The measure by Sierra Leone is the most extensive by any country since the Ebola current outbreak started.

People were reported to have poured into the streets of Freetown just before the official end of the lockdown to celebrate.

According to the head of Sierra Leone’s Emergency Operations Centre Stephen Gaojia, who spoke with the BBC, the exercise was largely successful, and the compliance and receptiveness of Sierra Leoneans was “overwhelming”.

“We were able to discover quite a lot of people who have been infected… the numbers are not available as of today but I can assure you that we already have a little over 150 people who willingly reported to the nearest holding or isolation centre to be tested,” he said.
