Primary Outcome Measures

Name	Time	Method
Amongst the 40 participants who convert to a positive PCR or or positive TGA-approved RAT for SARS-CoV-2, the proportion who received Ivermectin. To determine this, participants will be asked whether they took some/all of the study drug (for sensitivity analyses), Their information will be entered into the study database (REDCap) which will also contain their treatment allocation (only the study Pharmacists are unblinded to this information prior to database lock).[14 days after initial COVID-19 close contact]
