Brief Summary
Plague is a deadly but highly treatable disease caused by the bacterium Y. pestis. Due to the historical development of Y. pestis as a bioweapon by several nation states, it is listed by the US as a potential bioweapon that could be used against US warfighters. Although this bacterium is ecologically established worldwide, it mostly affects impoverished people who live in rural low-resource areas of Madagascar. Plague is acquired directly from bites of infected fleas but, if left untreated, it can progress to the highly lethal pneumonic form that can result in human to human transmission. With the dangers of pneumonic plague in the context of both natural outbreak and as a bioweapon used against warfighter, the goal of this study is to investigate a diagnostic test that is able to rapidly and locally diagnose this disease in low-resource settings. This study aims to evaluate a US-developed new LFI (Lateral Flow Immunoassay) assay intended for capillary blood (finger-prick) to diagnose humans infected with Y. pestis. The investigators will rigorously validate with assay on human populations from active plague sites and correlate the results with the results of paired clinical samples used in standard medical workup using existing diagnostics tests.

Outcome Measures
Primary Outcomes (1)
LFI results on finger-prick blood correlate with the results of standard WHO-approved diagnostic tests for plague
Description: Standard WHO-approved diagnostic testing uses bubo aspirates or sputum as clinical matrices to perform the following tests: F1RDT, qPCR analysis, and culture. WHO defines a confirmatory positive plague case when the bubo or sputum is positive on F1RDT and positive on either qPCR or culture.
Up to 3 weeks post sample collection and processing of each participant.
Secondary Outcomes (1)
LFI results on finger-prick blood correlate with LFI results from bubo aspirate or sputum clinical matrices.
Up to 3 weeks post sample collection and processing of each participant.
Other Outcomes (1)
LFI results on finger-prick blood correlate with the test results on venous blood using the following diagnostic methods: LFI, qPCR, ELISA and FilmArray Warrior Panel.
Two years through sample collection and analysis completion from 05/2020 to 05/2022.
Study Arms (2)
Malagasy Participants
Malagasy Participants. Subjects will be recruited at rural health centers throughout Madagascar. Participants will be comprised of rural people with symptoms consistent with plague. The Madagascar Ministry of Public Health requires declaration of all suspected human plague cases and collection of biological samples (sputum and/or bubo aspirates) from these cases for medical workup for confirmation.
USN Health Research Center
USN Health Center Participants. The subject population will consist of active duty US Naval personnel and DoD beneficiaries presenting to participating study sites in the United States with influenza-like symptoms (fever, cough, sore throat). Since the US is non-endemic for plague, all participants will be presumed to be negative for Y. pestis.
Interventions
A dipstick type of rapid test for antigens of the plague bacterium Yersinia pestis in samples from enrolled participants from both a known geography of plague activity (Madagascar) as well as samples from a geographically separated population of likely plague free status (US Naval Health Research Center, San Diego, CA).
Eligibility Criteria
Malagasy Participants. Subjects will be recruited at rural health centers throughout Madagascar. Participants will be comprised of rural people with symptoms consistent with plague. The Madagascar Ministry of Public Health requires declaration of all suspected human plague cases and collection of biological samples (sputum and/or bubo aspirates) from these cases for medical workup for confirmation. USN Health Center Participants. The subject population will consist of active duty US Naval personnel and DoD beneficiaries presenting to participating study sites in the United States with influenza-like symptoms (fever, cough, sore throat). Since the US is non-endemic for plague, all participants will be presumed to be negative for Y. pestis.
You may qualify if:
- Adults 18 to 75 years old (male and female): Able to receive and give verbal communication.
- Children 5 to 17 years old (vulnerable population): Parents or legal guardian must be available to give permission. Parents or legal guardian to consent for children (5-6 years).
