Some more antibody tests were released in April (which I missed). I only previously covered two that took place in California. Two more in the US in New York and Miami, and another two in Italy and Germany.
Here are 4 other that again show a much higher percentage of the population (everywhere) has been infected, and this drastically drives down the death rate (globally).

Confirmation comes from Robbio, a town of about 6 thousand inhabitants in the province of Pavia where the mayor has decided to allow the population to carry out the blood test to evaluate both the positivity to Coronavirus and the possible presence of antibodies.
German study shows coronavirus might not be fatal as previously thought
Professor Hendrick Streeck, University of Bonn director of the Institute of Virology and Institute for HIV Research, joins 'Closing Bell' to discuss the university's antibody study and what it means for the coronavirus pandemic.
COVID-19 has affected an area of Germany where it's very concentrated. Gangelt has been compared as the Wuhan of Germany. It's estimated that 15% of the population has an infection with a case fatality rate of 0.37%. Streeck suggests this rate is similar across the globe.
