There are several types of infection surveillance, including:
Passive Surveillance: This involves the routine reporting of cases by healthcare providers to public health authorities. It is the most common form of surveillance but may miss cases due to underreporting. Active Surveillance: In this approach, public health officials actively seek out cases, often through regular contact with healthcare facilities. This method is more resource-intensive but can provide more accurate data. Sentinel Surveillance: This involves monitoring a specific subset of the population or a particular geographical area to identify trends in diseases. Syndromic Surveillance: This method uses health-related data that precede diagnosis to identify potential outbreaks, such as monitoring emergency room visits for flu-like symptoms.
