A team of Israeli scientists have concluded that the United States was the Zionist entity’s biggest source of coronavirus by far, after running genomic sequencing on the virus.
The research team, which was drawn from nine institutions, also found that once the virus reached the Zionist entity, a small number of “super spreaders” were responsible for the large majority of infections, Times of Israel reported.
Seven out of every 10 Israelis who caught the virus to date were infected with a haplotype — variant — that arrived in the Zionist entity from the United States, Tel Aviv University evolutionary virologist Adi Stern, who led the study, told The Times of Israel.
She said that just 30 percent of people who arrived in the Zionist entity during the crisis came from America, so she was “very surprised” by how widely their haplotypes of the virus spread. She thinks it may reflect, in part, the unusually high level of interaction that Jewish visitors from the Diaspora have with Israeli citizens.
The pattern of the spread was also surprising, she said. “We think that about 5% of the infected population spread the virus in 80% of cases,” Stern revealed, explaining this means that just 800 people are believed to be responsible for four out of five Israeli virus cases.
This is suggested by the fact that numerous patients have genomes of the virus that are 100% identical, “and we would expect far more variety if there was a more varied transmission chain,” Stern said.
“We know that everyone isn’t equal in terms of how much people spread viruses, and normally there’s an assumption that 20% of people spread 80% of the virus,” she said. “But this thinking cannot explain what we’re seeing here.”
