According Aarifa's father Amjab Karim Randhawa, Bill Gates telephoned him and expressed his desire about Aarifa's treatment in the US.

Gates has also directed his doctors to ensure every measure for the treatment of the young Microsoft professional.

Gates' doctors contacted Aarifa's Pakistani doctors and received details about the illness through the internet.

Meanwhile, Pakistani doctors are of the view that Aarifa is on the ventilator, therefore it will be hard to shift her to any other hospital.

The 16-year old Aarifa suffered an epileptic attack on December 22 in 2011, which affected her brain and heart causing her to slip into a coma. She has been on a ventilator since then.
