That's not the case here.
Here Superflu is the name of an enormously infective disease.

This disease is not bad, no,
this is a good disease. And you may ask, what is a good disease?

A good disease is a disease which may cause a sense of well-being. Love is often a such disease, since it tends to be infectious.

But love is not always a good disease, as many know...
But I promise, Superflu is.
