I am delighted that you are able to attend our conference, which highlights the professional activities of EIS officers (EISOs) . The scientific program this year includes 95 oral presentations and 30 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 Conference . This year you might have noticed that CDC and EIS received a little more attention than usual in the popular media with the release of the movie Contagion (the conference program book design is a not so subtle acknowledgement of this attention) . It was fun to see Kate Winslet describe EISOs as “The Sherlock Holmes of the medical world ”. While the fictional world of EIS was being portrayed on the big screen, the real Sherlock Holmes were out in the field conducting a wide variety of investigations, which will be portrayed on the small screen in the conference ballroom . Looking forward, I predict that one of the themes for next year’s conference will be EISOs’ involvement in CDC’s renewed commitment toward eradicating polio . EIS alumni play critical leadership roles on the CDC teams coordinating and staff- ing this effort; EISOs will likely play an increased role on teams in the field as we get closer to reaching our goal . The first teams of EISOs began deploying in February and one of the special sessions this week will highlight their experiences . As always, we extend a special welcome to the incoming EISOs, members of the Class of 2012 . This year we again received about 475 applications . Although this continues to mean a lot more work for us in the initial screening process, it also means that we have a much richer pool of candidates from which to choose . I am confident that we have chosen an excel- lent group of new officers . This year’s 84 red name tags represent a select group of men and women with a broad array of interests and skills . Fifty- nine of the new officers are women (70%), and 13 are citizens of other nations (16%) . The other countries represented in this year’s class are Australia, Canada (3), Ghana, India, Israel, Japan, Kenya, Nigeria (2), Togo, and United Kingdom . Among the 73 U .S . citizens or permanent residents, 29 represent racial or ethnic minority groups (40%) . The class includes 26 PhD-level scientists (33%), 42 physicians (50%), 12 veterinarians (14%), 1 dentist, and 1 PharmD . One of the MDs and 3 of the DVMs also hold PhDs . Ten members of the class have accepted prematch assignments in state health departments . This year, we again will be running concurrent oral sessions on Tuesday and Wednesday mornings, so please check your program carefully . Several special sessions also will be included in this year’s conference . Tuesday’s lunchtime session is hosted by CGH and will focus on the Horn of Africa Famine: Applied Public Health in Nutritional Emergencies . On Wednesday, the National Center for Chronic Disease Prevention and Health Promotion will host a lunchtime session, Progress in Prevention and Control of the U .S . Childhood Obesity Epidemic: Creating Environments that Support Healthi- er Choices . On Thursday, our final special lunchtime session will cover Polio: EIS Response to a Public Health Emergency . The 2012 Conference provides you with an opportunity to learn about many current applications of epidemiology to public health and prevention by EISOs . I hope you enjoy this exciting series of days and evenings in the EIS experience, and I hope you take this as an opportunity to learn, meet old and new friends, and welcome the incoming officers . I look forward to seeing you during the week . Douglas H.
