On the downside, better context is needed. A graphic says 70,000 people get sick a year, most not seriously. Is that good or bad, and compared to what? It seems like a significant omission.
At the same time, this story, at 4,800 words, is too long. Another write-through would have tightened it considerably, I have no doubt. Less is more. Don’t give anti-long-form-investigations forces any ammunition, I say.
