(2/3) The infection fatality ratio (IFR) was higher in males than females (1.07% vs. 0.71%).
When the IFR was calculated including deaths in care homes, and using excess all-cause mortality rather than confirmed #COVID19 deaths, the IFR was 1.58%.
(3/3) Antibody prevalence highest in people of black and Asian (south Asian) ethnicity, essential workers (particularly those with public-facing roles), and those living in deprived areas. Those working in health care (11.1%) & in care homes (15.1%) most likely to test positive.
12% IFR for age 75+ is horrible. Our politicians who advocate "herd immunity" are literally *decimating* our parents & granparents
