The flu is caused by a sneaky little influenza virus that loves to travel from person to person. When someone who has the flu coughs or sneezes, tiny droplets in the air carry the virus with them, and if you breathe those in, poof, you're now infected too. The virus multiplies inside your body, making you feel sick and giving you a runny nose, sore throat, and chills. That’s why the flu spreads so fast: it just needs one sneeze or cough to move on to the next person.
Examples
- Influenza virus particles float through the air when a sick person coughs, making infection easy for everyone nearby.
- When someone with the flu sneezes, tiny droplets filled with the virus escape, and you might breathe one in.
- The virus replication process is like a tiny army taking over your body, that’s why you feel so sick.
