Our 50th episode of QuidelOrtho Science Bytes features Dr. Jonathan Temte, a leading public health expert, discussing how schools, families, and healthcare providers can stay ahead of respiratory illnesses this school year. As students return to classrooms, familiar viruses like flu, RSV, and COVID-19 often resurge.

Dr. Temte explains why symptoms alone can’t reliably distinguish between these illnesses and how rapid diagnostics are essential for early detection, accurate treatment, and preventing further spread.
