Step 1: Your friend must get tested
Your kitchen group friend must start self-isolating immediately and book a test.
Step 2: Self-isolation
If you're unvaccinated
If you're a close contact of a positive Covid-19 case, you're required to self-isolate for 10 days.
If you're fully vaccinated
If you're fully vaccinated and are identified as a close contact of someone with Covid-19 (whether Omicron or not), you're not required to self-isolate but should take an NHS rapid lateral flow test every day for 7 days to help slow the spread of Covid-1
'Fully vaccinated' means 14 days have passed since your final dose of a COVID-19 vaccine given by the NHS.
