Tsutsugamushi disease(scrub typhus), the major cause of febrile illness in Korea, is caused by Rickettsia tsutsugamushi. Since several U.N. army patients of tsutsugamushi disease in Korea were first reported in 1951, the case had not been reported for more than 30 years until 1985. The first Korean tsutsugamushi patients were recognized in 1986 and the disease has been found to be prevalent in all areas of Korea. R. tsutsugamushi was also isolated in Korean residents in 1987. Thereafter, tsutsugamushi disease has been shown to be widely spread throughout the country.
Especially, the seropositive rate to R. tsutsugamushi among the patients with acute febrile episodes during October through November were 40-50%.
To understand the sero-epidemiological patterns of scrub typhus in Chollanam-do, 131 patients sera with acute febrile episodes from 24 local health centers were tested for the antibody to R. tsutsugamushi by indirect immunofluorescent antibody technique from January to December in 1995.
Out of 131 patients, 95(72.5%) patients showed positive reaction to R. tsutsugamushi and the male outnumbered the female slightly. 37.9% of seropositives to R. tsutsugamushi was in the age of the sixties and between the forties and sixties of the age were 82.1%. Among 24 local health center, 23 showed positive reaction to R. tsutsugamushi.
Scrub typhus was the most prevalent in October and November, showing 87.2% of total.
These results might provide the basic information for the management of scrub typhus in Chollanam-do, where the epidemiological studies on scrub typhus was not carried out enough.
