She needs to get a Brainstem Evoked Response Audiometry and upload it here. Certain Viral infections can cause autoimmune damage to the Cochlear Hair cells by the Viral toxins thereby rendering patients deaf. The damage could have been limited by administering medications to increase the Cochlear fluid circulation to eliminate the toxins as soon as pt complains of ear blocks or Deafness but even a small delay results in irreparable hearing loss!
Next Steps
Please take her to the ENT department of Safdarjung Hospital, Delhi, where they have a FREE Cochlear Implant program for the underprivileged who cannot otherwise afford this expensive device.
