What is the difference between infection, disease, illness, etc.?

Viruses and bacteria cause infections. Almost every thing else is a disease.

@RedDeerGuy1 Thanks. What is a good link?

@flo Sorry I don’t know. You can try MedMD.

@RedDeerGuy1 Alright.

One week ago, it says your last post but I just got it today.

Infection occurs when any micro-organism such as bacteria, viruses enters your body. Disease is a condition, which produces specific symptoms and is diagnosed by a medical expert. An illness is mostly based on self-reported symptoms.

Ok. @TerenceBlacker, If you would post link, would be great.
