On average, symptoms showed up in the newly infected person about 5 days after contact. Rarely, symptoms appeared as soon as 2 days after exposure. Most people with symptoms had them by day 12. And most of the other ill people were sick by day 14. In rare cases, symptoms can show up after 14 days.

Rapid antigen tests (RATs) can detect COVID-19 even before you develop symptoms and can provide a result within 10 to 20 minutes. You can do the test at home or at the workplace and a medical professional is not required.
Risks to a patient of a false negative test result include: delayed or lack of supportive treatment, lack of monitoring of infected individuals and their household or other close contacts for symptoms resulting in increased risk of spread of COVID-19 within the community, or other unintended adverse events.
It is possible for this test to give a negative result that is incorrect (false negative) in some people with COVID- 19. This means that you could possibly still have COVID- 19 even though the test is negative. The amount of antigen in a sample may decrease the longer you have symptoms of infection.
