A large number of viruses belonging to Genus Hantavirus in Family Bunyaviridae are etiologic agents for hemorrhagic fever with renal syndrome (HFRS), or hantavirus pulmonary syndrome (HPS). Hantaan (HTN), Seoul (SED), Belgrade (BEL), Puumala (PUU) serotype viruses are well known causative agents for HFRS in Eurasian continent. Among those viruses Hantaan and Seoul serotypes are well known to cause HFRS in Korea, but there are some sporadic incidence by other than Hantaan or Seoul viruses. Recently we have developed the combined Hantaan-Puumala virus vaccine to prevent world-wide occuring HFRS. This combined vaccine is formalin inactivated, suckling mouse and suckling hamster brain extracts for Hantaan and Puumala viruses, respectively. Protein contents of this purified candidate vaccine is $27\;{\mu}g/ml$, which contains 1,024 ELISA antigen units to each virus, but content of myelin basic protein which is causing experimental allergic encephalomyelitis is less than 0.1 ng/ml. Thirty hamsters were given twice at one month interval intra-muscularly and bled on 30 days after each vaccination from retro-orbital sinus vein. Antibody titers were tested against 5 major serotype viruses, Hantaan, Seoul, Belgrade, Puumala and Sin Nombre viruses by IFA and PRNT. The mean IF antibody titers on 30 days after primary shot were 78.4, 68.8, 68.8, 37.9, and 15.6; mean neutralizing antibody titers were 65.4, 12, 6.1, 65.6 and 0.5 against Hantaan, Seoul, Belgrade, Puumala and Sin Nombre viruses, respectively. The mean IF antibody titers on 30 days after booster shot were 686.9, 567.5, 550.4, 516.3, and 430.9; and neutralizing antibody titers were 710.8, 41.9, 24.3, 409.9, and 1.6 against Hantaan, Seoul, Belgrade, Puumala and Sin Nombre viruses, respectively.

HRccine was administered subcutaneously for 4 weeks to rabbits at dose levels of 300, 60 and 12 times the expected clinical dose to evaluate the subacute toxicity. There were no effects in clinical signs, body weight changes, food consumption, water consumption, urinalysis and blood biochemistry in any animals tested. In hematological examinations, decrease of lymphocyte counts and increase of platelet counts were observed in the medium- and high-dose treated groups. Absolute weights of thymus were tending to decrease, but no pathological changes were observed in microscopic examinations. The no-effect dose in subacute toxicity study of rabbits was considered to be 300 times the expected clinical dose.

HRccine was administered subcutaneously to rats for 4 weeks at dose levels of 300, 60 and 12 times the expected clinical dose to evaluate the subacute toxicity. There were no treatment-related effects in clinical signs, body weight changes, food consumption, water consumption, urinalysis and blood biochemistry in any dose groups. In hematological examinations, increase of leucocyte counts and decrease of hemoglobin concentration were observed in the high dose-treated group. However, no treatment-attributable pathological changes were observed in microscopic examinations. The no-effect dose in subacute toxicity study of rats was considered to be 300 times the expected clinical dose.

For easy and rapid screening of hemorrhagic fever with renal syndrome (HFRS) without any laboratory equipment, dot blot enzyme immunoassay was developed and tried to detect anti-hantavirus antibodies. The nucleocapsid protein of Hantaan virus was isolated by affinity chromatography and used for making the dot strip. 28 of 29 Hantaan virus infected sera showed positive signals and 21 of 22 HFRS negative sera showed no positive signals. Anti-Seoul virus monoclonal antibody also exibited positive signal but the intensity of colorization was approximately 5 fold less than that of anti-Hantaan monoclonal antibody. The sensitivity of dot blot assay was equal or superior to indirect immunofluorescent assay (IFA) or ELISA test. Overall, the screening results with dot blot assay showed 92.2 % of concordance with IFA or ELISA test. This results suggests that dot blot assay could be applied a tool for easy and rapid screening of HFRS.

