So how bad was the H1N1 pandemic?
According to a new paper in PLoS Medicine, Marc Lipsitch's modelling estimates that among persons with symptomatic H1N1:
- 1 in 70 required hospital admission
- 1 in 400 required ICU care
- 1 in 2,000 died
With data in hand, he argues in an NPR piece that this is a very mild pandemic. Not so, says Dr. Tom Frieden, Director of the CDC. An expert in risk communication speculates that CDC is avoiding describing the pandemic as mild out of fears that vaccine uptake will fall.
