Four illnesses are filling Minnesota hospitals, and health leaders are warning you that Minnesota is dealing with a "quad-demic."

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.

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.

Patients are piling up in Minnesota emergency rooms once again, but it’s not just from COVID-19. State health officials say influenza is making a comeback, combining with COVID, norovirus and respiratory syncytial virus (RSV) to put more pressure on Minnesota hospitals than they’ve faced since the end of the pandemic.

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