Polio, abortive

A minor form of infection with the polio virus, abortive polio accounts for 80 to 90 percent of clinically apparent cases in the US, chiefly occurring in young children.

The usual symptoms emerge three to five days after exposure to the virus, and include slight fever, malaise, headache, sore throat, and vomiting.

Full recovery occurs in 24 to 72 hours.

It does not involve the nervous system or permanent disabilities of any kind.

The word 'abortive' here means 'tending to cut short.' Abortive polio is polio cut short.
