  • Respiratory viruses were isolated from patients with acute respiratory infections in Busan during 2000-2001 and characterized for their antigenic properties. In 2000, 39 out of 43 isolated viruses were identified as influenza viruses and the others were adenoviruses. Among the isolated influenza viruses,23 were type A influenza viruses and 16 were type B influenza viruses. As a result of antigenic characterization, the influenza viruses were determined to A/Sydney/05/97(H3N2)-like, A/Beijing/262/95(H1N1)-like, and B/Harbin07/94-like viruses and serotypes of the isolated adenoviruses were type 1, 2, and 5. In 2001, 56 viruses were isolated and all of the viruses were identified as influenza viruses. They were A/panama/253/99(H3N2)-like and A/Newcaledonia/2007/99(H1Nl)-like viruses when determined by their antigenic properties. The sex distribution of the patients is as follows, 14 males (32.56%),23 females (67.44％) in 2000, and 23 males (41.07%), 33 females (58.93%) in 2001. Occurrence rate was found to be higher in female patients in both years. Age distribution of patients, in 2000, 48.84％ of infection occurred in 0 to 1 year old while in 2002, 33.93% occurred among 11-20 year olds. In 2000, occurrence rate was found to be high in January and again in April and various types of viruses were isolated. These results may be useful for vaccine development and establishment of reliable epidemic data.

  • Purpose: Cytomegalovirus (CMV) infection is mostly asymptomatic but can be detrimental to certain hosts. We investigated changes of CMV seroprevalence in Koreans before and after the year 2000. Methods: We reviewed laboratory values of patients who were tested for CMV immunoglobulin G (IgG) at Samsung Medical Center, Seoul, Korea, from January 1995 to December 2015. Changes in seroprevalence were analyzed by gender, age, region, and tested year period (period 1, 1995-2005 vs. period 2, 2006-2015). Results: Overall CMV seropositivity was 94.1% (10,900/11,584). There was no significant difference for CMV seropositivity among the two periods (94.2% vs. 94.1%) (P=0.862). CMV seropositivity in the 11 to 20-year age group in period 2 (78.8%) was significantly lower than that of period 1 (89.9%) (P=0.001). The seropositivity of individuals aged 31-40 years (97.4%) was significantly higher than that of younger age groups (P<0.001) and lower than that of older age groups (P<0.001). Of 2,441 females of reproductive age (from 15 to 49), CMV seropositivity was 97% (2,467/2,441). The seropositivity in women aged 20-24-years was higher than that of men in the same age group (97.6% vs. 85.6%, P=0.003). No significant difference was observed among different regions. Conclusions: Overall CMV seropositivity of Koreans was estimated to be 94% and the average seropositivity of reproductive women was 97%. Monitoring of the changes in seroprevalence including the reproductive age group is needed in the future.
