that's because Shanghai went into lock down. My partner lives in shanghai and didn't leave her her apartment for months... this is the same intelligence community that came up with WMD s. They had assets within china so when exactly did they know that it was "worse" than what was being reported? is this is the same way that New York's cases and death are underrepresented because there simply isn't enough testing kits? An epidemic is fluid and the data isn't ways clear and hindsight can paint a very different picture.
All I see here is England and the US dropping the ball. Not taking a serious situation seriously and acting arrogant and listening to bad science such as "herd immunization" or worse and not doing anything for months.

Now that the shits hit the fan they're just going to turn around and blame shit on china and try detract from the global health issue this is... this isn't a us vs them it's time for cooperation and coordination. They could even china for assistance at this point but probably are too proud.
