The coronavirus has claimed the life of a 96-year-old Texas woman whose sister died from the Spanish flu in 1918, according to a report.

Selma Esther Ryan, who died at an assisted living facility in Austin last week, wasn’t yet born when her sister Esther died 102 years ago at the age of 5, according to WGN-TV.

“On April 3, I got a call from the facility that five residents, including my mother, were running a temperature,” Ryan’s daughter Vicki told the news outlet.

“Over the next five days I watched through the window as she got sicker and sicker. It was so hard to not be with her,” she added. “Her 96th birthday was April 11. Our family gathered outside her window, but it was obvious that something terrible had happened.”

Ryan was not tested for COVID-19 until after she died, Vicki said, adding that the Travis County Medical Examiner’s Office later confirmed her infection.

She was born five years after her sister died during the 1918 pandemic, which proved to be especially deadly for young children.

According to the US Centers for Disease Control and Prevention, the 1918 pandemic infected 500 million people globally — a third of the world’s population at the time — and killed 50 million people, including 675,000 in the US.
