The hearing impairment appears to be genetically influenced, though it can also result from brain damage. While someone who is unable to reproduce pitches because of a lack of musical training would not be considered tone deaf in a medical sense, the term might still be used to describe them casually.
In theory, the contagious period for pneumonia lasts about two weeks, although a person tends to be most contagious when symptoms are at their worst -- which is usually around day two to four of the infection. A person with either viral or bacterial pneumonia is contagious.However, that person's germs are more likely to cause an upper respiratory infection (such as the common cold or the flu) in another person than pneumonia.hese germs are usually found in the mouth and nose of the infected person. They can be spread easily to another person, either through the air or by touching a contaminated surface. Most often, they enter the person's body through the mouth, nose, or eyes.
If your pneumonia is caused by a virus or bacteria, you may spread the infection to other people while you are contagious. How long you are contagious depends on what is causing the pneumonia and whether you get treatment.
