COVID-19 Surveillance Reports
From Sunday 19 April the Department of Health will be releasing the daily statistics on coronavirus (COVID-19) which will be available at www.health-ni.gov.uk
The daily update from the Department of Health replaces the Daily Bulletin published by the PHA up to 19 April 2020.
COVID-19 is a new illness that can affect your lungs and airways. It's caused by a type of virus called Sars-CoV-2 (coronavirus).
The Public Health Agency Health Protection surveillance team has established surveillance systems which are used to monitor COVID-19 activity in Northern Ireland. The systems allow us to monitor trends, inform public health measures to reduce COVID-19 transmission, and to measure the impact of public health measures to reduce COVID-19 transmission in both hospital and community settings.
As this is an emerging pandemic the systems used will constantly evolve and the complexity of the analysis will increase. All updates will be documented here.
The current surveillance systems include:
1. Virology laboratory reports of COVID-19 test results
Currently, COVID-19 testing is performed in patients who:
- have clinical evidence of COVID-19 Disease (clinical or radiological evidence of pneumonia OR acute respiratory distress syndrome OR influenza like illness)
