Occupational risks during a monkeypox outbreak, Wisconsin, 2003.

We determined factors associated with occupational transmission in Wisconsin during the 2003 outbreak of prairie dog--associated monkeypox virus infections. Our investigation included active contact surveillance, exposure-related interviews, and a veterinary facility cohort study. We identified 19 confirmed, 5 probable, and 3 suspected cases. Rash, headache, sweats, and fever were reported by > 80% of patients. Occupationally transmitted infections occurred in 12 veterinary staff, 2 pet store employees, and 2 animal distributors. The following were associated with illness: working directly with animal care (p = 0.002), being involved in prairie dog examination, caring for an animal within 6 feet of an ill prairie dog (p = 0.03), feeding an ill prairie dog (p = 0.002), and using an antihistamine (p = 0.04). Having never handled an ill prairie dog (p = 0.004) was protective. Veterinary staff used personal protective equipment sporadically. Our findings underscore the importance of standard veterinary infection-control guidelines.

The public health dashboard: a surveillance model for bioterrorism preparedness.

The City of Milwaukee Health Department piloted a short-term, near real-time syndromic surveillance and communication tool by using an existing secure regional Internet infrastructure. Voluntary, active syndromic case reporting by hospital Emergency Departments was combined with other data streams, including clinical laboratory reports of communicable disease, hospital emergency room diversions, ambulance runs, medical examiner reports of unusual or suspicious deaths, poison control and nursing hotline call volumes, and pharmacy over-the-counter sales. These data were aggregated into a "Surveillance Dashboard" format that was used to communicate community syndromic health trends to hospitals, Emergency Departments, and other providers using a secure Internet technology. Emergency Departments at 8 area hospitals reported a total of 314 cases meeting syndromic criteria from 26,888 patient encounters. Participants were satisfied with data entry and communications. All participating Emergency Departments received e-mail and text pager alerts sent by the Milwaukee Health Department. No unexplained findings or suggestions of an early outbreak were reported through syndrome surveillance for the 4-week duration of the project. Similar surveillance and communications systems could provide multiple benefits to Emergency Department workflow and management, as well as to public health and emergency response.

Three Hundred Sixty Degree Feedback: program implementation in a local health department.

Three Hundred Sixty Degree Feedback systems, while popular in business, have been less commonly implemented in local public health agencies. At the same time, they are effective methods of improving employee morale, work performance, organizational culture, and attainment of desired organizational outcomes. These systems can be purchased "off-the-shelf," or custom applications can be developed for a better fit with unique organizational needs. We describe the City of Milwaukee Health Department's successful experience customizing and implementing a 360-degree feedback system in the context of its ongoing total quality improvement efforts.

The detection of monkeypox in humans in the Western Hemisphere.

BACKGROUND: During May and June 2003, an outbreak of febrile illness with vesiculopustular eruptions occurred among persons in the midwestern United States who had had contact with ill pet prairie dogs obtained through a common distributor. Zoonotic transmission of a bacterial or viral pathogen was suspected. METHODS: We reviewed medical records, conducted interviews and examinations, and collected blood and tissue samples for analysis from 11 patients and one prairie dog. Histopathological and electron-microscopical examinations, microbiologic cultures, and molecular assays were performed to identify the etiologic agent. RESULTS: The initial Wisconsin cases evaluated in this outbreak occurred in five males and six females ranging in age from 3 to 43 years. All patients reported having direct contact with ill prairie dogs before experiencing a febrile illness with skin eruptions. We found immunohistochemical or ultrastructural evidence of poxvirus infection in skin-lesion tissue from four patients. Monkeypox virus was recovered in cell cultures of seven samples from patients and from the prairie dog. The virus was identified by detection of monkeypox-specific DNA sequences in tissues or isolates from six patients and the prairie dog. Epidemiologic investigation suggested that the prairie dogs had been exposed to at least one species of rodent recently imported into the United States from West Africa. CONCLUSIONS: Our investigation documents the isolation and identification of monkeypox virus from humans in the Western Hemisphere. Infection of humans was associated with direct contact with ill prairie dogs that were being kept or sold as pets.

SARS Surveillance Project--Internet-enabled multiregion surveillance for rapidly emerging disease.

INTRODUCTION: On March 15, 2003, CDC requested health-care and public health agencies to conduct surveillance for severe acute respiratory syndrome (SARS). The SARS Surveillance Project (SARS-SP) was established to rapidly implement multiregional SARS surveillance in emergency departments (EDs) by using existing Internet-based tools. OBJECTIVES: The objectives of SARS-SP were to 1) disseminate and update SARS screening forms for ED triage, 2) establish surveillance for SARS syndrome elements by using Regional Emergency Medicine Internet (REMI), 3) expand surveillance to multiple regions, and 4) evaluate the usefulness of Internet tools for agile surveillance during a rapidly emerging global epidemic. METHODS: SARS-SP developed, distributed, and updated an Internet-based triage form to identify patients for infection control and public health reporting. EDs then were invited to report visit frequencies with various SARS syndrome elements to local public health authorities by using the REMI Internet application (first in one metropolitan area, and later in four). After pilot-testing in one metropolitan area, the surveillance system was implemented in three others. RESULTS: Active syndromic surveillance was established by health departments in Milwaukee, Wisconsin; Denver, Colorado; Akron, Ohio; and Fort Worth, Texas. A total of 27 EDs reported syndrome frequencies from >146,000 patient encounters. CONCLUSIONS: ED and public health partners reported being satisfied with the system, confirming the usefulness of Internet tools in the rapid establishment of multiregion syndromic surveillance during an emerging global epidemic.

Assuring community emergency care capacity with collaborative Internet tools: the Milwaukee experience.

Hospital overcrowding and diversion of ambulances from emergency departments are being recognized as increasing problems in the health care system. This article, a descriptive narrative, examines the various factors contributing to the problem and describes how collaborative approaches to public health issues can be applied. It describes Milwaukee's experience with a collaborative approach. The use of a technological tool to assist with tracking and reporting on ambulance diversion and emergency department overload is explained, and data are provided to show the impact of various methods to blunt the impact of the flu season on diversion frequency. The article encourages use of similar collaborative approaches and Internet-based technology to address other public health problems.
