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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
Can I get infected from a patient with pneumonia?Thinking about the question whether pneumonia is contagious or not, we must precisely determine what is included in the concept of "infectiousness". The disease is contagious if it is capable of being transmitted from a sick person to a healthy one by any means and causing the same pathology and clinical symptoms.
Pneumonia is an inflammation of the lung tissue. Doctors know more than 30 of its varieties. It can be caused as infectious agents, and toxic substances, pesticides from the external environment.
Where do infectious germs come from?
Most people get contagious microbes from the external environment: from the air when breathing, through contaminated foods, unwashed hands. And in the natural environment microorganisms are allocated by sick people and animals.
It is not a fact that when a healthy person enters the nasopharynx, a disease develops. A strong organism will not allow pathology. Immune cells are always ready to repel an "attack" of uninvited aliens. But with a decrease in protection, which is caused by unfavorable conditions, stress, physical activity, other diseases the body loses protective functions and "allows" pathological microorganisms to work at full strength.
Part of the infection lives in chronic foci for a long time without showing any effect. These are maxillary sinuses, carious teeth, gall bladder, intestines. Any untreated chronic processes pose a threat to a person.
Such a serious pathology as pulmonary tuberculosis can be long hiding in the lymph nodes. When activated without appropriate treatment, causes caseous pneumonia with complete disintegration of lung tissue. Can I get pneumonia from such a patient? The risk is very high, but in fact one can only predict the incidence of tuberculosis among the contact persons. And what form of the disease will arise beforehand can not be known.
In recent years, great importance is given to the nosocomial pathway of infection. There is a high risk of infection of personnel working in pulmonology departments in purulent surgery. In this case, infectious agents are particularly strong and resistant to antibiotics, as they "grew" among them.
Employees most often fall ill with pneumonia. The medical statistics of some studies indicate that 36% of staff are ill each year.
Selectivity of lung lesions is associated with a high concentration of infection in the air and droplet transmission. Those around should wear masks and change them regularly, and inside the department a sanitization regime with disinfectants and a regular inclusion of bactericidal lamps are necessary.
What microbes most often cause pneumonia
Is pneumonia invasive or not when treated at home? For family members living together, it is important to prevent the spread of the infection. It stands out when coughing, breathing, talking with small droplets of saliva. But the facts that the contact person will get the inflammation of the lungs is not.
The most dangerous damaging factors are the following microorganisms:
- Staphylococcus aureus,
- influenza virus,
- pyogenic streptococcus,
- causative agent of legionellosis.
They are prone to high prevalence, are capable of damaging immune cells and are sensitive to lung tissue.
Who gets pneumonia more often
We list the contingents with a high risk of pneumonia for any infection.
- People suffering from various chronic diseases.
- Postponed surgical interventions.
- Patients oncology dispensary after the course of radiation therapy.
- Patients receiving hormone therapy.
- Pregnant women and women in the postpartum period.
- People who survived stressful situations, depression.
- Patients after the transferred infectious diseases (including after the flu and respiratory infection).
- Alcoholics and drug addicts.
These conditions contribute to a significant weakening of immunity. The body needs protection for the recovery period.
People who are prone to frequent catarrhal diseases should not once again contact patients with pneumonia. The appearance of a strong cough in the flu, chest pain, dyspnea should serve as an alarm for the patient, requires examination and early treatment.
L.N. Mishchenko, the doctor.
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.
No, not contagious ....
Yes. And transmitted by airborne droplets. In the common people, pneumonia.
Personal Cabinet Removed
YES it is unreal!
No. Pneumonia is an inflammation of the lungs. It is not transmitted in any way! Quietly visit!
not, infectious is the inflammation of the lungs to another
Personal Cabinet Removed
No (if it's exactly pneuma)
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!
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 has struck the finest, most tender pulmonary vesicles-alveoli, complicated their work - to saturate the blood with oxygen and to release it from 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 suppuration 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.

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.
there is not contagious unless it becomes tuberculosis. but this process is lengthy.
No, it's not contagious. My friend was ill with pneumonia, I have nothing, I'm not sick.
How is pneumonia manifested in adults and children?
- In adults
Anyone can get pneumonia.
This disease is usually a complication of respiratory infection, especially the flu, but there are more than 30 different causes of the disease.
Elderly people, children and people with chronic diseases, including bronchial asthma, have a high risk of developing pneumonia.
Most of the time, filters in the nose and airways screen out germs from the air. This saves the lungs from infection.
But microbes sometimes find a way to penetrate the lungs and cause infections.
This is more likely to happen when:
- The immune system weakened.
- Disease-causing microorganisms are present in large quantities.
- The body can not filter out germs from the air that a person breathes.
