CDC: Flu subsides across US
Visits to doctors for flu-like illness, hospitalizations for lab-confirmed flu, and the proportion of deaths attributable to pneumonia and influenza all continue to decline in the United States or have leveled off, the Centers for Disease Control and Prevention (CDC) said today. No flu-related deaths among children were reported in the past week.

Tests by manufacturers, a government body, and independent experts have found no contamination. Authorities said the cases may be a statistical artifact of many more shots being given than in past years; Western Australia, where the cases have occurred, has administered 2 million doses.
