'A team of Israeli scientists have concluded that America was Israel’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 Israel, a small number of “super spreaders” were responsible for the large majority of infections.
Seven out of every 10 Israelis who caught the virus to date were infected with a haplotype — variant — that arrived in the country from the United States, Tel Aviv University evolutionary virologist Adi Stern, who led the study, told The Times of Israel.'
