What Is a Virus?: Tiny Invaders and Your Amazing Defenders (What, How, Why — Big Questions for Curious Minds) - Tapa blanda

Sinopsis

A virus is so tiny you can't see it with your eyes. So how can something that small make an entire person sick?

Viruses are strange. They don't eat. They don't breathe. They can't even make more viruses on their own. Instead, they have to find a living cell, get inside, and use that cell to make copies of themselves.

But the human body isn't helpless.

What Is a Virus? — Tiny Invaders and Your Amazing Defenders takes children inside this microscopic battle to see what actually happens when a virus meets the human body.

Readers will discover how viruses enter cells, why they multiply, what makes us feel sick, and how the immune system recognizes trouble and fights back. They'll meet antibodies, immune cells, and the body's other tiny defenders—and see why getting better takes time.

Big, colorful illustrations turn things too small to see into a world children can explore.
