Key points:
1) Seroprevalance of antibodies in just 5% of the population in one of the hardest hit European countries
2) No difference in infection rates based on gender
3) Large variations in seroprevalence based on symptoms:
No symptoms - 2.8%; Several Symptoms - 12.3%; Loss of smell - 40.1%
Actual cases 8x the official count and IFR of just over 1%
This study is the largest yet and weakens the case for the pursuit of herd immunity without vaccines (28k fatalities with an infection rate of just 5%)
