Studies for antibodies distribution to parainfluenza and Respiratory Syncytial(R.S) viruses with 179 serum specimens which were collected from the normal population from less than 1 to 40 years and over old in Seoul City in 1977 has been carried out.
The used methods were hemagglutination-Inhibition (H-I) test for the parainfluenza virus, type 1, type 2, aand type 3 and Neutralization test for the R.S. virus. The results obtained were as follows;
1. Positive rates of H-I antibodies to parainfluenza viruses with total of 179 sera showed that 38% for type 1, 36% for type 2, and 55% for type 3 virus.
2. It was showed that H-I antibody positive rates and titers for parainfluenza virus types 1, 2 and 3 wer increased along with increased age groups.
3. Particularly, positive rates for type 3 of parainfluenza virus were increased from the low age groups and positive rates for type 1 and type 2 were delayed to increasing compared with type 3 antibody.
4. As fro the positive rates of neutralizing antibodies for R.S. virus indicated that 75% from among total of 179 sera and it was also showed clearly that positive rates and antibody titers were increased with increased ages and it was reached 100% of positive rate from above 40 years of ages.
5. Positive rates of neutralizing antibodies for R.S. virus by sex indicated that more than 10% of positive rate occurred from the female compared withe the male group.
