If you are a household member of a key worker, you should continue to self-isolate until your temperature is normal and you feel better. If you become unwell again, you should self-isolate again, and may need a further test.
If you have had a NEGATIVE test result but have never had any symptoms, there is no need to self-isolate. If you subsequently become unwell, you should self-isolate, and may need a further test.
The key worker in your household may return to work, but if they (the key worker) then develop symptoms, they must self-isolate immediately, and contact their designated testing centre to be assessed for a test themselves.
The key worker’s employing organisation, who arranged your test, must be informed that you have your test result. The key worker should liaise with their employer regarding sick leave and return to work, based on the result of your test and their own health status. This may include an occupational health assessment.
