Can pneumonia be transmitted from person to person?
The cause of inflammation of the lungs in adults and children are bacteria and viruses. How do they penetrate the body?
The upper respiratory tract of man is inhabited not only by "good" microorganisms. Among them there are so-called conditionally pathogenic microbes. These are bacteria that normally do not cause any diseases. But if the general or local immunity is weakened, how they are immediately introduced, multiply, and cause the disease.
Can pneumonia be infected with contact, food, water or sexually transmitted infections? No, this development is impossible. Inflammation of the lungs can be obtained only through the airborne path.
Community-acquired pneumonia can occur due to the following factors:
- getting fluid from the oropharynx into the lower respiratory tract;
- inhalation of an aerosol containing microbes;
- spread of pathogens by blood from extrapulmonary foci;
- infection from neighboring affected organs.
In persons with good immunity, the main way to get sick is aspiration of fluid from the pharynx.
Since pneumonia is a consequence of some cold respiratory disease or other infectious process outside the lungs, it can not be infected by airborne droplets.
That's why inflammation of the lungs is not dangerous for others. Infection can only be a disease that led to pneumonia. However, the causative agent of infection in these diseases is not always the same. For example, pneumonia can develop after a viral cold. But the cause of the disease will be not viruses, but a secondary bacterial infection from the oropharynx.
Now we are talking about viral pneumonia. As a rule, the virus that caused the primary disease causes inflammation of the lungs. For example, the influenza virus, especially swine flu, can lead to severe viral pneumonia within 1-2 days. But in this case it is not transmitted from person to person. The patient is contagious to others only in terms of primary disease, and not complications. However, everything depends on the immunity of the person in contact. If it is sufficient, then you can not get sick at all. If not, then the flu can develop. But the development of pneumonia as complications is not necessary. Then how fate will dispose of.
The only form of contagious pneumonia is mycoplasmal pneumonia. It can be transmitted by airborne to the following groups of people:
- children;
- aged people;
- people with weakened immunity;
- people with chronic pulmonary or cardiovascular diseases.
Can children become infected with pneumonia? Again, let's return to the fact that you can catch any kind of bacteria that cause pneumonia. But it does not necessarily occur pneumonia. In the first place may develop ARI. A complication develops against a cold or not, depends on the immunity of the child.That is, the child does not have the opportunity to get infected from others by pneumonia.
The organism of children is especially susceptible to viral pneumonia. If the virus caused pneumonia in a child with good immunity, then this infection is quite dangerous, since it can cause respiratory illness in other children.
Another common cause of pneumonia in children is aspiration of a foreign body. This is especially true for toddlers. Small parts of toys, berry seeds, seeds, etc. can get into the respiratory tract and as a result of prolonged exposure cause pneumonia. Sometimes it is possible to detect the presence of a foreign body in the bronchi of a child only after several relapses of pneumonia. Foreign objects in the airways are not always visible on the roentgenogram, and they often find them only with bronchoscopy.
So, transmission of pneumonia by airborne droplets is not possible. The causative agent, of course, can be transmitted from person to person, but that it will cause inflammation of the lungs is not necessary. The same rule applies to children.
Mycoplasmal pneumonia is an exception. They can infect people with weakened immunity, as well as children and the elderly.

