A team of scientists using a genetic sequence found that 205,000 to 300,000 cases of coronavirus in the US were linked to a “superspider” medical conference in Boston in late February.
The convention was previously thought to have involved about 20,000 cases in the Boston metro area, but researchers say it actually spread a lot after about 100 people caught the virus at the gathering.
Nov. 1 Meanwhile, in 51,000 cases around Boston, genetic markers were found in the strain of the virus associated with the conference.
It also spread to conference participants in other locations, including Florida, where 29 percent of the cases associated with the conference were completed; Indiana and North Carolina. According to research published in the journal Science, strains of the virus were found as far away as Australia, Australia and Slovakia.
“We don’t think this stress has a more diffuse growth than any other,” said Jacob Limiax, lead author of the study. “We suspect that such incidents are happening again and again, and are a major contributor to the spread of SARS-Cove 2 around the world.
Biogen said in a statement that the epidemic had had a “very direct and personal impact” on the company and hoped that the study would “continue to provide a better understanding of the virus’s transmission and efforts to prevent it.”
