells.” Scientists have identified badgers, civets, and raccoons as probable bearers of the virus.
They identified civets as the most likely sender. Virologists theorize that civets may have let out to SARSrCoV before capture. Another speculation is that captive civets may have developed the virus from market-feeding bats.
In 2019, SARSCoV2, a virus that causes COVID19, emerged in Wuhan, China. Some argue that the cause of the pandemic is the Wuhan Vase Institute.
Wuhan is around 1,500 km from Yunnan, the nearby known site for natural SARSrCoV harvested from horseshoe-shaped bats. In addition, the virus collected in Yunnan was “very different from the predecessor of SARSCoV2.” In their treatise, the author casts doubt on the emphasis on bat population in Yunnan.
They elucidate that the geographical range of horseshoe-shaped bats is diverse, from eastern to western China and beyond.
They also describe that additional sampling recognized other coronaviruses genetically close to SARSCoV2 circulating in horseshoe-shaped bats. The first case of SARSCoV2 exposed at the end of 2019 was related to the wet market from a reliable source in Wuhan.
In November and December 2019, Various spillover events related to animal markets also occurred.
The article explains that the emergence of SARSCoV2 has properties compatible with natural spills. Among the various live animals on the Wuhan market, raccoon dogs, civets, foxes, and ferrets are highly susceptible to SARS-related viruses.
It is concluded that the COVID-19 was by human contact with live animals carrying the virus.
The article also speculates that changes in China’s meat supply may have influenced the spread of SARSCoV2. African swine fever is a hemorrhagic fever, usually lethal in pigs but harmless to humans.
In 2018, an outburst of African swine fever killed 150 million pigs. As a result, the following year was a scarcity of pork and an increase in prices.
The manufacturing and sale of meat from other animals such as cows and chickens are increasing but are not sufficient to make up for the scarcity.
As a result, the authors of the new paper said: “Food consumers and manufacturers may have relied on meat substitutes, including wildlife captured or captured from China, where wildlife is eaten, and especially wild animals.
