Can pneumonia bw transfered from one person to another?

Answer 1

Yes the bacterial one can be passed on,

Bacterial pneumonia

Bacteria typically enter the lung when airborne droplets are inhaled, but they can also reach the lung through the bloodstream when there is an infection in another part of the body. Many bacteria live in parts of the upper respiratory tract, such as the nose, mouth and sinuses, and can easily be inhaled into the alveoli. Once inside the alveoli, bacteria may invade the spaces between cells and between alveoli through connecting pores. This invasion triggers the immune system to send neutrophils, which are a type of defensive white blood cell, to the lungs. The neutrophils engulf and kill the offending organisms, and they also release cytokines, causing a general activation of the immune system. This leads to the fever, chills, and fatigue common in bacterial and fungal pneumonia. The neutrophils, bacteria, and fluid from surrounding blood vessels fill the alveoli and interrupt normal oxygen transportation.


The bacterium Streptococcus pneumoniae, a common cause of pneumonia, photographed through an electron microscope.Bacteria often travel from an infected lung into the bloodstream, causing serious or even fatal illness such as septic shock, with low blood pressure and damage to multiple parts of the body including the brain, kidneys, and heart. Bacteria can also travel to the area between the lungs and the chest wall (the pleural cavity) causing a complication called an empyema.

The most common causes of bacterial pneumonia are Streptococcus pneumoniae, Gram-negative bacteria and "atypical" bacteria. The terms "Gram-positive" and "Gram-negative" refer to the bacteria's color (purple or red, respectively) when stained using a process called the Gram stain. The term "atypical" is used because atypical bacteria commonly affect healthier people, cause generally less severe pneumonia, and respond to different antibiotics than other bacteria.

The types of Gram-positive bacteria that cause pneumonia can be found in the nose or mouth of many healthy people. Streptococcus pneumoniae, often called "pneumococcus", is the most common bacterial cause of pneumonia in all age groups except newborn infants. Another important Gram-positive cause of pneumonia is Staphylococcus aureus. Gram-negative bacteria cause pneumonia less frequently than gram-positive bacteria. Some of the gram-negative bacteria that cause pneumonia include Haemophilus influenzae, Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa and Moraxella catarrhalis. These bacteria often live in the stomach or intestines and may enter the lungs if vomit is inhaled. "Atypical" bacteria which cause pneumonia include Chlamydophila pneumoniae, Mycoplasma pneumoniae, and Legionella pneumophila.

Answer 2

No,pneumonia occurs because the areas of the lungs which absorb oxygen(alveoli) from the atmosphere become filled with fluid and cannot work effectively.Its usually caused by chemical or physical injury to the lungs,or because of another medical illness,such as lung cancer or alcohol abuse.sorry for the long drawn out answer,im a nurse,lol.

Answer 3

Certainly Yes! pneumonia caused by bacteria. This bacteria are called air spread becteria. so pneumonia is likely to spread one person to another by sneezing since pneumonia consist of air to air transmitted bacteria.

Answer 4

bacterial pneumonia is contagious. I had it this fall and I asked my pulmonary Dr the same question and the answer was yes.

Answer 5

No. it is something that develops in your chest and is not a viral infection meaning it can not be passed on...

Answer 6

Yes it could be.

Answer 7

no it cant. my son has it but im perfectly fine.

Answer 8

No

Answer 9

No

Answer 10

no
