Avian Flu and the Surveillance Function of the News Media: Intro: >>Avian flu remains a topic heavy with scientific uncertainty, yet high in potential risk. The virus occurs mainly in birds, but since late 2003, there have been 204 reported human cases, and 113 deaths. Most of these human infections have resulted from close contact with infected birds. Almost all of the cases have been reported in South Asia and China, though more recent infections have been reported in Iraq, Turkey, Egypt, and Azerbaijan. To date, according to the Centers for Disease Control (CDC), there is no evidence that the virus can spread from human to human. Yet because viruses evolve, scientists are concerned that Avian flu may eventually be able to move from one person to another. Officials fear that because there is little pre-existing immunity among humans to Avian flu, such a change could lead to a global flu pandemic, with potentially high rates of death, and major economic disruptions. According to the CDC, it is likely to be "many months" before an effective human vaccine can be developed, mass produced, and made widely available.
As scientists work to gain a better understanding of the threat, and U.S. health officials prepare for a possible domestic outbreak, public concern and perceptions will be shaped chiefly by news coverage. Yet how much coverage of Avian flu has there been in the media, especially in comparison to the SARS outbreak of 2002 and 2003, or in relation to other contemporary issues competing for the public's focus? Just how engaged and concerned is the public about Avian flu? And how is the public likely to make up its mind about the severity of the problem? Answers to these questions are important, since most health officials would prefer that the public be informed and concerned about the issue, but not alarmed.<<
