The National Commission for Women on Monday sought a report from Tamil Nadu authorities over the case of two women allegedly contracting HIV from blood transfusion.

A 24-year-old pregnant woman in Virudhunagar contracted HIV allegedly after being transfused contaminated blood.
Preliminary inquiry revealed that the blood bank staff had failed to screen the blood properly before supplying it to the private hospital. The personnel who tested the donor's blood had labelled it 'safe,' officials said.
The state government had ordered a probe and an examination of all stocks at blood banks in the state after the incident.
The Commission said that a 27-year-old woman had accused doctors at Kilpauk Medical College Hospital (KMCH) of criminal negligence, alleging that she contracted the virus during a blood transfusion procedure in April.