Is pneumonia an issue in search of an answer to an important question?
About whether contagious pneumonia, for a long time heated debate, because until recently it was considered safe for contact. But recently it has been confirmed that it is possible to catch it, it turns out.
In 1994 Large-scale studies were conducted in the US, during which scientists discovered not only that pneumonia is the fourth most common of the diseases that caused death, the most unexpected was that in the pulmonology departments up to 36% of the personnel fall ill to them every year and repeatedly.
In addition, cases of epidemics of pneumonia have become more frequent. As you understand, this would be impossible with an uncontaminated disease.
What can be caused by pneumonia
First of all, it is necessary to understand how they get pneumonia. Most often this occurs against the background of the existing SARS, which greatly reduces the immunity of the sick person - this is where the bacterial or other infection joins the existing problem. In this case, the pathogens that led to pneumonia may be very different:
- viruses;
- bacteria;
- pathogenic fungi;
- protozoa;
- mycoplasma;
- chlamydia.
Any of them, getting into the respiratory tract, quickly spreads through the lungs, disrupting the protective function of the epithelial tissue. And their further rapid reproduction causes the emergence of foci of inflammation.
Each type of pathogen requires its own antibiotic, and that is why it is so important to determine what kind of microbe caused the disease.
Can it be attributed to infectious bacterial pneumonia
As you have probably already realized, pneumonia is not a specific disease that has a specific cause. It can be caused by a number of reasons, and in medicine more than 30 different kinds of pneumonia are known. And only depending on the causative agent of the disease can we talk about whether the pneumonia is contagious.
Thus, bacterial pneumonia occurs when bacteria are infected against the background of existing diseases that have undermined the immune system. And in many cases, the bacterium that caused pneumonia in one person will not cause it who was with him in contact, but it can provoke an infection of the upper respiratory tract, eg. That is, a healthy person who has been in contact with a sick pneumonia can get sick, but this does not necessarily happen to be pneumonia.
Is pneumonia caused by mycoplasma
But if the pathogens of the disease are atypical representatives of microorganisms, for example, mycoplasma or chlamydia, then most often they are transmitted by airborne droplets. Therefore, knowing that your friend or relative is ill with one of these types of pneumonia, exclude or minimize contact with it. Since in this case a healthy person has a high risk of infection.
Which pneumonia is especially contagious
Answering the question about whether pneumonia is contagious for others, it is worth noting that it affects first of all those people who have weakened immunity.
The most dangerous in this sense is the pneumonia that was caught in a medical facility, because in this case the disease is provoked already resistant to antibiotics by bacteria: pneumococcus, hemophilic rod, gram-negative bacilli, pneumoclamidiosis and staphylococcus aureus.
By the way, the most dangerous is the infection with pyogenic flora, as it almost does not lend itself to treatment.
The main signs of pneumonia
Is contagious pneumonia, which is of a community origin, contagious? Her pathogens are most often pneumococci and stick influenza. And this type of disease in general is considered safe for others, but provided strong immunity and compliance with their personal hygiene.
True, in our time, one can not be 100% sure of the strength of one's own immunity, and therefore it is inadmissible to miss and signs of pneumonia. The most obvious symptoms are:
- incessant strong cough;
- the deterioration of the cold that lasts more than a week;
- pain in the chest, not giving a deep breath and causing an attack of cough;
- pallor, fever;
- shortness of breath when walking and during a period of fever;
- its spasmodic increase and a weak effect on the temperature of antipyretic agents.
If any of the signs are present, the patient should undergo mandatory examination for pneumonia.
Pneumonia, which is not contagious
Can I get pneumonia if it is caused by inhalation of fumes of mercury, acids, pesticides or carbon monoxide?
This type of pneumonia is rare, and it is exposed, in the main, to people working in hazardous industries. Harmful substances fall in large quantities into the lungs, causing damage and death of cells. And this, in turn, entails manifestations of the inflammatory process: deterioration of health, cough, debilitating fever, chills and nausea.
But, despite all the signs, chemical pneumonia is not contagious.
A few more words about whether pneumonia is contagious for others
Summing up what has been said, it should be noted that pneumonia itself is not contagious, which can not be said for its pathogens, which can cause the development of pneumonia in other people.
So, arguing, whether pneumonia of lungs is contagious, it is necessary to consider, that it in most cases do not catch, and fall ill. However, in order for this to happen, a person should, as already mentioned, have weakened immunity, and if this is accompanied by a lack of vitamins, stress, hypothermia or exposure to influenza virus, the effect of pneumococcus, which most often stimulates the development of pneumonia, becomes hazardous to health and causes disease.

