'Plausible' evidence that Covid may have been circulating in Italy in October 2019
Re-testing of blood samples has shown that coronavirus may have been circulating in Italy as early as October 2019, two months before China alerted the world to the new disease, researchers have claimed. The World Health Organization asked for further clarification from researchers at a cancer centre in Milan after they claimed last November that samples from cancer patients showed Covid may have been circulating for several months in northern Italy - even before the first cases were reported in China in November 2019. https://www.telegraph.co.uk/global-health/science-and-disease/plausible-evidence-covid-may-have-circulating-italy-october/