Objectives: Infectious diseases are known to be affected by climate change. We investigated if the infectious diseases were related to meteorological factors in Korea. Methods: Scrub typhus, hemorrhagic fever with renal syndrome (HFRS), leptospirosis, malaria and Vibrio vulnificus sepsis among the National Notifiable Infectious Diseases were selected as the climate change-related infectious diseases. Temperature, relative humidity and precipitation were used as meteorological factors. The study period was from 2001 through 2008. We examined the seasonality of the diseases and those correlations with meteorological factors. We also analyzed the correlations between the incidences of the diseases during the outbreak periods and monthly meteorological factors in the hyper-endemic regions. Results: All of the investigated diseases showed strong seasonality; malaria and V. vulnificus sepsis were prevalent in summer and scrub typhus, HFRS and leptospirosis were prevalent in the autumn. There were significant correlations between the monthly numbers of cases and all the meteorological factors for malaria and V. vulnificus sepsis, but there were no correlation for the other diseases. However, the incidence of scrub typhus in hyper-endemic region during the outbreak period was positively correlated with temperature and humidity during the summer. The incidences of HFRS and leptospirosis had positive correlations with precipitation in November and temperature and humidity in February, respectively. V. vulnificus sepsis showed positive correlations with precipitation in April/May/July. Conclusions: In Korea, the incidences of the infectious diseases were correlated with meteorological factors, and this implies that the incidences could be influenced by climate change.

Hantaviruses are found worldwide and are known to cause two serious and often fatal human disease: hemorrhagic fever with renal syndrome(HFRS) and hantavirus pulmonary syndrome(HPS). The typical clinical prodrome consists of fever, chills, myalgia, headache, and gastrointestinal symptoms. Treatment usually involves maintenance of fluids, blood pressure, ventilation and electrolytes. We report a patient who had multisystem inflammatory symptom with Hantaan virus antibody positive accompanied by mild fever and myalgia. This case was diagnosed as HFRS. This patient was treated by Galgun hegi-tang. As a result of this treatment, symptoms were markedly improved.

Although many pharmaceutically useful proteins are produced in E. coli expression system, it is very are rare for the system to be used in the production of diagnostic antigen due to a major problem, i.e., false-positive reaction of e. coli host-derived proteins contaminating purified diagnostic antigen with human sera. The N (nucleocapsid) protein of Seoul virus causing haemorrhagic fever with renal syndrome (HFRS) was produced in E. coli BL21 (DE3), and used for the detection of N protein-specific antibodies in human sera. Using the N protein as a diagnostic antigen of HFRS, the false-positive reaction was cleared by merely mixing the test sera with the extract of E. coli host strain not harboring expression plasmid.

Hantavirus is a genus of the Bunyaviridae family consisting following serotype groups: Hantaan, Seoul, Puumala, Prospect Hill, Thailand, Belgrade, Thotta palayam, Sin Nombre. Most of Hantavirus group have been associated with many clinically similar disease known collectively as hemorrhagic fever with renal syndrome (HFRS). Hantaan virus is the prototype of the genus hantavirus, originally isolated from Apodemus agrarius. Bat was found as a natural host for Hantaan virus in Lee's lab for the first time. Then, Hantaan-like virus was isolated Hantaan-like virus from bat. To identify hantaviruses that are present in Korea among bats, bats were collected from Jeong-Sun, Won-Joo, Chung-Ju and Hwa-Cheon area, RNA was isolated from lung and serum. RT-PCR was performed with a universal primer from M segment. Nested RT-PCR was carried out to differentiate Hantaan, Seoul and Puumala virus using serotype specific primers. As we expected, Hantaan viruses were detected in bats and Seoul virus was not detected. Interestingly, Puumala viruses were also detected in bats from Won-Ju, but not in other areas. Puumala virus is originally isolated from Clethrinomys glareolus, and cause light HFRS. Recently, Paradoxomis webbiana, a wild bird turn out to be a reservoir for Puumala virus in Korea. These data indicate that bat is a new natural reservoir of Puumala virus.
