Greetings and thank you for using justanswer,
Who are the persons infected with ear infection apart from your sister?
How long are they having symptoms?
Did they consult any doctor yet?
As per the symptoms you described me , it seems that your friend is suffering from CSOM that is Chronic suppurative otitis media which commonly causes such symptoms of ear discharge, ear pain, and loss of hearing which may be fatal if left untreated and if the infection spreads to meninges.
You should counsel your friend that you have CSOM and needs to be treated otherwise it may be fatal.This way she may agree and when treated she will become non-infective for your children as well.Her children should also be treated.
The CSOM is infectious and the bacteria may be transmitted and may cause the infection with chronic close exposure
