It's the process for testing people who have coronavirus symptoms and tracing people they have been in close contact with, so that they can get a test and self-isolate if they test positive.
Joined Up Care Derbyshire have more about how test and trace works. If you have coronavirus symptoms then you need to book a test and start isolating immediately, together with all other members of your household.
If English is not your first language, there is information in some other languages attached to this page and you may also find information translated by the Doctors of the World organisation helpful.
There are British Sign Language videos available about the test and trace alert system, how you can play your part and information about symptoms.
If you think you or someone in your household might have coronavirus, the government has more information and stay at home guidance. This information is available in several languages.
Test and trace information for parents and carers
Anyone who develops symptoms, whatever their age, can get a test.
Book a test within 5 days of experiencing a high temperature, a new, continuous cough or loss or change to sense of smell or taste.
The test involves taking a swab of the nose and throat. Children aged 12 or over can use the swab themselves or can have help. Children aged 11 or under will need a parent or carer to do it for them.
If you or someone in your household tests positive for coronavirus you'll be contacted by the NHS Track and Trace team. You'll be asked where you have visited and who you've been in contact with. It's important that you give the correct information to keep everyone safe.
Your close contacts will be asked to self-isolate at home to stop the spread of the virus. If you're traced as a close contact you must stay at home.
We're all in this together. By doing the right thing you are helping to protect your friends and family and things can get back to normal more quickly.
What test and trace means for businesses
If you run a business or lead a place of worship, find out what you need to do if you're informed of a confirmed case of coronavirus by NHS Test and Trace, an employee, customer or your local Public Health England Health Protection Team.
Simple measures like regular hand washing, wearing face coverings in enclosed public spaces, and social distancing are still the best way to prevent the spread of coronavirus.
What we're doing to help
We're leading the work taking place in Derbyshire to prepare for potential outbreaks of coronavirus in the county and helping to contain any outbreaks as part of the test and trace programme.
Our COVID-19 Outbreak Management Plan sets out our approach which involves working with partners to protect local residents by preventing, managing and eliminating the virus over time.
This work includes monitoring data sent to us on a weekly basis from Public Health England about the number of new cases in Derbyshire.
Managing the coronavirus involves working with partner organisations at every level from the government and the NHS through to our local district and borough councils, and of course, the people who live and work in Derbyshire.
We have a range of useful advice and guidance for businesses.
