The Epidemiology and Confirmation of Diagnosis of Scrub Typhus in Prachuap Khiri Khan Province
The survey was carried out to evaluate the situation and prevalence of scrub typhus case by comparing between clinical diagnosis and laboratory confirmation and the infection rate of reservoir animals and type of vector. The study selected 100 cases from the patients undergoing clinical diagnosis in...
