9 HOW LONG AFTER AN ACUTE POLIO INFECTION ARE THE SYMPTOMS OF THE LATE EFFECTS OF POLIO LIKELY TO APPEAR?

The time lag from the infection and its subsequent stable phase to the onset of new symptoms varies but is commonly reported to be about 30 years. It is not the age of the person as such that determines the beginning of this second phase but the time lapse from the infection (5).

The onset is usually slow and gradual. Clinical studies suggest that a very small but fairly steady neuromuscular decline takes place in all people who had polio but not all of them notice any symptoms (5,16).
