Rhina O'Virus is a mischievous rhinovirus who plays havoc in the nose of an unsuspecting little girl. Rhina sneaks into a building-a nose cell-with her special key and upon discovering the cell's copying machine, duplicates herself to make a new bunch of playmates. They jig and jiggle, wiggle and dance, and play hide-and-seek and Marco Polo until the police force attack-and then "Whoaaah-ah-ah-choo!" Now the little boy has caught a cold too! With enchanting narrative and delightful illustrations, this whimsical story describes the process of viral infection, the immune system's response, and the mechanisms of contagion through the common cold, providing an educational and fun learning experience for curious children.
