Relatively little is known about the long-term prognosis for patients with clinical West Nile virus (WNV) infection. We conducted a study to describe the recovery of New York City residents infected during the 1999 WNV encephalitis outbreak. Patients were interviewed by telephone on self-perceived health outcomes 6, 12, and 18 months after WNV illness(More)
In late summer 1999, the first domestically acquired human cases of WN encephalitis were documented in the USA. Aggressive vector-control and public education efforts by state and local public health officials limited the extent of human involvement. The discovery of virus-infected, overwintering mosquitoes during the winter of 1999-2000, predicted renewed(More)
On behalf of the National Biosurveillance Advisory Subcommittee (NBAS) and in keeping with our mandate to ensure that the federal government is enhancing state and local government public health surveillance capability, we are pleased to submit the "Improving the Nation's Ability to Detect and Respond to 21 st Century Urgent Health Threats; Second Report of(More)
BACKGROUND. When the 2009 H1N1 influenza A virus emerged in the United States, epidemiologic and clinical information about severe and fatal cases was limited. We report the first 47 fatal cases of 2009 H1N1 influenza in New York City. METHODS. The New York City Department of Health and Mental Hygiene conducted enhanced surveillance for hospitalizations and(More)
OBJECTIVE To investigate the association between socioeconomic status (SES) and hospitalization for 2009 H1N1 influenza, independently of access to care and known risk factors for severe influenza illness, among New York City residents during the 2009-2010 influenza season. DESIGN We used a 1:2 case-control study design, matching by age group and month of(More)
OBJECTIVE To investigate a mixed Salmonella heidelberg and Campylobacter jejuni foodborne outbreak in a nursing home. DESIGN Retrospective cohort study with a nested case-control design. Cases were defined by positive stool-culture results. Controls needed to be both asymptomatic and culture-negative. SETTING AND PATIENTS Residents of a 580-bed nursing(More)
OBJECTIVE We describe an effort to reduce transmission of a multidrug-resistant Streptococcus pneumoniae (MDRSP) in a long-term-care facility (LTCF). DESIGN Longitudinal cross-sectional study. SETTING An LTCF in New York City with ongoing disease due to an MDRSP strain among residents with AIDS since a 1995 outbreak. The MDRSP outbreak strain was(More)
The recent outbreaks of influenza A/H5N1 and 'swine influenza' A/H1N1 have caused global concern over the potential for a new influenza pandemic. Although it is impossible to predict when the next pandemic will occur, appropriate planning is still needed to maximize efficient use of resources and to minimize loss of life and productivity. Many tools now(More)
In 1998, the New York City Department of Health and the Mayor's Office of Emergency Management began monitoring the volume of ambulance dispatch calls as a surveillance tool for biologic terrorism. We adapted statistical techniques designed to measure excess influenza mortality and applied them to outbreak detection using ambulance dispatch data. Since(More)
OBJECTIVES To characterize risk factors associated with pneumococcal disease and asymptomatic colonization during an outbreak of multidrug-resistant Streptococcus pneumoniae (MDRSP) among AIDS patients in a long-term-care facility (LTCF), evaluate the efficacy of antimicrobial prophylaxis in eliminating MDRSP colonization, and describe the emergence of(More)
