study on the immunization activity of primary health care in control of poliomyelitis part I: Disease occurrence

ABSTRACT

Seroimmunological examination of all acute flaccid paralytic cases attending Alexandria's main pediatric hospitals in 1992 was done and their vaccination history was taken. It was revealed that 75% of the cases were from rural areas. The male to female ratio was 2.61 and 75% of the cases were below one year of age. Most of the paralytic cases were due to poliovirus 3 [65.4%], followed by poliovirus 1 [36.1%]. None of the fully immunized cases showed protective IgG antibodies against poliovirus 3 and 28.6% of them did not show any IgG against the 3 poliovirus strains
