After an incubation period of 3–15 days (usually 5 to 8), classical DF begins with an abrupt onset of high fever. During the febrile phase, dehydration may cause neurological disturbances and febrile seizures in young children (6). The condition is self-limiting through debilitating illness with headache, retro-orbital pain, myalgia, arthralgia, petechiae rash, and leucopenia. A macular-papular recovery rash appears 3–5 days after the onset of fever, and it usually starts on the trunk before spreading peripherally (7). DF is sometimes referred to as ‘break bone fever’ due to its incapacitating symptoms with severe muscle and joint pain (8); or ‘seven-day fever’ since the symptoms usually persist for 7 days.
