Emerging viruses are those "whose incidence in humans has increased in the past 2 decades or threatens to increase in the near future." This week's Topic in Depth focuses on sites related to viruses, particularly those that are considered "emerging."
The first site (1
) is an essay by Alison Jacobson of the University of Capetown that discusses some emerging and potentially emerging viruses, along with factors that contribute to the threat. From a US government interagency working group, the second report (2
) focuses on the responses to infectious disease outbreaks, including drugs, vaccines, and government response. A World Health Organization site (3
) highlights recent reports of infectious disease, archived by date and by disease. This ThinkQuest site (4
) gives a basic introduction to viruses and how they cause infections. An online virology tutorial (5
) by Ed Rybicki of the University of Cape Town serves as a lesson on the basics of virology for a more advanced student. The next two sites focus on the specifics of selected viruses. From the Institute for Molecular Virology (6
) comes a resource on Marburg and Ebola viruses, and from the National Biological Information Infrastructure (7
) is a site on West Nile Virus. The last resource (8
) is a scholarly journal from the Centers for Disease Control that presents some of the latest scientific research on emerging diseases.
