In what way does bacterial pneumonia spread?

In what way does bacterial pneumonia spread?

It does not: Bacterial pneumonia is caused by inhalation of organisms that we are colonized with into the airway. So it is not spread person to person per se. From living our daily lives we pick up germs that live in our mouth and nose, sometimes these germs can get into the lung from aspirating tiny secretions. This is more likely when we are weakened in some way, for example a person is weak with poor cough. ...Read more

Person has stage 4 cancer with mets to the brain, and now has bilateral pneumonia, how bad is this? Is this the cancer trying to spread? What's next?

Person has stage 4 cancer with mets to the brain, and now has bilateral pneumonia, how bad is this? Is this the cancer trying to spread? What's next?

Very bad: The cancer does not have to try to spread, it already has. Discuss this with the person's doctor and get an estimate of how long they are expected to survive and whether it is time to call in hospice. You also need to ask what further therapy is likely to make a meaningful difference in survival and whether that survival is functional or just further misery. Good luck. ...Read more

Hi I'm 22 and have congestive heart failure, the hospital thought it might be from walking pneumonia that spread to my heart, is that possible?

Hi I'm 22 and have congestive heart failure, the hospital thought it might be from walking pneumonia that spread to my heart, is that possible?

Viral disease: Many pneumonias are due to a viral lower respiratory tract infection. Most, if not all, of the viruses that cause lower respiratory tract infections can also cause myocarditis. One of the outcomes of viral myocarditis is the development of a cardiomyopathy and heart failure. In some cases, the heart recovers over the first few months. Heart failure therapy may enhance recovery. ...Read more

What are the causes of pneumomia to rapidly spread in body?

What are the causes of pneumomia to rapidly spread in body?

Depends on the cause: Spread of pneumonia causing organisms (be it a bacteria or virus) depends on the type of bug & immune status of the infected person. Severe infection with an invasive organism in a normal person or if it occurs in a person whose immune system is weak (due to medications, cancer, transplant, hiv, primary immune disorders etc.) then there is a higher chance of spread to bloodstream, causing sepsis. ...Read more
