This is exactly related to the powerpoint but New York State has counted people who have died from Covid-19 into their total count even though they didn't test positive for it. How can they do this?
You do not need a test if the clinical presentation other tests clearly show COVID-19. For example, CT and x-rays show very distinct changes in someone with COVID-19 called a 'ground glass' appearance. You don't see this in any other disease (well, almost no other), so it is COVID-19
