Table 1. Criteria used for selection of papers for the mapping of aetiology of non-malaria febrile illness in Southeast Asia.

Inclusion criteria	Study conducted in the Greater Mekong region (Cambodia, Laos, Vietnam, Thailand, Myanmar and the Yunnan Province of the People’s Republic of China).
	Study including patients (or a clear subset of patients).
	Patients tested by laboratory analysis (serology, molecular methods, culture or antigen tests) performed in a laboratory setting.
Exclusion criteria	No abstract or free full text access available.
	Editorial or opinion rather than publication of new data.
	Economic impact studies of febrile illnesses without pathological testing.
	Follow-up studies (cohort of patients already described in a previous study).
	Animal studies.
	Experimental (in vitro or in vivo cellular, molecular, biochemical studies or other studies that do not involve patients).
	Vaccine and drug trials.
	Modeling studies.
	Laboratory methods descriptions.
	Case reports and studies of biochemical or clinical outcomes only (e.g. liver function, pathology, disease features, clinical presentation of a disease).
	Biomarker evaluation.
	Travel (acute febrile illnesses associated with a travel episode, as place of infection may be in doubt).
	Other studies of disease not including identification of causes of fever (e.g. demographic surveillance, geographic information, vector transmission, climate impact).
