Sampling Method
Study Population
Any non-severely ill subject presenting with acute fever defined as: temperature of more than 38°C at initial evaluation of less than 7 days of symptoms at presentation.
For recruitment purposes, subjects will be classified into two groups:
- Children 2-17 years of age
- Adults 18-65 years of age
Description
Inclusion Criteria:
Any non-severely ill subject presenting with acute fever defined as: temperature of more than 38°C at initial evaluation of less than 7 days of symptoms at presentation.
Inclusion criteria:
- Children 2-17 years of age
- Adults 18-65 years of age
- Signed written informed consent for study participation. For recruitment purposes, subjects will be classified into two groups, children and adults. For children, age >2 years is the minimum cut-off, based on the amount of blood volume to be obtained in the study. WHO guidelines for allowable blood volume in 24 hours recommend that no more than 1-5% of total blood volume (75-80 ml/kg for older children) be obtained. Applying the average weight of a 2 year old toddler =12 kg, the allowable blood volume to be drawn in 24 hours at 1-5% of the total blood volume is 9.6 - 48 mL .
For minors, caregivers will provide informed consent. Documented assent for children of 12 to 16 years of age will be required for their participation.
Exclusion Criteria:
- Subjects who are felt to be in critical condition (based on clinician assessment or the presence of any general signs of critical illness as defined by WHO guidelines (for children: extensive vomiting, active seizure or recent history of seizures, altered mentation, inability to feed, or any of the severe IMNCI classifications; for adults: impending airway obstruction, central cyanosis, severe respiratory distress, feeble pulse, active seizure or recent history of seizures, or unconsciousness) because the target population for the study is non-severe febrile subjects.
- Subjects can only be enrolled once into the study.

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
Malawi febrile patients
Children and adults with fever presenting at the outpatient department
|
There is no intervention on the patients but biomarker assays are being evaluated for their performance to distinguish bacterial infection from non-bacterial infections in febrile patients
|
Brazil febrile patients
Children and adults with fever presenting at the outpatient department
|
There is no intervention on the patients but biomarker assays are being evaluated for their performance to distinguish bacterial infection from non-bacterial infections in febrile patients
|
Gabon febrile patients
Children with fever or with a recent history of fever presenting at the outpatient department
|
There is no intervention on the patients but biomarker assays are being evaluated for their performance to distinguish bacterial infection from non-bacterial infections in febrile patients

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Diagnostic sensitivity and specificity to determine bacterial infections compared to clinical and microbiological results aggregated in a study database.
Time Frame: 1year
|
Microbiological testing (blood culture positive/negative, malaria pos/neg, S. Tyhpi RDT pos/neg) and clinical assessments of symptoms (respiratory, gastro, no foci) will be recorded and reviewed by a clinical panel upon completion of the study to assign a final category (bacterial or non-bacterial).
These categories are used in the evaluation of the biomarker assays to evaluate their performance in differentiating bacterial from non-bacterial infections.
Where applicable, the same categories will be used to determine the area under the curve by employing receiver operator characteristics (ROC) analysis of quantitative markers.
