The radius is adjusted to geography, epidemiology, climate, and resources to control the epidemic.
➡️Restricted Zone
The area from the edge of the infected zone in a 10 km radius from the infected premise(s) for most diseases. It could extend as far as 60 km depending on the disease, method of spread, epidemiology, climate, geography, etc. Enhanced surveillance activities are in effect.

Includes the area between the restricted zone and the boundary of the control area.
