Abstract

|
The clinical analysis of 395 cases of paralytic poliomyelitis observed during five years period from Jan. 1965 to Dec. 1969, has been reported and compared with the previous studies done by Dr. Lim and Ko(1211 cases, 1954~1961) and Dr. Hur et al(322 cases, 1962~1964) at the Dept. of Pediatrics, Yonsei Univ. College of Medicine.
98.7% of the 395 cases were found to occur under the age of five years, 92. 5% under 3 years, with the highest peak by age occurring between 12 and 24 months(45. 1%). This picture of age distribution is similar to that found in the previous studies and is supposed to be one of the characteristics of the disease in Korea.
Taking the seasonal incidence into account it was found that 56.5% of the cases occurred in the summer from May to Sept.
However more sporadic cases were found to occur throughout the year than had previously been reported. The trend that the disease is more frequent in males than in females is consistent with the previous reports.
Looking at the vaccination status, it was found that 68.6% of the reported cases had not received vaccination, was the 20% remaining having received vaccinations irregularly and incompletely.
This fact present a very important problem in the aspects of child health in Korea, even though it indicates an improvement the vaccination status as compared with previous reports(78.2% had not received vaccinations in the previous reports.).
On the past histories, they had following diseases within the last 3 months before the onset, malnutrition, 34. 7%, Measles, 9.6%, chronic diarrhea, 6.1%, frequent URI, 7.1% and Chicken pox, 1.0%. Subsequently 58.3% of the cases were reported as abnormal growth and health.
The clinical picture of the initial symptoms which includes fever, 70.9%, cough, coryza, diarrhea and vomiting, is similar to that of previous reports.
