We made a clinical observation of 191 cases of measles at the pediatric department of Hanyang University Hospital during the period from May, 1972 to May, 1979. The results obtained were as follows: 1.The incidence of measles patients among the total pediatric patients was about 1% and the ratio of the unvaccinated and the vaccinated was 72 to 28. Recently, the annual incid-ence among the vaccinated group has markedly increased,the highset case being in the year1978.2.The age distribution of the incidence was highest among the group of ： one two years of age. No significant differene was shown between the vaccinacted and the unvaccinated group. 3.The sex incidence revealed male prominence with the ratio about 2 : 1. 4.The seasonal distribution was highest in spring (March-May). 5.The age of the first vaccination was most common in 8〜 12 months of age (63.9%). 6.The most common interval between the time of vaccination and the clinical onset was within 1 year after the first vaccination (34.3%). 7)There was no significant difference in the duration, of fever between the vaccinated and the unvaccinated. 8)The duration of rash among the unvaccinated group was noted to be longer, i.e.,5 days or more, than among the vaccinated group. 9.The average peripheral W.B.C. counts in the unvaccinated group were 10,925/mm3, which were significantly increased W.B.C. counts than the vaccinated group. 10.The complications were observed more in the unvaccinated group than the vaccinated group. The common complications of measles were pneumonia (39%) otitis media (14.1%), obstructive laryngitis or laryngotrachitis (9%), encephalopathy(2%), in this order.
