Here's a sobering thought: Wild birds — including city pigeons and ubiquitous Canada geese — carry 170 different types of bird flu. You know, all those viruses with the Hs and Ns in their names, like H1N1 and H5N1.
Only a dozen of these viruses have infected humans so far, but many of those have been deadly, and three of them have caused global flu pandemics.
Does every bird flu that leaps into people have the potential to turn into the next "big one" that spreads rapidly around the world?
Packages of frozen berries from Oregon-based Townsend Farms, labeled as "antioxident blend," are being investigated as the cause of a multi-state outbreak of hepatitis A, including a dozen cases in Colorado.
Colorado health officials are investigating a dozen cases of hepatitis A within the state, a number that could climb higher as time goes on.
