Criteria
Venezuelan haemorrhagic fever case definition
There are no current internationally accepted criteria or case definitions; however, a case definition has been proposed for Venezuelan haemorrhagic fever, which could be applied to all 5 diseases.[6] The proposed definition is as follows:
Suspect/probable case
Patient living in or in recent contact with rural areas within the endemic zone
Acute febrile illness characterised by most or all of: weakness, headache, myalgia, sore throat, vomiting and/or diarrhoea, haemorrhagic manifestations, leukopenia, thrombocytopenia.
Confirmed case
Above symptomatology
Laboratory confirmation of disease (e.g., via reverse transcriptase-polymerase chain reaction or serology).
