A80: Acute poliomyelitis

A80.4: Acute nonparalytic poliomyelitis

Polio is caused by viruses. These viruses may occur sporadically in some countries in Africa and South Asia. You can catch it by coming into contact with the saliva or excretions of an infected person.

The polio may only produce mild symptoms. If the symptoms are mild, you may get headaches, fever or a sore throat, for example. You may also have the urge to vomit. The skin's feeling may also be disturbed and muscles may be palsied.
