Derryk Ramirez-Lopez had faced a series of medical ailments before he was set to begin the first grade this year in Omaha, according to the Omaha World-Herald.

Phil Rooney, a spokesman for the Douglas County Health Department, said until there's a death certificate, health officials couldn't confirm the cause of death.

Douglas County -- the state's most populous county -- has reported 10,593 total confirmed cases of COVID-19. About 1,300 of those infections were people 19 years old or younger, the Omaha World-Herald reported.

Meanwhile, Nebraska recorded just under 1,000 coronavirus cases back on April 15, according to the Nebraska Department of Health and Human Services.
