A 32-year-old California woman died just a day after she was diagnosed with the coronavirus, her family said in a new report.

Jessica Beatriz Cortéz, of Huntington Beach, southeast of Los Angeles, started to feel sick late last week, her family told the local Telemundo station.

“She began by complaining about body aches, that she felt a heaviness and fatigue,” her brother César Cortéz told the station, according to a translation by the Los Angeles Times.

Jessica, who immigrated from El Salvador to the US three years ago, showed up for work on Thursday, March 23, but soon afterward, her symptoms escalated to body pain and chills.

She was hospitalized on Friday, and died on Saturday, her brother said.

“This all happened in less than a week,” Cortez told the station. “I got a call that she was in very grave condition … I left what I was doing and went to the hospital and when I got there, she had already passed away.”

Cortez said it’s painful to think about how no one could be with Jessica when she died.

“That’s the hardest part,” he said. “That she died alone.”

Jessica’s family does not know if she had any pre-existing conditions.

She leaves behind a 9-year-old daughter.

Cortéz became the fourth Salvadoran immigrant to die of COVID-19 in the US, consular officials told the outlet. The three others died in New York.
