Which of the following is a Regional Health Authority in Manitoba?

Southern Health is a Regional Health Authority in Manitoba that plays a significant role in the administration and delivery of health care services in that region. It encompasses a large area and is responsible for a range of health services including hospital care, long-term care, and community health services.

In the context of Manitoba, Regional Health Authorities were established to decentralize health care delivery, allowing for better management and responsiveness to local health needs. Southern Health, among others, was formed to ensure that health services align more closely with the specific health preferences and requirements of the populations they serve.

The other options listed do not pertain to established Regional Health Authorities in Manitoba. This emphasizes the distinct regionalization of health care services tailored to the needs of local communities, which is a vital component of effective health care delivery.
