@Jrobhatch29 it was reported in the Telegraphy but I couldn't find a link to the study either, I wondered if anyone else had!

"Almost half the people living in an Austrian ski resort that was a major centre of the European coronavirus outbreak now have immunity, according to a new study released on Thursday.
Scientists from Innsbruck Medical University found antibodies to the virus in 42.4 per cent of people in Ischgl.
It is one of the highest coronavirus infection rates yet discovered anywhere in the world. A similar study in Geneva found antibodies in just 10 per cent of the population, while in the Italian ski resort of Val Gardena, it was 27 per cent.
“We believe super spreading events, such as those that took place in après-ski bars, made a significant contribution to the widespread spread,” said Prof Dorothee von Laer, the leader of the Ischgl study.
The scientists behind the new study claim it is the highest infection rate found anywhere in the world. A study in Bergamo released earlier this month found antibodies in 57 per cent of people in the Italian city, but the authors of the Ischgl study claim their research is based on more rigorous testing and a higher sample size."
"Research for the new study took place in April, after the resort had been closed to tourists and placed under quarantine"
"1,473 Ischgl residents took part in the study, accounting for 79 per cent of the village’s population.
The scientists followed a rigorous procedure. Blood samples underwent at least two antibody tests, and in some cases were tested four times to eliminate false positives."
