Astigmatism can be there before the age of 4. But it is the shape of the eye. If it is getting a lot worse suddenly, it could be something else, like Keratoconus. See your optometrist
Astigmatism is not a disease. It is genetically determined, thus inherited.  It is not an uncommon finding.  To correct the vision to compensate for astigmatism you need two lens powers, on sphere and a cylinder for the astigmatism. It only becomes a visual issue i the higher numbers.

It’s due to curvature of your cornea and lens, usually you are born with it.
Anatomical shape of the cornea.
