You see an insanely dangerous trajectory of cases taking off in March. But what exactly happened in March? The virus was introduced in Wuhan in November. And even without testing, we did detect a handful of cases here, the first known case being on January 21. So why would we suddenly experience the outbreak in March? It’s quite evident that the culprit for the spike in the chart is simply because that is when the testing began because Trump dropped the FDA regulation barring private testing after the government testing didn’t work.
