Study Details

Study Description

Brief Summary

The new coronavirus known as SARS-Cov-2 (severe acute respiratory syndrome -coronavirus 2) was first reported in December 2019 and rapidly became a public health emergency. The COVID-19 pandemic is now affecting sensitive regions with fragile health care systems, such as South America and Africa. Caregivers, in the front line of Covid19 patient management, may accidentally become infected and a source of infection during the incubation phase or in case of asymptomatic infection.

The objectives of this project are thus i) to assess SARS-Cov-2 spread over the hospital departments of Bamako by carrying out a systematic molecular screening of patients and caregivers, ii) to evaluate the feasibility of Point-Of-Care molecular assays in Mali and

  1. to estimate the immunity acquired from SARS-Cov-2 among health workers through serological testing, allowing also the assessment of asymptomatic caregiver rate and absence of re-infection among the immunized caregivers. Finally, iv) variability of the virus over time and spread of different variants around the world will be studied by sequencing the viral genome.

450 participants
Allocation:
Non-Randomized
Intervention Model:
Parallel Assignment
Intervention Model Description:
Interventions Serological screening of caregivers at D0, M1, M2, M3. Screening of patients by molecular biology: a nasopharyngeal swab will be performed to symptomatic hospitalized patients or who have been in close contact with a SARS-CoV-2 infected person without effective protective measures to search for SARS-CoV-2 genome. Positive clinical isolates will be sequenced. Screening of caregivers by molecular biology: a nasopharyngeal swab will be performed to symptomatic caregivers or who have seroconverted to SARS-CoV-2 or who have been in close contact with a SARS-CoV-2 infected person without effective protective measures to search for SARS-CoV-2 genome. Positive clinical isolates will be sequenced.Interventions Serological screening of caregivers at D0, M1, M2, M3.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Patients

- Hospitalized patients in one of the four centers in Bamako, with clinical signs of infection of the upper or lower respiratory tracts with fever or feeling of fever or any other signs of SARS-Cov-2 infection or who have been in close contact with a SARS-CoV-2 infected person without effective protective measures

Diagnostic Test: SARS-CoV-2 screening by molecular biology
SARS-CoV-2 RT-PCR in nasopharyngeal swab targeting 2 regions of the viral genome

Experimental: Caregivers

Caregivers of one of the four centers in Bamako. Serological screening: all. Molecular screening: with clinical signs of infection of the upper or lower respiratory tracts with fever or feeling of fever or any other signs of SARS-Cov-2 infection or who have seroconverted to SARS-CoV-2 or who have been in close contact with a SARS-CoV-2 infected person without effective protective measures

Diagnostic Test: SARS-CoV-2 screening by molecular biology
SARS-CoV-2 RT-PCR in nasopharyngeal swab targeting 2 regions of the viral genome

Diagnostic Test: Serological screening
Serological screening of caregivers at D0, M1, M2, M3 (anti-nucleocapsid antibodies).

Outcome Measures

Primary Outcome Measures

  1. Incidence rate of positive SARS-Cov-2 RT-PCR in Bamako hospital departments during the study [Through the completion of subject participation (up to 15 months after study start date).]

    Positive SARS-Cov-2 RT-PCRs are defined by the detection of SARS-Cov-2 genome after amplification using a test targeting 2 regions of the genome.

Secondary Outcome Measures

  1. Number of Cepheid Xpert® Xpress SARS-Cov-2 cartridges available for 19.8 USD/number required for the project [Through the completion of subject participation (up to 15 months after study start date).]

  2. Percentage of positive serological tests among the caregivers of the hospital departments of Bamako. [Assessed on the fourth serological assay performed (at Month 3).]

  3. Percentage of caregivers asymptomatic but immunized to SARS-CoV-2 [Assessed on the fourth serological assay performed (at Month 3).]

  4. Percentage of caregivers immunized and re-infected with SARS-CoV-2 [Through the completion of caregiver participation (up to 15 months after study start date).]

  5. Number of SARS-CoV-2 mutations/variants detected during the study [Through the completion of subject participation (up to 15 months after study start date).]

  6. Percentage of SARS-CoV-2 mutations/variants detected during the study [Through the completion of subject participation (up to 15 months after study start date).]