When the microbes that cause pneumonia reach the lungs, airy lung vesicles (alveoli) become inflamed and filled with fluid. This causes symptoms of pneumonia, such as coughing, fever, chills and breathing problems.
Inflammation of the lungs is contagious?
- People can get infected from each other by microbes that cause pneumonia. These microorganisms are present in the most crowded places and the environment.
- Children who go to school or kindergarten can easily "catch" viruses from each other, which makes them more prone to viral pneumonia.
- Viral pneumonia is more contagious than bacterial or fungal. This is because viruses are more often transmitted from person to person.
- Some types of pneumonia are contagious only under certain conditions. For example, Legionnaires' disease, which is caused by Legionella bacteria, can be contagious only for people exposed to polluted air conditioning.
- The chance of developing a disease in a person with microbes that cause pneumonia in the body depends on his age, health and lifestyle.
How is pneumonia manifested in adults
Symptoms of pneumonia can range from mild to severe.
The most common symptoms of pneumonia are:
- Cough (with greenish, yellow or even bloody mucus).
- A fever that can be mild or severe.
- Shortness of breath, which can occur when the patient climbs the stairs.
Additional symptoms include:
- The feeling of tingling or pain in the chest, which increases if you breathe deeply or cough.
- Excessive sweating and stickiness of the skin.
- Loss of appetite and fatigue.
The signs of pneumonia may vary depending on what kind of pneumonia - bacterial or viral.
- With bacterial pneumonia, the temperature can rise to 39-40 degrees.
- This type of pneumonia causes profuse sweating, rapid breathing and rapid heart rate.
- Lips and nails can have a bluish color due to a lack of oxygen in the blood.
- The mental state of the patient worsens, confusion may arise.
The initial symptoms of viral pneumonia are the same as the symptoms of influenza:
- Dry cough.
- Pain in the muscles and weakness.
- During the period from 12 to 36 hours, shortness of breath increases, cough becomes worse and with it a small amount of mucus is expectorated.
- High temperature and blue lips are also manifestations of viral pneumonia.
How is pneumonia in children?
- Pneumonia accounts for 13% of all infectious diseases in children under the age of 2 years.
- In newborns with pneumonia, there is usually a poor appetite and irritability, as well as rapid breathing, retraction (retraction of intercostal spaces) and hypoxemia (decrease in the level of oxygen in the blood).
- Infections such as Group B Streptococcus, Listeria, or Gram-negative rods (eg E. coli, Klebsiella pneumonia) are common causes of bacterial pneumonia. Group B streptococci are most often transmitted to the fetus in the womb.
- Cough is the most common symptom of pneumonia in young children, along with apnea and hypoxemia. This can be accompanied by fever, irritability and loss of appetite.
- Pneumococcus is today the most common bacterial pathogen in children aged 1-3 months.
- Adolescents experience symptoms similar to those of young children. To this may be added headache, chest pain and abdominal pain. Vomiting, diarrhea, pharyngitis and acute ear pain (otitis) are also common in this age group.
- Mycoplasma pneumonia is the most common cause of pneumonia in older children and adolescents.
What are the risk factors that increase the chances of developing pneumonia?
- Smoking cigarettes.
- Postponed viral respiratory infection, cold, laryngitis, influenza, etc.
- Difficult swallowing (as a result of stroke, dementia, Parkinson's disease or other neurological condition).
- Chronic lung diseases, such as bronchiectasis or cystic fibrosis.
- Cerebral palsy.
- Other serious diseases, such as heart disease, liver cirrhosis, diabetes mellitus.
- Life in a home for the elderly.
- Impaired consciousness (loss of brain function due to dementia, stroke, or other neurological conditions).
- Recent surgery or injury.
- Weakened immune system due to illness, some medicines and autoimmune diseases.
How is pneumonia manifested in the complication of the disease?
If a patient has flu-like symptoms that persist or worsen despite treatment, talk with your doctor. In order to confirm the diagnosis, the doctor can prescribe a chest X-ray, and also take a sample of sputum and write a direction for a blood test. Be-treatment of inflammation of the lung can lead to very serious consequences.
- So, viral pneumonia can quickly progress to respiratory failure.
- The most common complications of pneumonia include pleurisy and bacteria in the blood. With pleurisy, fluid accumulates in the layers of tissue between the lungs and the wall of the chest. This can make breathing difficult. For the treatment of pleurisy, surgical intervention may be required.
- Bacteria in the bloodstream appear when the pneumonia infection in the lungs spreads into the blood. This increases the risk that the infection will spread to other organs. Bacteria in the bloodstream are treated with antibiotics. People who have heart or lung problems, smokers and elderly people over 65 are more likely to experience complications from pneumonia.
How can I prevent pneumonia?
- Do an inoculation against the flu every year. People often get bacterial pneumonia, which develops after the flu. Vaccination against influenza does not protect against all strains of influenza, only from 3 -4 strains, which doctors consider the most dangerous or common in the coming year.
