A Practitioner-Driven Research Agenda for Syndromic Surveillance.

Syndromic surveillance has expanded since 2001 in both scope and geographic reach and has benefited from research studies adapted from numerous disciplines. The practice of syndromic surveillance continues to evolve rapidly. The International Society for Disease Surveillance solicited input from its global surveillance network on key research questions, with the goal of improving syndromic surveillance practice.

Evaluating Google, Twitter, and Wikipedia as Tools for Influenza Surveillance Using Bayesian Change Point Analysis: A Comparative Analysis.

Background: Traditional influenza surveillance relies on influenza-like illness (ILI) syndrome that is reported by health care providers. It primarily captures individuals who seek medical care and misses those who do not. Recently, Web-based data sources have been studied for application to public health surveillance, as there is a growing number of people who search, post, and tweet about their illnesses before seeking medical care.

The Ratio of Emergency Department Visits for ILI to Seroprevalence of 2009 Pandemic Influenza A (H1N1) Virus Infection, Florida, 2009.

Background: A seroprevalence survey carried out in four counties in the Tampa Bay area of Florida provided an estimate of cumulative incidence of infection due to the 2009 influenza A (H1N1) as of the end of that year's pandemic in the four counties from which seroprevalence data were obtained Methods. Excess emergency department (ED) visits for influenza-like illness (ILI) during the pandemic period (compared to four non-pandemic years) were estimated using the ESSENCE-FL syndromic surveillance system for the four-county area.

Results: There were an estimated 44 infections for every ILI ED visit.

Antimicrobial stewardship programs in Florida's acute care facilities.

We surveyed acute care facilities in Florida to assess components of and barriers to sustained antimicrobial stewardship programs (ASPs). Most respondents with and without ASPs are doing some stewardship-related activities to improve antimicrobial use. Collaborative efforts between facilities and health departments are important to providing better resources for ASPs.

A comparison of two delivery modalities of a mobile phone-based assessment for serious mental illness: native smartphone application vs text-messaging only implementations.

Background: Mobile phone-based assessment may represent a cost-effective and clinically effective method of monitoring psychotic symptoms in real-time. There are several software options, including the use of native smartphone applications and text messages (short message service, SMS). Little is known about the strengths and limitations of these two approaches in monitoring symptoms in individuals with serious mental illness.

"Blueprint version 2.0": updating public health surveillance for the 21st century.

Rapid changes to the United States public health system challenge the current strategic approach to surveillance. During 2011, the Council of State and Territorial Epidemiologists convened national experts to reassess public health surveillance in the United States and update surveillance strategies that were published in a 1996 report and endorsed by the Council of State and Territorial Epidemiologists. Although surveillance goals, historical influences, and most methods have not changed, surveillance is being transformed by 3 influences: public health information and preparedness as national security issues; new information technologies; and health care reform.

Prevalence of 2009 pandemic influenza A (H1N1) virus antibodies, Tampa Bay Florida--November-December, 2009.

Background: In 2009, a novel influenza virus (2009 pandemic influenza A (H1N1) virus (pH1N1)) caused significant disease in the United States. Most states, including Florida, experienced a large fall wave of disease from September through November, after which disease activity decreased substantially. We determined the prevalence of antibodies due to the pH1N1 virus in Florida after influenza activity had peaked and estimated the proportion of the population infected with pH1N1 virus during the pandemic.

Sauvons le Luxembourg: urban greenspace as private domain and public battleground, 1865-1867.

This article examines the way in which public response to a municipal proposal concerning greenspace reduction in Paris during the Second Empire reflected not only political antipathy but also an ever-increasing understanding of public urban greenspace as part of the private domain. By examining archival records concerning the proposal, essays, newspaper accounts, and memoirs, this article argues that a particular proprietary sensibility, fomented by expansive public greenspace development in Paris, intersected with extant social constructs and political tensions to create a public, coordinated, and sustained challenge to the authoritarian regime. Thus, the battle over the Luxembourg Garden became more than just a fight to prevent a reduction in size of a particular public urban greenspace.

Pertussis in Florida, 2000-2006: trends in a historically low-incidence state.

