How is pneumonia transmitted?

Pneumonia is a type of acute respiratory infection that damages the lungs. The disease is the main cause of death of children under 5 years. The disease is caused by various bacterial, viral, fungal microorganisms and can be transmitted by airborne droplets.


  1. Most often, pneumonia is transmitted from an already infected person. It is sufficient for the recipient to inhale the air particles in which pathogenic microorganisms are present in order to get an infection. Nevertheless, when transmitting bacteria and viruses in this way, the uppermost respiratory organs (cold or flu), rather than the lungs, are most likely to be affected. Subsequently, pneumonia can already occur as a complication of the disease. Infection is caused by streptococci (Streptococcus pneumoniae) and Hib (Haemophilus influenzae type b).
  2. The disease is often the result of viral damage, such as measles or chicken pox. The probability of infection depends on the ability of the body's immune system to resist the pathogenic environment that forms in the human lungs. Smoking, alcoholism and polluted air often provoke the development of pneumonia. Diabetes, chronic obstructive pulmonary disease, HIV (AIDS) are also risk factors.
  3. The period during which the disease can be called contagious depends on the pathogen. In some viruses, the ability to spread by airborne droplets appears 2-3 days before the onset of human manifestation of any symptoms and persists until complete cure. Theoretically, pneumonia is contagious within 2-3 weeks, however the highest probability get an infection from its carrier observed at the peak of the illness, which usually lasts 2-4 day. The incubation period is from 2 to 10 days. Its duration depends on the age, health and aggressiveness of the virus or bacteria.
  4. Prevent infection by observing the basic rules of hygiene. For example, you should regularly wash your hands. Do not touch various objects to the nose, mouth and eyes. It is necessary to temporarily limit the number of contacts with sick people who are carriers of the disease. Do not use dishes, cutlery and toothbrushes of an infected person. Proper nutrition will improve the defenses of the body.
  5. Treatment of pneumonia is carried out with the help of antibiotics. In most cases, the use of antibacterial agents, produced in the form of tablets, is acceptable. Hospitalization is permissible in cases of severe illness or in all cases of illness in children who were born less than 2 months ago. In case of viral infection, it is possible to administer specialized antiviral drugs.

How is pneumonia transmitted?

Inflammation of the lungs is a rather dangerous disease. With improper treatment, it can occur with complications. Bacteria and viruses that cause pneumonia can be transmitted by airborne droplets. However, this disease can not be considered infectious.


  1. Inflammation of the lungs is viral and bacterial. In the first case, its causative agents are pathogenic viruses. Bacterial pneumonia is caused by pathogenic fungi, mycoplasmas, chlamydia, protozoan microorganisms. Inflammation of the lungs is not a contagious disease, but this does not mean that you do not need to be afraid of contacting patients.
  2. Transmission of viruses that cause pneumonia occurs by airborne droplets. In this case, pneumonia can develop only if a healthy person is weakened by immunity, he experiences stress, fatigue. Provoke pneumonia can and hypothermia. Thus, infection with viral pneumonia occurs against the background of a weakening of the body's defenses and the impact of disease-causing viruses on it.
  3. A person with stable immunity on contact with a sick pneumonia, as a rule, does not get sick, or suffers from an ordinary cold. In order to protect themselves, it should, whenever possible, avoid being in crowded places during the epidemic of colds. If one of the members of the family becomes ill, it is necessary to make sure that he uses individual cutlery.
  4. Bacterial form of pneumonia is not contagious, even indirectly. Infection occurs due to the penetration of pathogenic microorganisms into the lungs. They very quickly multiply, resulting in a foci of inflammation. Disease-causing microbes can enter the human body after communicating with their carriers, as well as after contact with infected surfaces.
  5. Just as in the case of viral pneumonia, bacterial pneumonia, a person can become infected only if his body is weakened and supercooled. After a long stay in the cold, all protective functions are weakened, the pathogenic bacteria existing everywhere, penetrate the respiratory tract and cause inflammation.
  6. The best prevention of pneumonia is proper nutrition, proper rest, timely treatment of colds, careful treatment of one's own health. In the cold season, in no case can you be supercooled, breathe through the mouth in the cold. If you find the first symptoms of the disease should immediately seek medical attention.

I wonder if the pneumonia is contagious or not

Pneumonia is contagious or not? This question can be safely answered "yes but the probability of infection with pneumonia directly depends on what caused the disease. Since it is the pathogen of pneumonia that determines the nature of the course, the severity of the disease and the degree of its danger to surrounding people.

The problem of pneumonia

Types of pneumonia

A universally recognized classification of pneumonia does not exist, but doctors distinguish the following types of disease, depending on the nature of the pathogen:

  • bacterial pneumonia;
  • viral-bacterial;
  • fungal.

It should be noted that recently in medical practice the term "pneumonia" or "pneumonia" is understood not as a chronic, namely acute inflammatory process in the lung tissue.

