Also called Undifferentiated fever
A person presenting with a body temperature of ≥38°C/ 100.4°F (or recent history of fever) without an obvious diagnosis or focus of infection. A person may also have headache, retro-orbital pain, myalgia, arthralgia, nausea or vomiting but without any symptoms fitting another syndromic definition.
Conditions from presumed viral infection should be included in surveillance. If no thermometer is available, a patient who was or complained of being ‘hot to touch’ may be considered to have a fever. These conditions for fever should also be applied to the other fever syndromes below.
No definitive time period is given for recent history of fever. This is left to the discretion of the clinician, who will take into account the disease(s) being queried.
