Four illnesses are filling Minnesota hospitals, and health leaders are warning you that Minnesota is dealing with a "quad-demic." This year, Minnesota has already reached more than 700 hospitalized influenza cases.

Influenza A, COVID-19 and norovirus (stomach flu) are on the rise, according to the Centers for Disease Control and Prevention. But there's a fourth "bug" the public should be aware of: respiratory syncytial virus. RSV causes cold-like symptoms and affects the breathing passages and lungs.

Respiratory viruses are on the rise in Brevard, though not at a rate higher than previous years, according to local health systems.

As of Dec. 28, Michigan’s flu shot uptake -- less than 2.5 million doses -- sat far below its goal of 4 million doses administered. The state is behind where it was this time each of the last five years.

Across the nation, the healthcare system is taking a beating as the "quad-demic" continues to strain resources and slow down patient care. WCCO's Frankie McLister shows us how Minnesota hospitals are being affected.