Thus, this disease is especially acute.

A few words about the causative agents of pneumonia

Staphylococcus is the cause of pneumoniaMost often, pneumonia occurs due to infection with bacteria of various kinds (gram-negative and gram-positive anaerobic bacteria), namely:
  • pneumococci (or streptococci pneumonia);
  • staphylococci;
  • a hemophilic rod;
  • klebsiella;
  • intestinal and pseudomonas aeruginosa;
  • proteome;
  • legionella;
  • anaerobic microbes (bacteroids, clostridia, etc.);
  • chlamydia;
  • mycoplasmas.

These pathogens are transmitted by both airborne and other routes, for example, through dust, household items, mucous membranes of the digestive tract, placenta, and the like.

It must be said that the disease with pneumonia can be caused by fungi and protozoan microorganisms, for example pneumocysts. The path of data transmission of pathogens of pneumonia is mainly airborne.

In addition to bacteria, fungi and protozoa, an important role in the disease of pneumonia is played by various viruses. These are viruses that cause such infectious diseases as influenza, parainfluenza and ARVI, as well as adenoviruses, reoviruses and herpes viruses. As a rule, they are transmitted from the sick person by the surrounding airborne pathway (pathogens ARVI), alimentary (through the mucosa of the gastrointestinal tract - adenoviruses and reoviruses). These infectious agents are contagious and cause the disease pneumonia of the viral etiology. Inflammation of the lungs of a viral nature usually lasts 1-3 days, then a bacterial infection joins the virus infection, and pneumonia acquires a viral-bacterial character.

Blood test for diagnosis of pneumoniaIt is in the first 1-3 days that viral pneumonia is the most contagious, because the infectious agent that caused it is very aggressive, has a high contagiousness and, accordingly, is actively transmitted by airborne droplets from the patient to a healthy sensitive person.

In addition to the aforementioned bacteria, viruses and fungi, the cause of pneumonia can be caused by pathogens of such dangerous infectious diseases, Salmonella, sap, plague, leptospirosis, chicken pox, scarlet fever, measles, etc. As a rule, these diseases are caused by different bacteria. Infectious agents of this kind are transmitted, in addition to alimentary and airborne droplets, also transplacental (through the placenta - from mother to fetus). In addition, pneumonia can infect the body of a patient with several infectious agents, for example, the influenza virus and streptococcus pneumonia. Not infrequent are other combinations of pathogens.

Diagnosis of pneumonia

The most reliable method of diagnosing the disease is radiographic. In addition, a blood test and various bacterial cultures are required.

It is necessary to say that it is not enough to perform bacterial culture alone to diagnose pneumonia sputum, because it is necessary to identify a pathogenic microorganism on the basis of bacteriosomes of blood, lung tissue and pleural liquid. The data of these studies determine the choice of drugs and the scheme of treatment of the disease. As for bacterial culture of sputum, a whole series of conditionally pathogenic microorganisms, any of which under certain conditions is capable of causing an inflammatory process in the pulmonary tissue. As for fungal pneumonia, the diagnosis of such diseases is the most complex and complex.

Danger of pneumonia of different etiology

Weak immunity - the cause of pneumoniaSo, is it possible to get pneumonia? Unfortunately, yes, but the probability of infection depends on the specific pathogen and the severity of the disease. As already noted, the most common and dangerous in terms of intensity and speed of infection is viral pneumonia that occurs on the background and due to catarrhal viral diseases etiology. And viral pneumonia is equally dangerous for anyone, regardless of the age and condition of the human immune system. Good immunity only speeds up recovery and helps to ensure that the disease is mild.

After 1-3 days, a bacterial infection is attached to the viral pneumonia, which, like the virus, is very dangerous to surrounding people, because infectious diseases of a bacterial nature are high contagiousness.

It must be said that both bacterial and fungal inflammation of the lungs is especially dangerous for young children and for people with weakened immunity, as well as for those who directly contact the sick person - medical staff, relatives and other In addition, bacterial pneumonia is easily spread in narrow "closed" collectives - among servicemen, watch brigades, etc. Special At-risk smokers are heavy smokers whose respiratory and cardiovascular systems experience increased stresses associated with exposure nicotine.

As for pneumonia due to some epidemiological infectious disease, we can say that pneumonia of this kind is not dangerous in and of itself, but due to the high likelihood of contamination surrounding a particular infectious disease, which was the cause of pneumonia, for example, measles, plague, anthrax and other


Is pneumonia a fungal etiology? Is pneumonia caused by fungal microorganisms transmitted? In the case of fungal inflammation of the lungs, as a rule, such diseases are most dangerous for people with reduced immunity, or for those who, in the nature of their professional activities, often come into contact with fungi of different kind.

Such professions include workers in certain sectors of the food, woodworking industry and agriculture, in particular, paper production, feather brewing, brewing, meat production and other It must be said that fungal pneumonia, or pneumomycosis, is difficult to treat. And an important role in this is played by the complexity of diagnosis and specific symptoms similar to those of a number of other diseases.

