I get pneumonia about every other year and my daughter has had it a few times and usually I am out of work and she is out of school at LEAST a week- have never been back before that! I typically end up with pneumonia after catching a cold from my daughter- she will have a slight cold, I will get pneumonia....
As far as it being contagious.....
Is pneumonia contagious?
So, we're back to the original question, "is pneumonia contagious".
Pneumonia in itself it usually not contagious but the organisms, particularly the viruses, that cause pneumonia can be contagious.
Pneumonia can be caused by the same viruses that cause the common cold or influenza and these viruses can be passed from person to person. You may just have a cold but someone else may get a pneumonia. From that point of view, the virus is contagious but not the pneumonia.
When your child has a "cold" or pneumonia it it important to take care to prevent spread of viruses by hand-washing so you minimise the infection being contagious. Also teach your child to cover her mouth when coughing or sneezing.
To prevent the viruses that can cause pneumonia being contagious, it is wise to keep your unwell child away from other children and to keep your well child away from children who may be unwell.
Some conditions causing a type of pneumonia such as tuberculosis are very contagious and you should see your doctor if you have been in contact with someone with tuberculosis. This pneumonia is contagious.
So overall, unless you have tuberculosis, the answer to the question "is pneumonia contagious" is "no", but take precautions not to spread the germs that can cause pneumonia when you or your child is not well.
