CDC: Four people infected with version of coronavirus seen in mink – Consumer Health News
TUESDAY, April 19, 2022 (HealthDay News) — At least four people in Michigan infected with a version of the coronavirus found primarily in mink are the first known cases of possible animal-to-human transmission of the virus in the United States.
The cases occurred in the first year of the pandemic and the US Centers for Disease Control and Prevention confirmed on Monday that they contained the same version of the coronavirus seen primarily in mink, The New York Times reported. Two of those infected worked at a Michigan mink farm where a coronavirus outbreak had occurred, while the other two had no known connection to the farm. The first three cases were reported Last year.
In early October 2020, Michigan officials announcement that the virus had been detected in mink from a local farm and that several of the animals had died. At the state’s request, the CDC sent a team to help investigate the outbreak. In March 2021, the CDC updated its website to note that a “small number of people” had contracted a version of the virus that “contained unique mutations linked to mink.” The temperature reported. “This suggests that spread from mink to humans could have occurred,” the agency said, noting that all human patients had recovered.
Samples of the virus taken from the four infected people showed two mutations previously identified in farmed mink in Europe and people associated with those farms. In November 2020, Danish officials culled thousands of mink because viral mutations seen in the animals posed a threat to future vaccine effectiveness.
“This, along with the fact that mink farm workers tested positive for COVID-19 after the mink herd began to get sick and increased mortality, suggests that the most likely hypothesis is that the workers became infected after contact with the mink on the farm,” Casey said. Barton Behravesh, DVM, director of the CDC One Health Office, said The temperature. However, she added that since “there is little genetic sequence available in the communities around the farm, it is impossible to know for sure whether the mutations came from the mink on the farm or were already circulating in the community.” .
