If You Think You Have COVID Make Sure To Isolate for 10-Day – According to Latest UK Scientific Evidence

Posted on 30 July 2020

  • The self-isolation period for those who have or suspect that they have COVID-19 has been extended to 10 days
  • Evidence suggests even those with mild symptoms remain infectious for 7 – 9 days after illness onset
  • A new, continuous cough, fever and/or loss of smell or taste should be acted upon by self-isolating and seeking a test.

Starting today (30th of July) the self-isolation period has been extended to 10 days for those who have coronavirus (COVID-19) symptoms or a positive test result.

This decision was made in an attempt to avoid a resurgence of the virus in the UK, in light of new evidence that people with mild to moderate symptoms may continue to be infectious for longer than was originally thought.

Evidence, although still limited, has strengthened and shows that people with COVID-19 who are mildly ill and are recovering have a low but real possibility of infectiousness between 7 and 9 days after illness onset.
