Brief Summary

Scrub typhus infection has been considered as seasonal and endemic infectious disorder with benign feature. However, the increasing mortality rate of scrub typhus has been recently reported in Southeast Asia and cause of death could be a fetal complicating cardiovascular disease. Therefore, the association and predictors for scrub typhus induced cardiovascular disease should be investigated to provide a timely and appropriate diagnosis and to reduce the mortality rate of complicated scrub typhus infection. Therefore, investigators prospectively investigate the association and predictors of cardiovascular disease in the participants with scrub typhus infection.
