Voyage Trend Charts
Voyage Trend Charts are graphical representations of GI Illness rates for every GI Illness report by ship medical officeres to the Vessel Sanitation Program cruise since January 2001. Three carefully synchronized GI Illness trend lines are most valuable for seeing how the crew and passenger incidence rates climb and sink over successive cruises.
Voyage Trend Charts are PDF documents which describe the self-reported GI Illness Incidence in graphical format. The source of this information comes from the CDC VSP cruise ship GI Illness database in Atlanta, GA. Some PDF Time-Trend graphs span fifty to sixty pages of cruises.
Voyage Trend Charts allow a Cruise Ship Medical Officer to call up their ship, and see the complete history of voyages. A trained epidemiologist or physician will be able to interpret the level of interaction between the two populations, the perpensity of lingering disease in the crew, passenger, or both populations.

Target Audiences
Cruise ship medical and executive officers are the target audiences for this data. The strategy is to empower ship officers in controlling the spread of communicable GI Illness among crew and passengers in a proactive manner based on voyage history and retrospective disease analysis.
The statistics on this site are easily comprehended by a potential cruise passenger; but cruise ship medical officers and cruise line executives are urged to sudy the incidence of GI Illness on their cruise ships, cruise lines, and cruise ports and those of their competitors. The Vessel Sanitation Program has never released the bulk of the GI Illness information to the general public, but interpretation of the GI Illness data presented on this website can be extremely useful in increasing the effectiveness of the cruise industry risk management programs. Conversly, the public awareness of this data can divert potential passengers from cruise ships and cruise lines with a poor GI Illness Index to cruise ships with a better GI Illness Index.
Data Sources: CDC VSP GI Illness Data and Subsequent Data Analysis
The Centers for Disease Control, Vessel Sanitation Program, provides Disease Strategies with a periodic dump of the VSP Master Database containing the GI Illness reports from cruise ship medical officers since 2001. All GI Illness data on this website is self-reported to the Vessel Sanitation Program by the cruise ship medical staff or ship executive officers.
Disease Strategies acquires the data from the CDC VSP, cleans the dataset of obvious errors, corrects for data entry errors, and adds records that have been dropped over the last four years. The raw GI Illness data is placed into the Disease Strategies data warehouse, analyzed, interpreted, and presented on this website.
It should be noted that, Vessel Sanitation Program salaries and travel expenses are funded through cruise ship inspection and training fees through the Cruise Ship Industry, and not from the federal budget or the taxpayer. Surprisingly enough, because the CDC is not a regulatory agency, the Vessel Sanitation Program has no regulatory power so government employees of the CDC VSP can only make GI Illness risk management recommendations to the cruise lines and the final public health decisions are in the hands of the invidivual cruise lines.
