This Ain't Good

Lung damage appears to be far more common in H1N1 cases than it is in normal influenza, which is troubling, because the Spanish Influenza epidemic was characterized by fatal rapid onset pneumonia:

Study of about 70 fatal H1N1 cases so far also reveals there may be more incidences of co-infections with bacteria than was earlier thought, Dr. Sherif Zaki told The Canadian Press in an interview.

The damage to lung tissue is consistent with that inflicted by ARDS or acute respiratory distress symptom, Zaki says, referring to an often-fatal, difficult-to-treat syndrome that can have a number of causes. The U.S. National Heart, Lung and Blood Institute estimates about 30 per cent of people who develop ARDS die.

"In terms of the disease, yes, it (H1N1) is remarkably different than seasonal flu," Zaki says. "The pathology looks very similar to H5(N1)."

This winter will not be pretty.
