<p>The types of surveillance are passive surveillance and active surveillance. Passive surveillance involves diseases being reported to health care providers and is simple and inexpensive but limited by incompleteness of reporting and variability of quality. Active surveillance involves health agencies contacting health providers seeking reports and ensures more complete reporting of conditions, but is more resource-intensive.</p> Signup and view all the answers

<p>Sentinel surveillance is the reporting of health events by selected health professionals to obtain high-quality data about a particular disease that cannot be obtained through a passive system. It can be used when monitoring trends or key health indicators, and involves only a limited network of carefully selected reporting sites.</p> Signup and view all the answers

<p>The advantages of sentinel surveillance include the ability to signal trends, identify outbreaks, and monitor the burden of disease in a community. It provides a rapid and economical alternative to other surveillance methods. However, it may not be as effective for detecting rare diseases or diseases that occur outside the catchment areas of the sentinel sites.</p> Signup and view all the answers
