What is Sennetsu Fever

Sennetsu Fever is a rare infectious disease caused by a bacterium called Ehrlichia sennetsu. It primarily affects individuals in certain regions of Southeast Asia, particularly Japan and Malaysia. The disease is transmitted to humans through the consumption of raw or undercooked fish, particularly freshwater fish.

Once infected, individuals may experience a range of symptoms including fever, fatigue, headache, muscle pain, and abdominal discomfort. These symptoms typically appear within 1-3 weeks after consuming contaminated fish. In some cases, individuals may also develop enlarged lymph nodes, liver inflammation, and skin rash.

Diagnosis of Sennetsu Fever is often challenging due to its similarity to other infectious diseases. Laboratory tests, such as blood tests, can help identify the presence of Ehrlichia sennetsu in the body. Treatment usually involves the administration of antibiotics, such as tetracycline or doxycycline, to eliminate the bacteria.

Prevention of Sennetsu Fever involves ensuring proper cooking of fish, especially freshwater varieties, to kill any potential bacteria. It is also important to maintain good hygiene practices and avoid consuming raw or undercooked fish in endemic areas.
