One cannot blame the Centers for Disease Control and Prevention if the official "FluView" app is a bit out of date. After all, they've been pretty busy the past month.
The free app is meant to be a window into the march of influence across the country. It features a map of the United States and a scale of reported cases (we in Pennsylvania apparently crossed into the hot zone just after New Year's) that the app's developer's promise to update weekly.
There's the rub: As of last week, statistics were available only through the week ending Jan. 5. For a better "view," go to the website at www.cdc.gov.
The app contains a lengthy disclaimer, stating, for example, that levels across the state aren't necessarily reflective of activity across entire states (if, say, just Pittsburgh and Philadelphia have large outbreaks, the entire state of Pennsylvania will be shown in bright red).
Still, if those alarming patterns are enough to make you wash your hands a bit more often, all the better.
