Belly Mujinga and another worker were on duty at the Victoria transit station in central London on March 22 when they were approached by an unknown man, reported The Guardian.
On April 2, less than two weeks later, Mujinga was admitted to a local hospital and placed on a ventilator.
The Democratic Republic of the Congo native left behind her 11-year-old daughter Ingrid and husband Lusamba Gode Katalay.
“Belly came home and told me everything,” Katalay told The Guardian.
Mujinga and her colleagues were afraid of contracting coronavirus, but Govia Thameslink Railway, their employer, did not provide personal protective equipment.
