ROME (Reuters) - More than half the residents tested in Italy’s northern province of Bergamo have COVID-19 antibodies, health authorities said on Monday, citing a sample survey.
Of 9,965 residents who had blood tests between April 23 and June 3, 57% had antibodies indicating they had come into contact with the coronavirus, the survey showed.
Health authorities in Bergamo said the results were based on a “random” sample which was “sufficiently broad” to be a reliable indicator of how many people had been infected in the province, which became the epicentre of Italy’s outbreak.
In a separate statement issued later, the Bergamo health agency said that most of those in the sample were residents of the worst-hit areas. Many had already been put under quarantine, the statement added.

In a report released in early May, national statistics institute ISTAT said the number of deaths in Bergamo was up 568% in March compared with the 2015-2019 average, making it Italy’s worst-hit city in terms of deaths.
