Brief Summary

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the resulting COVID-19 pandemic present important diagnostic challenges. Point-of-care tests that detect SARS-CoV-2 antigen have the potential to allow earlier detection and isolation of confirmed cases compared to PCR-based diagnostic methods, and could be implemented at Ports of Entry (PoE) to screen low-prevalence populations effectively.This study will assess the performance of available antigen Ag-RDTs such as the Panbio and Standard Q SARS-CoV-2 rapid antigen tests. Approximately 15,000 subjects entering Botswana at Ports of Entry will be enrolled over a 6-months period or more. SARS-CoV-2 RT-PCR will be used as a reference standard. A subset of participants will also be contacted, re-evaluated and re-tested at 48-72 hours following initial assessment, to assess for the impact of incubating infection on the performance of the Ag-RDTs. In order to assess the impact of viral genetic variability on test performance, genomic sequencing will be part of the study. All SARS-CoV-2 PCR positive samples will undergo genomic sequencing to determine the virus lineages or variants. In addition to assessing the performance of each of the Ag-RDTs, a set of testingalgorithms that could be implemented at Ports of Entry, including the sequential use of multiple Ag-RDTs with or without RT-PCR confirmation, will be assessed.

Sampling MethodNon-Probability Sample
Study Population

Study participants will be enrolled at PoE at study sites within the Greater Gaborone Health District. 1. Sir Seretse Khama International Airport 2. Tlokweng, Ramotswa, Pioneer and Ramatlabana land borders Participants will be included regardless of symptoms. Individuals younger than 18 years of age or unable to provide informed consent will be excluded from the study. A subset of study subjects are expected to show evidence of negative SARS-CoV-2 RT-PCR testing within the 72 hours prior to study enrolment. These subjects will be eligible for the study; however, based on the sample size considerations described above, the number of subjects with documented negative RT-PCR testing will be capped at 1,000.

You may qualify if:

  • In order to meet the study objectives, study recruitment will focus on the population meeting the following eligibility criteria:
  • Age ≥ 18 years crossing ports of entry in Greater Gaborone Health District \[including International Airport, Ports within Gaborone Health Districts ((as above)
  • Able to understand the scope of the study and provided written informed consent

You may not qualify if:

  • Participants who are less than 18 years or who are unable to provide informed consent.
  • Any contraindications to nasopharyngeal sample collection: recent nasal trauma or surgery, markedly deviated nasal septum, or a history of chronically blocked nasal passages or severe coagulopathy
  • Vulnerable populations as deemed inappropriate for study by site PI
