Flu season is hanging on longer than usual in parts of the Northwest. That’s shown in cases of the flu -- and also via web searches. Google queries for terms like “muscle aches,” ”flu symptoms” and “thermometer” are being used to track where flu is hitting now.
Google and the Centers for Disease Control have found that flu-related searches go hand-in-hand with confirmed cases of the flu. Up-to-the-minute data is available on the web for anyone to track at a site called Google Flu Trends.
