@COVID19_disease Btw, its nearly immediate appearance in Europe in Dec 2019 is shown by @istsupsan (https://t.co/1DoTO3W6GI). And I wonder, 5 years later: Have we increased preparedness? Wastewater and environmental surveillance cannot be only a fig leave in a pandemic preparedness architecture!

@ruter_knekt Det verkar hur som helst orimligt med så hög andel som varit infekterade i september. Att virus gick att hitta i avloppsvatten i några norditalienska städer kring Lucia är något annat. https://t.co/6Zs39s9jqu

@EricMertz_KC @EacklesLedell @neontaster There are three published papers regarding pre-Wuhan coronavirus spread in Italy: https://t.co/OrFrCn4F95, https://t.co/fp7x3A8GY2, https://t.co/5dvjY1f692, and a preprint on Brazil: https://t.co/XNjgN5uzw8. So if you have any *evidence* to refute these, that'd be really cool.
