Rozina Akhtar, who had lost a leg in a road accident in the capital on April 20, died at Dhaka Medical College Hospital yesterday.
Doctors said she had contracted septicaemia, an infection of blood, which might have caused her death.
She was shifted to the intensive care unit (ICU) of DMCH on Saturday as her condition worsened, said Partha Sankar Paul, resident surgeon of the hospital's burn and plastic surgery unit.
Originally from Mymensingh, Rozina had been working as a domestic help in Banani for nine years to support her seven-member family.
Her father Rosul Mia, who cannot work due to frequent illness, said Rozina was the only wage earner in the family.
“Who will look after my family now?” asked Rosul, demanding punishment of the perpetrators and due compensation.
Rozina lost her right leg as a BRTC bus ran over her when she was reportedly jaywalking in Banani around 8:30am.
She was taken to the National Institute of Traumatology and Orthopaedic Rehabilitation (Nitor) and later shifted to DMCH on April 25 after doctors found her suffering from respiratory problems.
The accident happened just three days after college student Rajib Hossain succumbed to his injuries. He had lost a hand after it got stuck between two racing buses in the city's Bangla Motor on April 3.
