Influenza (the flu) is a serious contagious respiratory illness caused by influenza viruses. Millions of people in the United States get the flu each year. Most people are sick for about a week. Some people (especially young children, pregnant women, older people, and people with chronic health problems) can get very sick and may die from the flu.

Google found that certain search terms are good indicators of flu activity. Google Flu Trends uses aggregated Google search data to estimate flu activity in your state up to two weeks faster than traditional systems.
