Last week, we informed you that Johnson and Johnson and the FDA had begun to use YouTube as way to reach out to their clients. At EHealth, they tell us that the CDC has also joined and begun to use Web 2.0 to connect with their patients and doctors via the web. Through e-cards, the recipients receive ways to maintain a health lifestyle, and links to the CDC website where they can learn more about health. The also have a webpage for Widgets. The available widgets are CDC public health data and statistics, CDC seasonal flu updates and a CDC weekly influenza map.
