On Thursday, the UK moved to the “delay” phase of its plan to tackle COVID-19.
As part of this phase, Mr Johnson said anyone with a “new, continuous” cough or fever is advised to self-isolate for seven days.
After seven days, if you feel better and no longer have a high temperature, you can return to your normal routine.
Coughing may persist for several weeks in some people, despite the coronavirus infection having cleared.
Jeremy Rossman, Honorary Senior Lecturer in Virology and President of Research-Aid Networks, University of Kent, said the Government’s strategy could be “effective”.
