Following publication of the original article [1], we were notified that a few instances of “RT-PCR SARS-CoV-2 test” should actually read “SARS-CoV-2 test”. Methods (Abstract): Original text: “RT-PCR SARS-CoV-2 test”. Correction: This should read “SARS-CoV-2 test”. Methods (Main Text): Original text: “Individuals who had a positive RT-PCR SARS-CoV-2 test in August 2022, (…)”. Correction: This should read “Individuals who had a positive SARS-CoV-2 test in August 2022 (both PCR and rapid antigen test), (…)”. Current text: “1) names and contact numbers (landline or mobile) of a random sample of 10,000 individuals who had a RT-PCR SARS-CoV-2 test, (…)”. Correction: This should read “1) names and contact numbers (landline or mobile) of a random sample of 10,000 individuals who had a SARS-CoV-2 test, (…)”. The original article has been corrected.
