Which type of health insurance covers a group whose composition is continuously changing?

Blanket health insurance is designed to provide coverage for a group of individuals whose membership or composition can change frequently. This type of policy is typically used for groups that are temporary or have fluctuating membership, such as students in a school setting, participants in an event, or travelers. The dynamic nature of the covered group means that blanket health insurance can adapt to the varying needs of its members without requiring individual policies for each person.

In contrast, group health insurance usually pertains to a defined group of people who have a stable membership, such as employees of a company. Short-term insurance is intended for coverage over a limited period and does not cater specifically to changing group dynamics. Comprehensive health insurance offers extensive coverage but is typically not tied to a group whose membership fluctuates. Therefore, blanket health insurance stands out as the most appropriate choice for covering a group with an ever-changing composition.