In general, it can be concluded that this disease is contagious, and inflammation of the lungs of any etiology is a dangerous infectious disease.


Therefore, to prevent infection when contacting a sick person is necessary follow the rules of personal hygiene and follow medical instructions governing the treatment of infectious patients.

Pneumonia is a contagious disease?



It depends on what it appeared - there is simply a catarrhal-weakened variant, but there is a nasty-viral-viral. Ask your colleague, explain your fears, I think she does not want to harm your children, let them say for sure, contagious or not. Although once at home, and not in a hospital, most likely, for others is not dangerous.

Oksana Gerasimova

No, not contagious ...

Free Sweeper

Yes. And transmitted by airborne droplets. In the common people, pneumonia.

Personal Cabinet Removed

YES it is unreal!

Evgenia Loginova

No. Pneumonia is an inflammation of the lungs. It is not transmitted in any way! Quietly visit!

Dmitriy Sergeevich

not, infectious is the inflammation of the lungs to another

Personal Cabinet Removed

No (if it's exactly pneuma)

Vovchik I

Pneumonia, it is in the people pneumonia. I was sick. For a long time, and my husband took care of me, he would at least have something!

Uncle Vitya

it's an elementary inflammation of the lungs!
there is little good, but there is no infectiousness ...
kissing, however - I do not recommend... this is another charge of bacteria for the patient.


Pneumonia. Pneumonia, or pneumonia, is a group of diseases that is characterized by inflammation of the lung tissue. This diagnosis means that the inflammatory process in some area struck the finest, most delicate pulmonary vesicles-alveoli, complicated their work - to saturate the blood with oxygen and to release it from the carbon dioxide. The urgency of the problem of pneumonia lies in the persisting high incidence. There remains high hospital lethality.
Predisposing factors to the disease of bronchitis or pneumonia are chronic inflammatory and suppurative processes in the lungs, chronic foci of infection in the upper respiratory tract, decreased immunity, hereditary factors. The main mechanisms of development of chronic bronchitis include hypertrophy and hyperfunction of bronchial glands with increased secretion of mucus, which increases the viscosity of phlegm. Under these conditions, the ciliated epithelium does not provide emptying of the bronchial tree, the drainage of the bronchi occurs only with coughing. Disturbance of the drainage function of the bronchi promotes the emergence of an infection whose activity and relapses are largely dependent on local bronchial immunity.

Munzwir Barkashev

If you do not kiss then there is no


No pleurmonia is not a contagious disease, it's just a cold. This is not a disease that is transmitted by airborne droplets.


No, it's not contagious. just a man caught cold, then froze, started. This is a lung disease that is not transmitted. Visit your colleague.

MARGO 1234

there is not contagious unless it becomes tuberculosis. but this process is lengthy.

Katya Katya

No, it's not contagious. My friend was ill with pneumonia, I have nothing, I'm not sick.

Can a person get pneumonia from another person?? for example when communicating? for example when communicating?


Alexander Mylnikov

Can not. Pneumonia is not a contagious disease.

Lilia Pichuzhina


Elliott J-Di

can, and if it is a viral pneumonia, then the probability is even higher.


forms of pneumonia are many.. there are among them and infectious.. for example, nosocomial pneumonia ...


Very unlikely!

Yulia Yegorovskaya

It is possible, but as a rule this rarely happens.
Pneumonia is not very contagious.

cyril borodin

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.

Lydia Alexandrovna

If close contact and weak immunity... -and this is unlikely... otherwise all pulmonologists and therapists would be ill ...


pneumonia is not contagious. This is pneumonia. That's only in China in a certain year was atypical pneumonia, it was contagious. But, they say, it was a biological weapon. To believe in it or not is a private matter for everyone


can, if it is viral, or if a person is weakened. So the mask mode is relevant

galina russian (churkin) GALJ

all sores are contagious, from viruses and germs. and it is especially dangerous for someone with weak immunity.

Elena Filatova

Can not. Pneumonia is not a contagious disease.
As for viral pneumonia. then their name indicates only the affected organ, and not the etiologic factor that caused the infection.
The most common causes of viral pneumonia are:
Influenza virus subtype A and B
The respiratory syncytial virus (RSV)
Paragrippus (in children)
Also, viral pneumonia is caused by more rare viruses:
The SARS virus (Severe Acute Respiratory Syndrome), also known as "SARS"
Other varieties of viruses can only in some cases cause pneumonia:
Herpes simplex virus (HSV), more often leads to the development of pneumonia in newborns
Chicken pox virus
Cytomegalovirus, often causes pneumonia in people with reduced immunity

Lyudmila Stroganova

Pneumonia as a disease is an inflammation of the lungs, it is almost impossible to catch it, but you can pick up an ARI that can go into pneumonia ...
