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

What's the difference between bacterial pneumonia and a bacterial infection of the lungs?

What's the difference between bacterial pneumonia and a bacterial infection of the lungs?

Not much: Pneumonia is usually used to refer to an infection in the clusters of breathing sacs in the lung. I suppose you could say a bacerial infection of the entry of the lung (tracheitis) could be defined better that way but I have never used it that way.To me they would seem to mean the same thing. ...Read more

I know you can get STD through semen but what about bacterial infections like pneumonia or viruses like flu can you get that through swallowing semen?

I know you can get STD through semen but what about bacterial infections like pneumonia or viruses like flu can you get that through swallowing semen?

You are confused: Any organ system can be infected by any number of organisms. By swallowing you get organisms into the GI tract, not the lungs or whatever. Then what you swallow (semen,in this instance) has to be infected. ...Read more

What is the method of transmission in bacterial pneumonia?

Respiratory droplets: Pneumonia is spread from person to person via respiratory droplets released when a person coughs, sneezes, laughs, or talks. The bacteria can live in a person's throat without causing symptoms, so you can even get it from a person who doesn't look sick. Avoid the spread of germs by washing your hands regularly, covering your mouth when you sneeze or cough, and being cautious around sick people. ...Read more

Chloe has bacterial pneumonia. Meant to have 5.25mls twice a day for 2 wks. Seems good but realized after a week I was giving 2.25mls. What do I do?

Chloe has bacterial pneumonia. Meant to have 5.25mls twice a day for 2 wks. Seems good but realized after a week I was giving 2.25mls. What do I do?

No standard rules: These situations are a judgement call. Usually, if a patient was taking half the recommended dose of antibiotics and her symptoms were clearing up, then that lower dose was probably adequate for her illness. If so, one can increase to the recommended dose for the second week. If in the middle of the second week, some of her symptoms are still present, her doctor might want to re-examine her. ...Read more

Is bacterial pneumonia deadly?

It can be: Bacterial pneumonia can be deadly, particularly in the elderly and in people with poor immune systems (on chemotherapy, with hiv, or even uncontrolled diabetes, amongst others). There is a vaccine available to treat one of the most deadly types of bacterial pneumonia, strep pneumonia. Typically, it is given to those at highest risk of developing or having a bad outcome from bacterial pneumonia. ...Read more

Is bacterial pneumonia contagous?

Is bacterial pneumonia contagous?

Not generally: It will obviously depend upon the organism causing the pneumonia and the extent of exposure and your immune status. The short answer is that if this is streptococcus pneumoniae, the most common bacterial pneumonia, as a general rule something in your system predisposes you to this and it is likely to already be resident in the back of the throat. ...Read more

Is bacterial pneumonia more dangerous for children?

Is bacterial pneumonia more dangerous for children?

Yes: Bacterial pneumonia is more dangerous in the extremes of age - the very young and the very old. Their immune systems are sometimes not capable of fighting off the infection on their own and therefore should be treated appropriately in consultation with your doctor. For complicated/difficult cases in children, it may require the expertise of a pediatric pulmonologist to guide therapy. ...Read more

Distinguish between bacterial pneumonia and diphtheria?

Different organisms: Cornynebacterium diphtheria produces illness via toxin that causes inflammation whereas bacterial pneumonia such as strep pneumonia or mycoplasma cause infection by multplying and causing inflmation. This is not to say that diptheria do not multiply, quit the contrary but to stabelize this infection you need antitoxin whereas with bacterial pneumonia, you attack this will antibiotics. ...Read more

Is bacterial pneumonia more dangerous for elderly children?

Is bacterial pneumonia more dangerous for elderly children?

Yes: It is more dangerous in that more severe illness and even death is statistically more common in the very young or the elderly. In both age groups pneumonia is still usually readily treatable with appropriate antibiotics and support. The highest risk of serious illness occurs not just with age, but with the existence of some other underlying disease. (cancer, heart disease, hiv, etc.). ...Read more

How long is bacterial pneumonia contagious to other people?

How long is bacterial pneumonia contagious to other people?

May not be: This will depend primarily on the causative agent of the pneumonia, the severity, how it is being treated and the proximity of contact with the patient. As a general rule, many of the organisms causing bacterial pneumonia are already resident in the nasopharynx and for a variety of reasons the patient has become susceptible to pneumonia, and transmission to others is unlikely. ...Read more

How many days after flu onset would bacterial pneumonia begin?

How many days after flu onset would bacterial pneumonia begin?

At risk: Once the inner lining of the lung is infected, it is prone to a secondary infection. It may take weeks to recover from influenza, and a secondary pneumonia can occur at any time during that period. There is evidence that the risk for a pneumococcal pneumonia occurs even one week after influenza infection.
