Prolongations of PT and PTT were significantly higher in dengue fever (DF) 90% and 76.2% than dengue hemorrhagic fever (DHF) 10% and 23.8% patients respectively. Clinical manifestations include hepatic dysfunction, renal failure, coagulopathy, and shock. They may range from subclinical infection to dengue fever, dengue hemorrhagic fever (DHF), and eventually dengue shock syndrome (DSS). The initial, and currently only, outbreak of Lujo virus in September–October 2008 left 4/5 patients dead. Once affected persons acquire long-life serotype specific immunity. The initial phase of DHF is similar to that of dengue fever and other febrile viral illnesses.
