Epidemiological evidence of an early wave of the 1918 influenza pandemic in New York City.

The 1918 "Spanish flu" was the fastest spreading and most deadly influenza pandemic in recorded history. Hypotheses of its origin have been based on a limited collection of case and outbreak reports from before its recognized European emergence in the summer of 1918. These anecdotal accounts, however, remain insufficient for determining the early diffusion and impact of the pandemic virus. Using routinely collected monthly age-stratified mortality data, we show that an unmistakable shift in the age distribution of epidemic deaths occurred during the 1917/1918 influenza season in New York City. The timing, magnitude, and age distribution of this mortality shift provide strong evidence that an early wave of the pandemic virus was present in New York City during February-April 1918.

Immunoassay of infectious agents.

Immunoassays have evolved for a broad range of applications since the pioneering work of Yalow and Berson who developed the first competitive radioimmunoassay (RIA) for human insulin in 1959. Immunoassay detection of specific antigens and host-produced antibodies directed against such antigens consitutes one of the most widely used and successful methods for diagnosing infectious diseases (IDs). The number and variety of new assay systems that are continually being developed reflect the increasing demand for immunoassays possessing greater sensitivity, speed, and ease of use. This trend has been driven, in part, by the need for improved immunodiagnostic systems to perform rapid testing and counter emerging IDs and biothreat (BT) agents. Another factor driving this trend is the need to integrate immunoassays with more sensitive nucleic acid-based methods for a comprehensive approach. Here we examine the development of immunoassays, some of the key formats used for the detection and identification of BT/ID agents, and the application of these technologies under different scenarios.

Effectiveness of an emergency preparedness training program for public health nurses in New York City.

A public health workforce that is competent to respond to emergencies is extremely important. We report on the impact of a training program designed to prepare public health nurses to respond appropriately to emergencies. The program focused on the basic public health emergency preparedness competencies and the emergency response role of public health workers employed by the New York City School Department of Health and Mental Hygiene School Health Program. The evaluation methods included pre/post-testing followed by a repeat post-test one month after the program. The program resulted in positive shifts in both knowledge and emergency response attitudes.

Building academic-practice partnerships: the Center for Public Health Preparedness at the Columbia University Mailman School of Public Health, before and after 9/11.

The Center for Public Health Preparedness at the Columbia University Mailman School of Public Health is part of a national network of academic centers established by the Centers for Disease Control and Prevention to strengthen links between public health practice and academe, especially for public health workforce development. Since its inception in Fall 2000, the Center has been working in partnership with the New York City Department of Health & Mental Hygiene (DOHMH) on planning and competency-based training in emergency preparedness (including bioterrorism and infectious diseases) and evaluation. Initial programs with DOHMH included development of a 3-hour orientation to basic emergency preparedness for their workforce. In the wake of 9/11 and the anthrax events, Center members gave over two dozen presentations at community forums, seminars, and clinical rounds, and over 100 press interviews, provided lay language information through community forum presentations and the School's Web site, and developed a database of volunteers for surge capacity. Subsequent programs include bioterrorism response training for clinicians and emergency medical services personnel, incident command for public health, and a study of evacuation from the World Trade Center on 9/11.
