Abstract

BACKGROUND
Measles is a highly infectious disease throughout the world and has not yet been eradicated with aggressive vaccination in Korea since 1960's. Recently, measles outbreaks have occurred periodically every 2 to 4 years. Unlike measles in children, few clinical studies on the measles of adult in our domestic area were carried out. In this study, we analyzed epidemiologic and clinical features of adult measles patients. METHODS: From January to June in 2001, 23 adult measles patients were admitted in Sun general hospital in Daejeon. Epidemiologic findings, clinical course, and laboratory findings were reviewed retrospectively. RESULTS: Measles was predominant in male patients (M : F=2.3 : 1). Many of the patients were late teenagers and early twenties. Major symptoms were fever (100%), cough (100%), rash (100%), diarrhea (69.6%), vomiting (60.9%), headache (60.9%), rhinorrhea (30.4%), and sore throat (30.4%). Koplik spot was observed in 11 (47.8%) patients. Rash appeared 1-6 days after the onset of fever. Fever lasted for 5-9 days and cough lasted for 10-14 days. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were elevated in 12 (52.2%) and 9 (39.1%) patients, respectively. Only 14 (60.9%) patients were seropositive for measles specific IgG antibody, but all the patients were seropositive for measles specific IgM antibody. No fatal complication was observed. CONCLUSION: Gastrointestinal symptom and hepatic dysfunction were the clinical characteristics of adult measles outbreak in Daejeon, 2001. Different from previous studies, all patients were seropositive for measles specific IgM antibody.
