  • A collaboration to enhance detection of disease outbreaks clustered by time of patient arrival

    Content Type: Abstract

    One objective of public health surveillance is detecting disease outbreaks by looking for changes in the disease occurrence, so that control measures can be implemented and the spread of disease minimized. For this purpose, the… read more
