Management
Infected individuals should seek medical attention for management. The infection can be effectively treated by antibiotics. Symptomatic treatment such as fluid replacement and adequate rest is also important. Strict personal hygiene should be observed in order to prevent transmission of bacteria to the others. The majority of patients can fully recover after treatment. However, about 2 to 5% of patients will become carriers of the bacteria and they may require long-term follow-up.
