The man is 73-years-old and the woman is 57. They tested positive for the virus on Monday and have been placed in isolation, authorities say.

Also, one more person who was in close contact with the couple has been placed under observation.

Burkina Faso becomes the sixth sub-Saharan African country to report positive tests for coronavirus.
