" New Zealand could have the highest occurrence of flu of anywhere in the world, if statistics from search engine Google are to be believed.
The number of people using Google for flu-related searches is higher in New Zealand than in other countries, and statisticians say there is a close relationship between people looking online for flu health advice and actual cases of flu.
"Of course, not every person who searches for 'flu' is actually sick, but a pattern emerges when all the flu-related search queries are added together," it says on google.org .
"We compared our query counts with traditional flu surveillance systems and found that many search queries tend to be popular exactly when flu season is happening."
