Outbreak zoonotic diseases and diseases have spread throughout history. Common coronavirus infection (COVID-19) is one of the most serious pandemics in the world.
The coronavirus pandemic, caused by the acute acute respiratory coronavirus 2 (SARS-CoV-2) syndrome, first appeared in Wuhan City, China. The behavior in the seafood market, where wildlife trade takes place, was reported. The pangolin is one of the potential hosts of the virus, which may have acquired the virus from bats.
In addition to pangolins, camels, and civet cats, other hosts of the virus are minks.
Researchers at the U.S. Centers for Disease Control and Prevention (CDC) are reporting an outbreak of coronavirus infection (COVID-19) on mink farms in Utah, United States. They surveyed farms for evidence of openness and found high SARS-CoV-2 titers, suggesting a viral transmission pathway to native wildlife.
Wildlife epidemiologic study
The researchers described a wildlife epidemiologic study of mammals caught on or near buildings in Utah, where events of SAR-CoV-2 were thought to occur in mink that were cultivating.
Mink farming is a popular and popular industry in the US Most farms are family owned. Among the coronavirus pandemic, the U.S. Department of Agriculture Medical Services Laboratories confirmed SARS-CoV-2 infection in mink at two Utah farms in August 2020.
From there, more outbreaks were confirmed at many farms not only in Utah but also in Wisconsin, Michigan, and Oregon. Although epidemiologic studies are being processed, scientists believe that infectious farm workers are the potential source of the virus.
The study
To reach the study, published in the CDCs Emerging infectious diseases iris, the team captured free mobile mammals between August 22 and 30, 2020. They used Tomahawk and Sherman traps placed outside barns and barrier fences.
The team received oral, nasal, rectal swabs, blood samples, and tissue samples from the animals. All collected samples were sent to the National Veterinary Services laboratories, and printed samples were sent to the U.S. Geological Survey National Wildlife Health Center for testing.
SARS-CoV-2 viral RNA was tested in the samples by real-time transcription-polymerase chain reaction (RRT-PCR). Virus neutralization assays were used to validate serum samples.
In total, the team caught 102 mammals, 78 are rodents and 24 are mesocarnivores. Rodent species made up of 45 deer mice, 5 Peromyscus spp. Mice, 25 house mice, and 3 rock squirrels. Mesocarnivore species included escaped American mink, 2 American wild mink, 5 raccoons, and 6 striped scorpions.
Of the minks captured, 11 tested positive for SARS-CoV-2 antibodies. No other animals had any antibody responses. This means that the minks were previously exposed to SARS-CoV-2 and contracted the infection.
Of those minks with good results, three high bike thresholds were found.
“While we found no evidence for the establishment of SARS-CoV-2 in wildlife, the discovery of escaped mink has the potential to spread and interact with endangered wildlife. , such as wild mink or deer mice, are a cause for concern, “explained the researchers in the study.
Escapeing minks into the wild can be a threat to wild mink. Because they are susceptible to SARS-CoV-2 infection, they can become reservoirs of the virus. This could lead to a future outbreak of COVID-19, which has now caught more than 28.6 million cases in the U.S. alone, with more than 513,000 dying.
“Enhanced biosecurity and best management practices would help prevent the unintentional release of infected animals or the spillage of SARS-CoV-2 from species endangered to native wildlife,” he said. researchers.
Reverse zoonosis may play a role in the spread of viruses. It involves the transmission of a virus from humans to animals. As their spread could pose a health risk to humans and animals, it is vital that wildlife and mink farming are monitored.
