• INFECTED COHORT -- ADULTS WITH SUSPECTED SARS-COV-2 INFECTION --
• An adult qualifies as having suspected SARS-CoV-2 infection if meeting criteria a, b or c below:
• Patients who meet the following clinical criteria plus one of the epidemiological criteria:
  • Clinical Criteria: Acute onset of fever and cough OR acute onset of any three of more of the following signs or symptoms: fever, cough, general weakness /fatigue, headache, myalgia, sore throat, coryza, dyspnea, anorexia/nausea/vomiting, diarrhea, altered mental status.
  • Epidemiological Criteria:
  • Residing or working in an area with a high risk of transmission of virus: closed residential settings, humanitarian settings such as camp and camp-like settings for displaced persons; anytime within the 14 days before symptom onset; or
  • Residing or travel to an area with community transmission anytime within the 14 days before symptom onset; or
  • Working in any health care setting, including within health facilities or within the community; anytime within the 14 days before symptom onset.
• A patient with severe acute respiratory illness: (acute respiratory infection with history of fever or measured fever of ≥38C°; and cough; with onset within the last 10 days; and requires hospitalization).
• An asymptomatic person not meeting epidemiologic criteria with a positive SARS-CoV-2 Antigen-RDT.
  • ADULTS WITH PROBABLE SARS-COV-2 INFECTION --
  • An adult qualifies as having probable SARS-CoV-2 infection if meeting any one of a-d below:
• A patient who meets clinical criteria for suspected SARS-CoV-2 AND is a contact of a probable or confirmed case or linked to a COVID-19 cluster;
• A suspect case with chest imaging showing findings suggestive of COVID-19 disease;
• A person with recent onset of anosmia (loss of smell) or ageusia (loss of taste) in the absence of any other identified cause;
• Death, not otherwise explained, in an adult with respiratory distress preceding death AND was a contact of a probable or confirmed case or linked to a COVID-19 cluster
  • ADULTS WITH CONFIRMED SARS-COV-2 INFECTION --
  • An adult qualifies as having confirmed SARS-CoV-2 infection if meeting any one of a-d below:
• Any person with a positive Nucleic Acid Amplification Test (NAAT);
• Any person with a positive SARS-CoV-2 Antigen-RDT OR positive SARS-CoV-2 antibody test\* AND meeting either the probable case definition or suspect criteria A OR B;
• An asymptomatic person with a positive SARS-CoV-2 Antigen-RDT who is a contact of a probable or confirmed case
• Any person with a positive SARS-CoV-2 nucleocapsid protein antibody test OR a positive SARS-CoV-2 spike protein antibody test IF not vaccinated
  • (\*)This protocol modifies the WHO criterion b to add detectable SARS-CoV-2 antibody as a qualifying test.
  • UNINFECTED COHORT -- ADULTS WITH NO SARS-COV-2 INFECTION --
• Does not meet WHO criteria for a suspected, probable, or confirmed case of SARS-CoV-2 infection, AND
• Has a documented negative SARS-CoV-2 PCR test from a respiratory specimen in the past, if being enrolled as a post-acute control (see XII.H), AND
• Has a documented negative SARS-CoV-2 PCR test from a respiratory specimen at the time of enrollment/screening, AND
• Has a negative SARS-CoV-2 nucleocapsid protein antibody and spike protein antibody test (spike only if not vaccinated) at the time of enrollment, AND
• Live in the same communities or recruited from the same sources as those in the SARS-CoV-2 infected cohort, AND
• Note: uninfected individuals may participate independent of their vaccination status
