What are passive hazard surveillance methods?

Answer :

Final answer:

Passive hazard surveillance methods are systems where reports of diseases and injuries are received by health departments without actively seeking them out, relying on mandated reporting by various entities and prone to underreporting. Active surveillance involves proactive case seeking, yielding more complete data but at higher costs. Sentinel surveillance is a targeted form of passive surveillance used when specific, high-quality data are needed.

Explanation:

Passive hazard surveillance methods refer to the systems wherein health departments receive reports of suspected injuries or illnesses without actively seeking them out. These methods rely on health care providers, laboratories, schools, and other entities to send in case reports, which are mandated by law. The primary challenge with passive surveillance is the potential for underreporting because it depends on external parties to initiate reporting.

In contrast, active surveillance methods involve epidemiologists and other public health officials proactively seeking out cases of disease, especially during specific outbreak scenarios. Active surveillance tends to yield more complete data but requires significantly more resources, both in terms of personnel and finances.

Another strategy, sentinel surveillance, consists of case reporting from carefully selected sites, used when high-quality data are necessary, and passive methods are insufficient. For example, the genotyping of influenza viruses is performed using specimens from selected surveillance sites to inform the formulation of the annual influenza vaccine.
