Yes, it would. King County WA (where I live) has around 2 million people. Assuming half of that get infected and 15% require hospitalization. That's 150k people flooding the hospitals. That is way WAY above what the hospitals can handle. And I'm not only talking about beds and ventilators. Think about road accidents or coronaries which happen at a known steady pace when it's business as usual. These cases require ambulances and quick response times which cannot be met anymore because the system is overloaded with covid-19 patients. What do you do? Turn the 60+ patients away?
