The client asked Zentropy to develop a website showcasing a new flu drug, Tamiflu. The drug must be taken by the patient 24 to 48 hours within the onset of flu symptoms. The client wanted the site to include interactivity as well as providing reasons for the users to return to the site. The objective was to drive flu sufferers to their doctors asking for a tamiflu prescription. The resulting site adhered to strict FDA regulations and included many interactive components including a symptom wheel that enabled users to decide whether they were experiencing the onset of the flu or just the common cold. In addition the site provided flu tracking technology that let the user enter their own zip code and see how many cases of the flu have been reported in their areas. The site also let users send e-cards informing friends and family that the flu was coming or get well cards to people with the flu. There was also flash animation that explained how Tamiflu helped to stop the spread of the flu. An interactive flu trivia game provided historical facts about the flu.
