  • (Syndromic) Surveillance of Birthweight, Gestation, and Infant Mortality

    Content Type: Abstract

    There is a great deal of interest in spatial patterns of infant mortality. However, small numbers can make spatial patterns difficult to discern and may mask areas of persistently high risk. This study investigates the spatial pattern of birthweight… read more

Additionally, spatial patterns of mortality may be driven largely by spatial patterns of demographic …
  • Influenza Surveillance Using Wearable Mobile Health Devices

    Content Type: Abstract

    Influenza surveillance has been a major focus of Data Science efforts to use novel data sources in population and public health. This interest reflects the public health utility of timely identification of flu outbreaks and characterization of their… read more

  • Algorithms to Characterize Syndromic Surveillance Spatial Alerts

    Content Type: Abstract

    This paper explores some visualization methods for characterizing spatial signals detected by SaTScan and discusses how these maps might aid in deciding whether to investigate a signal, as well as the scope and focus of the investigation.

  • (Syndromic) Surveillance of Birthweight, Gestation, and Infant Mortality

    Content Type: Abstract

    This study uses data on births in New York City between 2000-2005 to investigate the spatial pattern of birthweight and gestation, two primary risk factors for infant mortality. The analysis uses SatScan to perform normal-distribution cluster… read more

  • Cluster Detection Incorporating Lagged Test Data

    Content Type: Abstract

    Using New York Cityís dead bird surveillance for West Nile Virus (WNV), this paper presents two explorations of the spatial cluster detection problem in which lagged test results are available for a random subset of observations. First, we… read more
    … within the system. Advances in public health informatics may eventually provide spatially-referenced lab data; some … pattern under the null hypothesis. Using recent data may result in WNV+ birds in the baseline, while using …
  • A Novel Application of Syndromic Methods of Monitor Temporal Changes in the Specificity of an Oral HIV Test

    Content Type: Abstract

    To apply syndromic techniques in assessing whether the false-positive rate (FP rate) of a rapid oral HIV test, routinely used for screening in New York Cityís STD clinics, deviated from the manufacturerís claim; results of which have important… read more
