Salmonella in the Caribbean (CB1167)

	Salmonella montage

For years, Salmonella was a pathogen of public health concern in the Caribbean. Because of limited resources, however, the problem received inadequate attention. When outbreaks of diarrhea occurred among tourists at luxury hotels in the region, staff from the Caribbean Epidemiology Centre (CAREC) collaborated with the ministries of health from the affected countries (agricultural and tourism agencies) to find the source.

  • How do case characteristics provide clues to the problem?
  • What studies should be undertaken?
  • What can be done to control the problem?

Work through this case study and help CAREC find the answers to these questions and more.

Font Resizing Instructions

Once you install and run the case study, if you find that the text on the case study notebook appears to be cut-off (e.g., you do not see complete sentences or some of the content seems to be missing), it is likely that you are not using standard fonts in your computer settings. This is easily remedied with the following steps:

  1. Select Start from your Windows desktop (located in the lower left-hand corner of your computer screen).
  2. Point to Settings, and select Control Panel. NOTE: the specific titles for these choices will vary depending on your operating system.
  3. In the Control Panel window, double-click on the Display icon.
  4. In the Display Properties window, select the Settings tab.
  5. Select the button labeled Advanced located at the bottom right of the window. Be sure that the General tab is selected.
  6. Use the pull-down menu to change the Display Font Size to "Small Fonts".
  7. You will be prompted to install the new fonts and restart your computer to apply the changes. To return your computer to its original settings, follow the same series of steps but substitute your original font setting for the "Small Fonts" in Step 6.
