The definition of "emerging" infectious diseases includes those diseases "whose incidences in humans has increased in the past 2 decades or threatens to increase in the near future." The journal of Emerging Infectious Diseases continues to be an invaluable resource for public health professionals, scholars, and others. On the journal's homepage, users can read over the current issue and take a look at all of the articles and various commentaries contained within. Visitors can also peruse the archive, which dates back to the journal's first issue in 1995. As with many online journals, visitors can sign up to receive their RSS feed and they even have a podcast archive. The podcasts are a nice bonus, and they include programs like "Strategies For Fighting Pandemic Flu in Developing Countries" and "The Mystery of Increased Hospitalization of Elderly Patients".
