Keywords
doxycycline, tigecycline, Orientia tsutsugamushi, scrub typhus
Brief summary
The goal of this randomized case-control study is to analysis of effectiveness of tigecycline in scrub typhus. The main question it aims to answer are: * \[question 1\]: Does tigecycline reduce fever faster than doxycycline in scrub typhus? * \[question 2\]: Is the use of tigecylcine tolerable in scrub typhus? Participants will assigned as doxycycline or tigecycline groups. Researchers will compare tigecycline group with doxycycline group, using defervescence time and adverse events.
Interventions
Doxycycline 100 mg orally every 12 hours for 7 days.
Tigecycline 100 mg intravenously as a loading dose, followed by 50 mg intravenously every 12 hours for 5 days.