- Do not forget about hygiene. Man's hands come into contact with many microbes throughout the day. Microorganisms can be on the door handles, computer keyboard, etc. That's why you need to wash your hands often (with warm water and soap, 20 seconds minimum), especially after going to the toilet and before eating. If soap and water are not available, an alcohol-containing hand sanitizer can be used.
- Do not smoke. Smoking damages the lungs and weakens the body. In general, the prognosis for pneumonia is good. Long-term change in lung function is rare, even in children with pneumonia, which has been complicated by empyema or lung abscess.
Is pneumonia contagious?
I wonder if inflammation of the lungs can be dangerous for others? Before deciding whether pneumonia is contagious, it is worthwhile to understand the subtleties of the clinical picture of the disease.Causes of pneumonia
Inflammation of the lungs leads to infection with pathogenic microorganisms. Among them:
It would seem that the infectious nature of the disease itself answers the question. Nevertheless, it is contagious whether pneumonia for others largely depends on the type of pathogen, as well as the state of immunity of a person in contact with the patient.
Is viral pneumonia viable?
Most often, pathology is a complication of the catarrhal disease caused by viruses. In this case, the risk of infection is minimal. Infection is transmitted by the usual respiratory illness by airborne droplets. Therefore, before entering the lungs, the pathogen has to "master" the nasal passages, larynx, trachea and bronchial tree.
The gradual procession of pathogenic microorganisms in the respiratory system is accompanied by a number of clinical symptoms:
- deterioration of the general condition;
- increased temperature;
- shortness of breath.
All these signs allow you to identify the infection and conduct treatment before the microorganisms get to the lungs.
There are forms of pneumonia that can not be dangerous to others. For example, pneumocystis pneumonia can not be infected, since pathology is caused by Pneumocystis jirovecii. This fungus is present in the lungs of any person and begins to multiply rapidly only with a decrease in immune defense.
What forms of pneumonia are contagious?
The most dangerous for others include the following forms of pneumonia:
The basal pneumonia can be infected, since the infectious process is localized in the lower lobe of the organ. Because of this, the symptoms of the disease resemble common ARVI and treatment often does not have a positive effect. If a person with a weakened immune system is in contact with the patient, it is likely that pneumococcal infection occurs. The risk increases if the pathology is not detected in a timely manner.
Congestive pneumonia is a secondary pathology and develops as a result of blood stagnation in the bronchi or lungs.
The most contagious two-sided pneumonia of the focal type. In this case, the pathology may not give characteristic for inflammation of the lungs symptoms.
The risk of contracting atypical pneumonia caused by infection is, on the contrary, minimal. Most often, infection with pathogenic microorganisms leads to catarrhal diseases.
Chronic pneumonia, like other infectious diseases, is contagious during the period of exacerbation. During remission, the disease is not dangerous to others.
Cavernous form is a subspecies of tuberculosis. The disease is characterized by rapid flow, severe complications and a high risk of infection.
The bronchial type can be contagious with weakened immunity.
Serious danger is hospital pneumonia. The disease is caused by herpes, streptococcus and staphylococcus, E. coli, which are adapted to most medications. Already from the name of the disease it is clear that getting infectedpathology is possible within the walls of a medical institution. The hospital personnel are most often exposed to microorganism attacks, it can also become a carrier of pathogens. Since the pathogenic microflora is resistant to most antibiotics and other pharmacological preparations, the percentage of deaths is high.
As a rule, pneumonia is contagious and after the disappearance of symptoms. The causative agents spread to a decent area, settle on furniture. Therefore, infection can occur by the household way. To avoid problems, you should often clean the patient's room, ventilate the room, and strengthen their immunity.
Is pneumonia present?
It is unlikely to become infected with pneumococcus or legionella, for example, but there are different forms of different virulence.
In itself, pneumonia is not contagious. It is a bacteria or a virus that provoked pneumonia.
That's such a life
she is different
Some of its subtypes (specific) of pneumonia-caseous, mycoplasmal, chlamydial and others are contagious.
Pneumonia is a group of diseases of various origins. Some species can be transmitted by airborne droplets. But it's not as easy as influenza or ARVI. The body should be weakened, there must be factors provoking this transfer.
In itself, pneumonia is not contagious, it is rather as a complication in k-l infectious or viral diseases. for example with influenza. If the person's immunity is strong, has sustained a course of treatment, then pneumonia may not occur. It can be picked up in a hospital (so-called. hospital or nosocomial pneumonia), and this is the worst option. since the pathogen is usually NOT SENSITIVE!! ! to many antibiotics, and it is necessary to treat at times not one, but a whole arsenal of means. So it's better not to get sick or at least not allow illness !!))
