ELI5: Why does our saliva taste different when we are down with illness?

Like a cold or fever.

Usually you are dehydrated and have more mucus than usual which will taste different. Also if your nose is stuffed, your smell ability is different. If you have a bacterial infection, there will be an odor from bacteria. And finally, antibiotics and other medicines can give you a strange taste in your mouth.
