Virgo-itis is most often caused by people that infect the home with filth and disease, resulting in increased behavior that is typical of a virgo. Often times caused by others who lack basic hygienic skills.
Sudden bursts of cleaning(which last for hours) also cleaning while no one is home.
Treatment for acute virgo-itis is simply to let the behavior run it's course and allow yourself to clean for hours on end as there is currently no cure in sight.
I wish I could get rid of this virgoitis I have so that I can talk to my friends!
Wow! Look how clean it is in here! Looks like someone got a case of virgoitis!
