The superintendent of the Papillion La Vista Community Schools tested positive for COVID-19 last week, a school official said.
Andy Rikli was experiencing mild symptoms as of Saturday, according to district spokeswoman Annette Eyman.
Rikli will be in isolation through Thursday and would be able to return Friday, Eyman said.
In a memo to his staff, Rikli wrote that he started to experience symptoms Monday evening. He said he stayed home from work Tuesday and was tested through TestNebraska. He said he did not get results back immediately, so he stayed home again Wednesday.
He then had a rapid test conducted that came back negative. But then he received a positive result from TestNebraska.
Eyman said Rikli does not know how he contracted the disease.
The school district has a mask requirement for students and staff.
