there's mention of it in the guardian's ticker. 5% nationally but more than 10% in Madrid.
also spotted that UK government has approved an antibody test and is negotiating to buy millions of them so I guess we will soon find out what the prevalence is here.
The news just said that spain had done a large antibody test on their population. Think around 60k random tests and found only 5% with antibodies.
Thats not great news considering the amount of deaths they have had ;/
Hopefully this data (or the representation by the news) Is missing some info that makes it look worse that it actually is.
