Hi, I am writing a book based upon a character who is deaf, and I was going to write her cause of this was because of a disease/infection she got early on as a child. I was wondering whether or not there is a disease/infection that can affect her hearing loss, where her general health is not a lot affected, she is able to walk around with everyday activities okay, I mean. I was hoping you can answer my question whether there is such a disease that can make her deaf from the age range of 4-19/20 and then she is able hear things again due to healing, or she was given a certain amount of treatments with medicine. I thought I should also add that this character is based in the times of 1940s, in the era of WW2. If you could reply as soon as possible, I would much appreciate it.
