A mysterious disease that claimed the lives of five siblings in the past is now gnawing away at the life of the last surviving daughter of a Pakistani mother in Taif.

Two-year-old Mona is fighting for her life after contracting the same disease that killed her five sisters at a very young age.

The disease appears in the form of wounds that gradually grow bigger, forcing amputation of the areas where it surfaces. The mother lost all her five young daughters — Salma, Aamina, Asma, Mariam and Khadija — to the disease.

A medical team at the King Abdul Aziz Specialist Hospital in Taif is working round-the-clock to stabilize Mona’s condition. The child is in need of a special center for diagnosis and treatment, Siraj Al-Humaidan, spokesman of the Ministry of Health in Taif, told Arab News on Sunday.

“The results of all the tests prescribed by doctors will be known in a couple of days — only then will the doctors be in a position to study the case and help her get better,” he said. “If the hospital team is unable to diagnose the disease, Mona will be shifted to a bigger and better hospital in Riyadh.”

Doctors have yet to establish the cause of the illness and plan to amputate the hand where the disease originated.

“The mother brought Khadija, her fifth child, to the hospital when her condition became critical,” said Al-Humaidan. “She died.”

“Now Mona, the youngest child who has been in and out of the hospital, is in a bad condition,” he added.
