A nurse who was working on the frontlines of the coronavirus pandemic has died from COVID-19 complications at the age of 51.

Sally Fontanilla died on Monday after spending two months on a ventilator in the intensive care unit, her family confirmed on a GoFundMe set up in her honor.

A description on the page described Fontanilla as a nurse of 23 years who was "risking her life for the lives of others."

Fontanilla was working in the COVID-19 unit at St. Mary Medical Center in Apple Valley, California, when she fell ill, CBS Los Angeles reported.

Her husband Ben, who also works at the same hospital, told the outlet that the family was concerned for Fontanilla at the start of the COVID-19 outbreak due to her preexisting medical conditions — which included asthma and diabetes — and the nurse took several months off to protect herself.

Fontanilla's husband said she returned to work at the hospital in the summer when she thought her risk of contracting the novel coronavirus would be lower.

"We take all our precautions," one of Fontanilla's colleagues said. "We wear our masks, our shields, our gowns, our gloves, but you never know."

The telemetry nurse was diagnosed with COVID-19 in July and her "condition worsened and she ended up in ICU," according to her GoFundMe page.

"She always had an infectious personality. Willing to help, there with a smile," Fontanilla's friend told CBS Los Angeles. “We wanted everyone to know what an amazing person she was."

"We were rooting for her," the friend added.