Objective: Florida, the fourth most populous state in the nation, has had historically low incidence rates of pertussis, the only vaccine-preventable disease with increasing numbers of reported cases. We compared the epidemiology and incidence rates of pertussis in Florida with other states and the United States.

Methods: We used Florida and federal surveillance data from 2000 through 2006.

PHSkb: a knowledgebase to support notifiable disease surveillance.

Background: Notifiable disease surveillance in the United States is predominantly a passive process that is often limited by poor timeliness and low sensitivity. Interoperable tools are needed that interact more seamlessly with existing clinical and laboratory data to improve notifiable disease surveillance.

Description: The Public Health Surveillance Knowledgebase (PHSkb) is a computer database designed to provide quick, easy access to domain knowledge regarding notifiable diseases and conditions in the United States.

Summary of notifiable diseases--United States, 2003.

The Summary of Notifiable Diseases--United States, 2003 contains the official statistics, in tabular and graphic form, for the reported occurrence of nationally notifiable diseases in the United States for 2003. Unless otherwise noted, the data are final totals for 2003 reported as of June 30, 2004. These statistics are collected and compiled from reports sent by state health departments to the National Notifiable Diseases Surveillance System (NNDSS), which is operated by CDC in collaboration with the Council of State and Territorial Epidemiologists (CSTE).

Design and operation of state and local infectious disease surveillance systems.

Since 2001, increased attention has been focused on improving acute infectious disease surveillance systems. This article describes options for their design and operation. Systems designed primarily to detect individual cases of reportable diseases may differ from those designed to detect outbreaks or support design or evaluation of control programs.

Pseudoepidemic of Q fever at an animal research facility.

Serum samples from people exposed to sheep at a research facility were evaluated by a commercial laboratory and resulted in an overall Coxiella burnetii seroprevalence of 75%. We interviewed individuals to determine exposure history and compatible illness, and retested their sera. Analysis indicated that the commercial laboratory was misinterpreting its results; when corrected, the seroprevalence dropped to 27%.

Framework for evaluating public health surveillance systems for early detection of outbreaks: recommendations from the CDC Working Group.

The threat of terrorism and high-profile disease outbreaks has drawn attention to public health surveillance systems for early detection of outbreaks. State and local health departments are enhancing existing surveillance systems and developing new systems to better detect outbreaks through public health surveillance. However, information is limited about the usefulness of surveillance systems for outbreak detection or the best ways to support this function.

SARS preparedness checklist for state and local health officials.

A planning checklist for widespread severe acute respiratory syndrome, modeled on an Association of State and Territorial Health Officials (ASTHO) pandemic influenza planning checklist, was developed jointly by ASTHO, the National Association of County and City Health Officials, and the Centers for Disease Control and Prevention. This checklist, distributed May 2003, has been widely used.

Nosocomial transmission of hepatitis C virus associated with the use of multidose saline vials.

Objective: To identify the source of an outbreak of acute hepatitis C virus (HCV) infection among 3 patients occurring within 8 weeks of hospitalization in the same ward of a Florida hospital during November 1998.

Design: A retrospective cohort study was conducted among 41 patients hospitalized between November 11 and 19, 1998. Patients' blood was tested for antibodies to HCV, and HCV RNA-positive samples were genotyped and sequenced.

Mass vaccination campaign following community outbreak of meningococcal disease.

During December 12-29, 1998, seven patients ages 2-18 years were diagnosed with serogroup C meningococcal disease in two neighboring Florida towns with 33,000 residents. We evaluated a mass vaccination campaign implemented to control the outbreak. We maintained vaccination logs and recorded the resources used in the campaign that targeted 2- to 22-year-old residents of the two towns.

Predicting death from HIV/AIDS: a case-control study from Florida public HIV/AIDS clinics.

Background: After markedly decreasing for 3 years, HIV/AIDS mortality declined only slightly in 1999.

Methods: The authors conducted a case-control study in four Florida urban public health HIV clinics to evaluate modifiable factors associated with HIV/AIDS mortality in a non-research setting. Structured chart review was conducted for 120 case-patients who died in 1999 and for 240 randomly selected control-patients.
