Conditions
Brief summary
Participants who meet the eligibility criteria and who consent to participation or whose parents/legal guardian consent to their participation, will be enrolled in the study for a period of up to 14 days. Enrolment visit (Day 1) assessments for all participants will include the collection of throat swabs, testing by staff at the site using the ellume·lab Group A Strep Test and testing for Group A Streptococcus by a central laboratory using bacterial culture and polymerase chain reaction (PCR). All participants will be followed up with a phone assessment of adverse events between Days 2-14.
