Active surveillance, including the use of a Remote Surveillance Trailer in San Pedro CA, involves actively searching for cases through a notification system or through a systematic protocol, such as calling all health departments in a region during a disease outbreak. The benefits of using an active surveillance system mean that a security breach is responded to quickly and effectively, reducing the impact of an event and, hopefully, saving the organization money. For diseases that can be prevented by vaccination, passive surveillance is the most common method, although active surveillance may be necessary in special surveillance situations. The use of data standards facilitates the comparability of surveillance information over time (for example, measuring the effect of programmatic interventions), between different surveillance approaches (for example, reporting at centers compared to sample surveys) and between countries and regions. Passive surveillance is the collection of data from those who voluntarily report it, such as hospitals, healthcare providers, parents, or health departments.
In addition, FETP graduates are hired as project surveillance officers at the state level to coordinate the surveillance activities of hundreds of local health workers in all states. Surveillance needs vary in the pre-impact, and post-impact phases (Binder and Sanderson 198). The collection strategies and the results of surveillance systems vary by state and can provide immediate data, for example, during ongoing investigations, or it may take weeks before passive reporting of data on some diseases is available. Surveillance activities are essential to detect diseases that can be prevented by vaccination and to obtain information that help to control or address a problem.
CCTV monitoring plays a crucial role in active security surveillance by providing continuous video surveillance of a specific area or location. In the specialized field of biological terrorism surveillance, syndromic surveillance refers to the active surveillance of syndromes that may be caused by potential agents used by biological terrorists and sometimes refers to alternative measures, such as increasing the use of over-the-counter medications or increasing calls to emergency departments. A subcategory of passive surveillance is “enhanced passive surveillance,” in which the organization receiving the data works closely with healthcare providers and laboratories most likely to report a particular disease or group of diseases and establishes systems to increase the timeliness and integrity of reporting. Not only does this improved level of oversight act as a deterrent to potential criminals, it also ensures that any suspicious or dangerous activity is quickly identified and addressed.
Most of the CCTV systems you see are an example of passive surveillance: they keep visual records that can be used later. When using CCTV in this passive way, care must be taken to ensure that the camera provides the information it needs. The principle is that different public health objectives and the actions needed to achieve them require different information systems. The type of action that can be taken, when or how often that action should be taken, what information is needed to take or monitor the action, and when or how often the information is needed should determine the type of surveillance or health information system (box 53,.
