Poliomyelitis (the name it goes by in Poland, or acute Sudden Infantile Palsy) is caused by a virus called polio, which is transmitted by inhalation. Food or with infected objects. It is called the "silent intruder" because it invades the body and wreaks havoc.

About 20 years ago, victory was declared in the fight against the polio virus. Unfortunately, reports in recent months show that the virus has returned and is again attacking in various parts of the world.
