1. National headline figures
Positive cases referred to the contact tracing system between 21 and 27 June 2020
452 positive cases were referred to the contact tracing system. 334 cases were eligible for follow-up by local contact tracing teams. 118 cases were not eligible for follow-up by local contact tracing teams. The majority of these are cases that occurred in closed settings such as hospitals, care homes and prisons. These cases are escalated to regional teams for onward management.
Of the 334 positive cases that were eligible for follow-up, 270 (81%) were reached and asked to provide details of their recent contacts.
Close contacts identified between 21 and 27 June 2020
659 people were identified as close contacts. 620 close contacts were eligible for follow-up by local contact tracing teams. 39 close contacts were not eligible for follow-up by local contact tracing teams.
Of the 620 close contacts that were eligible for follow-up, 518 (84%) were successfully contacted and advised accordingly, or had their case otherwise resolved.
These figures relate to all close contacts identified between 21 and 27 June. Some may have been identified by positive cases referred to the contact tracing system prior to 21 June. The figures may also include some close contacts eligible for follow-up by local contact tracing teams that were identified by positive cases escalated to regional teams for onward management. Resolved cases cover a small number of instances where the same contact is identified by multiple positive cases concurrently. On these occasions, contact tracing teams will work from a single record relating to that contact and mark the additional records as resolved.
2. Data for 1 to 21 June 2020
Early reporting, covering the first three weeks of contact tracing in Wales, was based on data reported by local and regional contact tracing teams prior to the introduction of the national digital system.
In Wales, during the period from 1 to 21 June, 1,905 positive cases were referred to local and regional contact tracing teams. This resulted in 2,616 contacts identified for follow-up, of which 2,117 have been successfully contacted and advised accordingly.
There will be a small amount of overlap in the reporting from the national digital system and the early reporting provided by local and regional contact tracing teams. For this reasons we would not recommend combining figures from the two different reporting streams. Cumulative reporting in future versions of this release will focus on data from 21 June 2020.
3. Quality and methodology information
This data is management information provided to the Welsh Government by the NHS Wales Informatics Service. We are publishing this to provide a weekly summary of contact tracing activity in Wales during the coronavirus (COVID-19) pandemic. This data has not undergone the same level of quality assurance as official statistics and the data may be subject to future revisions.
Data has been extracted from the national digital contact tracing system during an early stage of its implementation. Some activity is not currently recorded consistently across different regions and therefore will not be captured in the figures presented here. We will continue to review the presentation and coverage of the data presented in this release as data quality improves.
Data included in this release was extracted from the contact tracing system at 17:45 on 1 July 2020. This extract was taken 4 days after the end of the reporting period in order to capture follow-up activity relating to cases referred towards the end of the reporting period.
It may not be possible to trace all individuals referred to the contact tracing service. For various reasons contact details will not have been provided for some individuals and others may not have responded to calls, texts or emails from tracing teams.
The number of cases referred for contact tracing is different to the number of new cases published by Public Health Wales due to differences in timing and the level of validation carried out. Raw data from the laboratory testing system is fed into the contact tracing system that can, for example, include previously identified positive cases. Public Health Wales provides data for surveillance purposes and uses data from a fixed time cycle for consistency of reporting and also validates the data to remove previously identified cases. We are carrying out further work to understand and explain these differences.
National Statistics status
These statistics are not National Statistics. However, as far as has been practicable, they have been collected and validated in accordance with the pillars and principles within the Code of Practice for Statistics. We continue to develop the data collection and quality assurance process to improve the data.
These statistics have been produced quickly in response to developing world events.
Well-being of Future Generations Act (WFG)
The Well-being of Future Generations Act 2015 is about improving the social, economic, environmental and cultural wellbeing of Wales. The Act puts in place seven well-being goals for Wales. These are for a more equal, prosperous, resilient, healthier and globally responsible Wales, with cohesive communities and a vibrant culture and thriving Welsh language. Under section (10)(1) of the Act, the Welsh Ministers must (a) publish indicators ('national indicators') that must be applied for the purpose of measuring progress towards the achievement of the wellbeing goals, and (b) lay a copy of the national indicators before the National Assembly. The 46 national indicators were laid in March 2016.
Information on the indicators, along with narratives for each of the well-being goals and associated technical information is available in the Well-being of Wales report.

The statistics included in this release could also provide supporting narrative to the national indicators and be used by public services boards in relation to their local well-being assessments and local wellbeing plans.
This is currently a weekly statistical release. It will be published at 9:30am every Thursday. We will review the frequency in line with changing user need.
The next release will be on Thursday 9 July.
