A Liberian nursing assistant, who was named alongside her fellow Ebola fighters as TIME magazine’s Person of the Year in 2014, has died during childbirth.

Salome Karwah, who lived near the Roberts International Airport in Liberia, West Africa, died last week following suspected complications from surgery during the birth of her fourth child, Solomon.

Karwah was an Ebola survivor who had watched many members of her family, including her mother, father, brother, aunts, uncles, cousins and a niece, perish when the disease swept through her village in August 2014. After going “out of her mind” and “mad” for “about one week” following the losses, Karwah decided she wanted to help others affected by the disease, and began work at a treatment centre.

“The first day I came here for an interview, I saw people carrying bodies. I started crying. I told my friend, ‘I can’t make it,’” she told TIME in 2014.

“But when I went the next day I said, ‘Sitting and crying won’t help me. So it’s better I go and work. The more I interact with people, the more I will forget about my sad story.’ So I decided to make myself very much busy to help others survive.”
