Prepare to be bored.
For every human cell we have in our body, there are 10 bacterial cells present on our body surfaces. Our body "surfaces" in this case also means our entire GI tract, from oral cavity to anus. So in a sense we are more bacteria than we are human.
Now, among the bacteria that live on us, most are either neutral, doing no harm to us but no good. Some are good; they live on us and due to content of the chemicals they release, they provide an environment that prohibits transient bacteria from surviving for very long. However, many of these are also opportunistic, meaning that if they get into our cells, they can cause disease. For example, we have billions and billions of E. coli living in our colon. They help protect against other normally pathogenic species but if they make their way into somewhere like the bladder, they can cause infection. The same goes with a host of other microbes that live on our skin. They're fine as long as they don't get into a cut, but if they do, infection can result.
With that in mind not all of us carry the same potentially pathogenic (disease causing) microbes. Each person's bacterial content is more or less unique to them. So say for example you scratched by some Khajit. His microflora is almost certainly different from yours and were the game accurate about diseases, our non-Khajit characters would probably come down with some pretty radical infectious diseases. The same goes with Argonians. I am not an expert on reptile microbiota but I do know that iguanas often carry salmonella.
All that said, if more realistic diseases were present in Skyrim we could do some pretty nefarious things. Sick of the population of Whiterun? Gather several gallons of the fetid standing water that's present throughout Tamriel and pour it in the well. Severe cholera can kill within days. Personally I'd just like a Dagger of Raging Diarrhea to nick Nazeem with.
