"I'm scared about what's going to happen this flu season because I don't think we've ever seen a coalition of multiple viruses kind of manifesting in this way before," said Dr. Elizabeth Clayborne, an emergency medicine doctor and associate professor at the University of Maryland School of Medicine.
If it seems like everyone around you is getting sick, you're not imagining it.
The flu season is hitting the United States unusually early and much harder than it usually does.
But now that much of America has abandoned preventive measures such as masking, more people are getting sick with seasonal illnesses.
Just like RSV, cases of flu started surging earlier this year, with the Centers for Disease Control and Prevention reporting at least 1,600,000 cases, 13,000 hospitalizations and 730 deaths as of Oct. 29, which is high for this early in a typical flu season.
