Professor Hadiza Abdullahi Usman, who serves as the Medical Director of the [Federal Medical Centre, Nguru](https://fmcnguru.gov.ng) in Yobe State, has suffered the loss of both of her twin daughters – Dr. Hadiyah Usman Abdullahi, a physician, and Aidah Usman Abdullahi, a pharmacist – within a span of two days.
Hadiyah died on Friday, 2 October 2026, while her sister Aidah passed away two days later on Sunday, 4 October 2026, each succumbing to complications linked to [sickle cell disease](https://en.wikipedia.org/wiki/Sickle_cell_disease).
Hadiyah had been admitted to the FMC Nguru for roughly a week after experiencing a sickle cell crisis, and she died on Friday.
During the same timeframe, Aidah was under care at the [University of Maiduguri Teaching Hospital](https://umth.edu.ng); she was initially reported to have recovered and was sent home.
Hadiyah’s burial took place on Friday after funeral prayers were performed at the Emir’s Palace.
Two days after the funeral, Aidah went to pay respects at Hadiyah’s grave.
According to reports, she suddenly collapsed at the gravesite, was hurried to a hospital, and subsequently died.
The Federal Medical Centre, Nguru later confirmed Aidah’s death via a Facebook announcement, referring to her as the “second twin” of Professor Usman.
Professor Usman holds a chair in Gynaecological Oncology and Reproductive Health and was the first female consultant obstetrician‑gynaecologist to graduate from the University of Maiduguri Teaching Hospital.
She attained the rank of professor in 2018 following extensive experience in both clinical practice and academia.
In November 2022, she was appointed as the fourth Medical Director and Chief Executive Officer of FMC Nguru, becoming the first woman to occupy that role.