Whether it is possible to catch a pneumonia lying in hospital in one chamber with the patient ...
Answers:
Stas
Most pneumonias are bacterial in nature, and bacteria are not transmitted by air, infection requires close contact, for example so that the sputum particles fell on the coughing of a sick person on your mucous membranes, but that's not enough, you still need to have some problems with immunity, since staphylococcus, pneumococcus, morocell, or hemophilic rod to a healthy person can not be infected just.
Pneumonia, which is caused by hospital strains of bactriae, is easier to get infected, since infection with such bacteria is small depends on your immunity and they can get infected even a completely healthy person, but for infection again you need a close contact.
Viral pneumonia is a great rarity, but it is very easy to catch them, as many viruses are easily transmitted through the air and close contact is not needed for infection.
So, in principle, pneumonia infection is possible, but the likelihood of this is very low and depends on which pneumonia the people lying next to you were suffering from and the state of your immune system.
Pauline
Yes.. if it is viral in nature
Tolia
probability is... airborne droplets all the same
Zina Zeta
You can not lie in the ward, there are a lot of pathogens, including those that lead to pneumonia and you can get them even on the operating table. In everyday life the same way. Klebsiella is only in medical institutions and can be caught.
Zaikin 77
2Polina: pneumonia is caused by bacteria, as far as I know, so it can not have a viral nature.
I think it all depends on the area of the room and how well it maintains sterility.
But purely theoretically yes, you can get infected.
Just Kseniya
Yes. The main cause of pneumonia is bacterial and viral-bacterial infection. The leading role among pathogenic bacterial pathogens belongs to pneumococci, streptococci, haemophilus rods. The frequency of pneumonia caused by pyogenic cocci, gram-negative rods and anaerobic microorganisms (staphylococcus aureus, legionella, proteus, E. coli, etc.). The main pathogens of nosocomial pneumonia are gram-negative microorganisms and staphylococci.

Easily.
And is pneumonia contagious? Can a child get infected from an adult patient with pneumonia?
Answers:
Etienne Carrier
Yes! naturally)))) So that protect children from patients with pneumonia
Chanterelle
It's contagious. It may get infected, but maybe not. If immunity is good - nothing is scary.
Nikolai Konarev
Elementary! Be careful!
Vyacheslav Sadriev
It is pneumonia that is not contagious. This is not a viral or bacterial disease. The comparison may not be successful, but it is a type of hand injury, as contagious
Yulenk @
Of course contagious. And people happen to get sick in the hospital with pneumonia, lying with appendicitis then bam pneumonia. It is called hospital pneumonia. But not the hospital is not contagious.
Oleg Priblagin
You are not right. Pneumonia can not be infected. Since in the macronutrient of this disease do not multiply not the cell bacteria
Luchina
My son sometimes has to stay at home, because the doctor warns that "just the pneumonia is walking."
Natalia Parshina
if the patient coughs, you can catch the infection itself (not the fact that the child will have pneumonia)

No, it's not... do not listen here some ...)))) it's funny to read the advice of the defendant Yulenka... more delusions have not read ...))))

Can I get pneumonia?
Answers:
Baks Bunny
The correct answer is this: "It depends on the cause of pneumonia, if it is, for example, plague etiology, then yes.
If it's just pneumonia after the flu, then no!
Magnificent
No, pneumonia is not transmitted by airborne droplets.
Michael
No, he can not.
L I X A
Yes,
The most frequent way of penetration of microorganisms into the lung tissue is bronchogenic - and this is facilitated by: aspiration, inhalation of microbes from the environment, the migration of pathogenic flora from the upper parts of the respiratory system (nose, pharynx) to the lower, medical manipulations - bronchoscopy, intubation of the trachea, anesthesia (contaminated artificial respiration apparatus), inhalation of medicinal substances from seeded inhalers etc. The hematogenous path of infection (with blood flow) is less common - with intrauterine infection, septic processes and drug addiction with intravenous drug use. Lymphogenous path of penetration is very rare. Further, with pneumonia of any etiology, there is fixation and multiplication of the infectious agent in the epithelium respiratory bronchioles - develops acute bronchitis or bronchiolitis of various types - from mild catarrhal to necrotic. The spread of microorganisms beyond the respiratory bronchioles causes inflammation of the lung tissue - pneumonia.
Elizaveta Kurichina
Correctly, pneumonia can be only a complication after a transferred disease.
