COVID-19 14-day epidemiology reports - November 2021

COVID-19 14-day epidemiology reports - November 2021 -

A technical issue impacted processing on CIDR on 2/11/2021 resulting in an artificially low number of notifications reported on CIDR on the 2/11/2021 and an artificially high number on subsequent days. The bulk of the backlog from 2/11/2021 was processed on CIDR on 3/11/2021.

Notwithstanding the technical issue experience on the 2/11/2021, the number of notifications on CIDR will differ from other HSE data sources, such as positive SARS CoV-2 results uploaded to the COVID Care Tracker, for several reasons including:

• Deduplication of repeat positive tests in the same person
• Differing upload schedules by the laboratories to CCT and CIDR – uploading of positive records on CIDR by laboratories is a more manual process than uploading to CCT. Uploading to CIDR typically occurs on the day or within one day of authorisation of the laboratory test result.
• The time required for the two-step method of processing notifications on CIDR - this typically occurs either on the day or within one day of laboratories uploading positive records on CIDR.

Typically, the daily number of notifications to CIDR lag approximately one day behind the number of positive SARS CoV-2 results uploaded to the COVID Care Tracker. However, changes in the timeliness of the processing steps described above can increase or decrease this lag.

CIDR as the national surveillance system is the definitive source for validated data on COVID-19 cases in Ireland which meet Irish and European case definitions.
