Look for anyone loitering, especially in a car or van. … If the person you suspect is following you reacts quickly and changes their direction, this could indicate that you’re under surveillance.

What is an example of syndromic surveillance?
If the attack involved anthrax, for example, a syndromic surveillance system might detect a surge in influenza-like illness, thus, providing an early warning and a tool for monitoring an ongoing crisis.
What is a surveillance study?
Public health surveillance is “the ongoing, systematic collection, analysis, and interpretation of health-related data essential to planning, implementation, and evaluation of public health practice.” — Field Epidemiology.
What are the forms of surveillance?

What is surveillance and its types?
Public health departments at the federal, state, and local levels use different types of surveillance systems to promote health and prevent disease. These systems can be used to monitor disease trends and plan public health programs. There are two primary types of disease surveillance: passive and active.
What is an example of passive surveillance?

What is the disease surveillance?
Disease surveillance is an information-based activity involving the collection, analysis and interpretation of large volumes of data originating from a variety of sources. The information collated is then used in a number of ways to. Evaluate the effectiveness of control and preventative health measures.

What is passive surveillance?
Regular reporting of disease data by all institutions that see patients (or test specimens) and are part of a reporting network is called passive surveillance. There is no active search for cases. It involves passive notification by surveillance sites and reports are generated and sent by local staff.
What are the principles of surveillance?
Involves and encourages the community to report all cases of diseases and other health problems. Uses both active and passive surveillance for effective disease control and prevention.
