Obi said in a statement in Enugu that the case happened to be another contact of the third case reported in the state capital who had positive travel history from outside the state.
This brings the total number of cases ever reported in Enugu to 10 with eight active cases.
The commissioner said the patient had also been admitted for isolation and treatment.
He appealed to the residents to stay at home and only go out when absolutely necessary.
According to him, if you must go out, wear a mask, practice physical/social distancing, exercise proper respiratory hygiene.
“Wash your hands as often as possible with soap and running water for at least 20 seconds or use an alcohol-based hand sanitizer when there is no facility to wash your hands
“Sanitize surfaces all around you as often as possible with a 1in6 mixture of bleach and water
“If I do these, I protect you, if you do these you protect me!” Obi said.
