An email sent to Panasonic employees Sunday says a Tesla employee working at the Gigafactory, east of Sparks, tested positive for COVID-19. The email says the employee was onsite at the Gigafactory for about an hour on March 21 before going home sick. There are no confirmed cases of the coronavirus on the Panasonic side of the Gigafactory. Last Thursday, Storey County manager Austin Osborne said that Tesla would be reducing its on-site staff by nearly 75 percent. Employees who had contact with the sick person have been sent home.
