A doctor in Chongqing, China, and a patient in Denmark used 5G technology recently for remote diagnosis of an unknown chronic disease.

In January, professor Li Qi in the neurology department of First Affiliated Hospital of Chongqing Medical University received an email from a patient in Denmark. The patient, identified as Sabrina (alias), wrote that she had sought medical treatment in several European countries, including Denmark, Germany and France, over a number of years. But her condition continued to worsen, as the cause could not be found.

A neurologist in France thought Sabrina's disease involved vertebral artery compression syndrome (VACS), a rare disease first defined by Li, the doctor in Chongqing. The patient decided to contact Li directly and request a remote consultation.
