We are delighted that you are able to attend our annual conference, which highlights the professional activities of EIS Officers. The scientific program this year includes 95 oral presentations and 31 poster presentations. In addition, your experience this week will be enriched by International Night, the EIS skit, the Prediction Run, special award presentations, and other activities that have long been a tradition at the EIS Conference. In reading last year’s note, I see that I referred to 2004 as “The Year of the Flood” and spoke about the tsunami in South East Asia and the multiple hurricanes that had battered Florida and the Caribbean. Little did I realize that last year’s hurricane season was merely a warm-up for Katrina and Rita. As you would expect, EIS Officers figured prominently in all aspects of CDC’s response to these amazing natural disasters. Officers deployed to the disas- ter sites helped establish surveillance for injuries and illness in the affected areas, conducted needs assessments among displaced persons, investigated disease outbreaks, and temporarily replaced local public health workers forced by the storms to evacuate. As an added bonus to their training experience, the current cohort of EIS Officers often worked closely with the military in the affected areas, and consequently, they became much more familiar than previous EIS Officers with when, where, and how to salute. This was especially true for the EIS Officers billeted on the Marine Corps amphibious landing ship, Iwo Jima, anchored just offshore from New Orleans. During the 6 weeks after Katrina’s landfall, EIS Officers participated in 105 field deployments and another 18 assignments to the CDC Director’s Emergency Operations Center. Speaking of the new officers, we extend a special welcome to the incoming members of the EIS Class of 2006. The incoming officers are a select group of men and women with a broad array of interests and skills. Fifty-two (63%) of the new officers are women, and 11 (13%) are citizens of other nations. The countries represented this year are Ar- menia, the Bahamas, Belgium, Brazil, China, Germany, Great Britain, Italy, and Uzbekistan. Among the 71 who are U.S. citizens, 21 (30%) represent racial and ethnic minority groups. The class includes 39 physicians, 24 doctoral- level scientists, 12 veterinarians, four nurses, one physician assistant, one naturopath, and one MD/DVM. This year, we will again be running concurrent oral sessions on Tuesday and Wednesday mornings, so please check your program carefully. Several special sessions are also scheduled for this year’s conference. At lunchtime on Tuesday, a session featuring “Disasters and Chronic Diseases” will be held, and again at lunchtime on Thursday, a special session will focus on “Pandemic Flu Preparedness.” This 2006 Conference provides you the opportunity to hear about many current applications of epidemiology to public health and prevention by EIS Officers. We welcome you to an exciting series of days and evenings in the EIS experience, an opportunity to learn, to meet old and new friends, and to welcome the incoming officers. I look forward to seeing you throughout these events.
