  • GPHIN is an early-warning system for potential public health threats worldwide. This includes CBRN&E related issues. GPHIN monitors over 10,000 global media sources in Arabic, Chinese (Simplified & Traditional), English, Farsi, French, Russian and Spanish. Monitoring in Portuguese is scheduled to begin in the next few months. News sources include national and local newspapers, newsletters, and journal abstracts. Relevant information is gathered and available to users in near-real-time and on a 24/7 basis. Non-English information is machine-translated to English and vice versa. The translation gives the essence of the subject being covered in the article. Using a password, GPHIN can be accessed anywhere there is internet access.
  • Traditional Hierarchical Paradigm: Events at the local level e.g. town or municipality are reported to the provincial level who then report to the federal level who then may or may not report it to the WHO. Time consuming and fraught with pitfalls .
  • GPHIN covers a broad range of public health issues as demonstrated by the examples listed on the right.
  • GPHIN also provides other types of information that is useful especially during a crisis. For example, during the SARS outbreak, GPHIN was able to provide information about the type of airport screening measures that were being implemented in countries around the world. We were able to give information about how the general public was feeling during the outbreak and what their concerns were which was important for our Minister’s office.
  • This graph shows the contribution of media as the most important initial source of information about disease events, providing 147/279 (53%) initial reports (Fig. 2). More than one third (91/279) were provided by official sources (national public health authorities or WHO networks), while the remaining 41 (15%) were provided by organizations of the United Nations, other governmental institutions, nongovernmental organizations and personal communications; these are designated as “Other” in Fig. 2.

  • en/Sheep with Sheep pox /NOT SMALLPOX
    • Article below is NOT AN ALERT, we did research and found that it was translated from a Greek article and the term smallpox was used instead of SHEEP POX (an error of the Newspaper).
      • Source: ERT Regions: Europe Place Name: Greece
      • Sheep with Smallpox
      • Smallpox cases have been located in a flock of sheep in Mandamados, Lesvos. The Lesvos Veterinary Department proceeded with the extermination and sanitary burial of the diseased animals. It also imposed the stock farm under ten-kilometre area quarantine. It is likely that the disease originated from the Turkish coast, where it has spread. The authorities have appealed to all stock breeders to report any smallpox cases to the local veterinaries immediately. Stock breeders, whose animals are put to death, are fully compensated. Scientists have ruled out the possibility of people to be infected from the disease.
