Murine typhus: a forgotten cause of febrile illness in Singapore.

We report 6 cases of marine typhus presented to us within a period of 3 months. The diagnoses were made based on the Weil-Felix reaction in the context of supportive clinical and epidemiological features, and response to appropriate antimicrobial therapy. This review serves to remind us that murine typhus is still an important cause of acute febrile illness in Singapore, especially among the migrant Indian workers.
