HCA 602 – Managerial Epidemiology National University October 2009 Marine Corps Recruit Depot is a Military training Command located in San Diego, California. Each month 500 young men are recruited and placed together in Recruit Enlisted quarters for the duration of their 12 weeks basictraining.

On September 18, 2009 after their graduation ceremony, a traditional dinner is served at the Mess Hall for the graduating Marine recruits, their family and training staff. An outbreak occurred among the 500 Marine recruit, their family and staff 8hours after having this dinner. 100 people became ill and common symptoms presented were dizziness, blurred vision, dry mouth, nausea and vomiting and diarrhea.All 100 people were admitted at the Naval Medical Center San Diego and further examinations were performed. After the examinations, these findings were discovered: 5 out of the 100 people examined also have ptosis, extraocular palsies, facial paralysis, palatal weakness and impaired gag reflex and 4 of them still have that partially healed superficial wound from their physical training few days ago.
