Disease & Prevention

📋 What it is

Germs cause many diseases; hygiene, vaccines and healthy habits prevent a lot of illness.

🗣️ Coach says

Many diseases are caused by germs — bacteria and viruses that spread person to person. The good news is prevention works: washing hands, covering coughs, clean water, good food and sleep, and vaccines that train the immune system all stop huge amounts of illness before it starts.
