A very sick illness like Covid-19 could happen again, and it's something we need to be prepared for.
The UK doesn't have enough special beds for very sick people, and that's a problem because we need those beds to keep people safe.
We need to have lots of doctors and nurses ready to help, and we need to learn new things about illnesses quickly so we know how to stop them.
It's also important to make sure everyone has equal chances to stay healthy, so everyone can be safe when a new illness comes along.
