How is pneumonia transmitted from person to person?

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.

Pneumonia is contagious or not?

Pneumonia is an acute infectious disease of the lungs, or simply inflammation of the lungs. The incidence of pneumonia among the world's population is astounding by their numbers, annually more than 2 million are registered in Russia alone. cases of development of this disease.

If we consider pneumonia as the cause of mortality, then it stands firmly in 4th place, after cancer, heart attack and stroke.

Children, weakened and elderly people are most often affected by pneumonia. The insidiousness of pneumonia lies in the fact that the causative agents of the disease can act and bacteria, and viruses, and fungi, and atypical pathogens:

• Bacteria
• Viruses
• Anaerobic pathogens
• Mycoplasma, chlamydia
• Rickettsia - fever
• Fungal etiology of pneumonia

Is pneumonia invasive or not? Even doctors do not give an unambiguous answer to this question. To understand this issue, you should consider what are the types of pneumonia:

• Community-acquired pneumonia

If we consider inflammation of the lung from the point of view of the causative agent of the disease, then bacterial, ordinary pneumonia, medicine is recognized as not a contagious form of inflammation. In most cases, pneumonia is a complication of SARS, parainfluenza, influenza, rhinovirus, especially in children. If the virus caused an inflammatory process in the lower respiratory tract, then in the bronchi, the lungs accumulate mucus, pus. This complicates the ventilation of the lungs and leads to the accumulation of bacteria. And of course with a cough, sneeze, a loud conversation, the patient releases into the air the pathogen of pneumonia. If a person's pneumonia was triggered by a virus, then the contamination of others may be by airborne droplets, but only the primary cause of the disease, that is, acute respiratory viral infection or influenza. But whether the pneumonia develops for the infected, directly depends on the protective forces of the affected organism, on the timeliness and adequacy of the treatment of this virus.

• Dangerous, infectious types of pneumonia

If the causative agent is tuberculosis (caseous pneumonia) or atypical representatives such as chlamydia, mycoplasmas, SARS (type of atypical pneumonia, which is called a severe acute respiratory syndrome), then such forms of pneumonia are transmitted from person to person airborne droplets. It is encouraging that these types of diseases rarely cause epidemics and occur in isolated cases. If a person who is in contact with such a patient has weakened immunity, then the probability of infection with such dangerous forms of pneumonia is very high. Pneumonia is contagious if its pathogens are: chlamydia, mycoplasma, klebsiella, legionella, Staphylococcus aureus, Streptococcus pyogenes, Haemophilus influenzae, Chlamidiapsittaci, Coxiella burnetii.

• Hospital pneumonia

Studies conducted in the United States for infection of health workers serving in pulmonological offices, found that employees of these departments suffer respiratory diseases more often than other citizens countries. Namely, the incidence of pulmonary medical personnel was more than 35% per year. That is, the medical staff of these departments has a high risk of contracting hospital pneumonia, and many of the workers have suffered pneumonia even several times. The causative agents of hospital pneumonia are often gram-negative bacteria, anaerobes, chlamydia, staphylococcus, streptococcus. It is hospital pneumonia that causes the high mortality from this disease (almost 70%), since pathogens become resistant to many antibiotics, antimicrobial agents used to treat inflammation of the lungs.

For whom, in the first place, is the danger of pneumonia? Is it contagious or not for others?
The following categories of people are most vulnerable to infection:

• Weakened people after operations
• People with severe chronic diseases
• People taking systemic hormonal drugs that depress immunity
• Pregnant women and women after childbirth
• People after SARS, flu, colds
• People who are in deep depression or in chronic stress
• Alcoholics, drug addicts

Is pneumonia still recoverable after recovery?

The disappearance of the symptoms of pneumonia and the normalization of X-ray results are not grounds for believing that there is no causative agent in the body. Medical institutions do not have any opportunities to determine this. Protecting from the effects of antibacterial drugs and immune defense of the body, bacteria are able to pass in L-form and such encapsulation of microbes allows them to exist for a long time in an unfavorable environment.

Once provoking factors appear to reduce immunity in adults, they safely begin to multiply, causing a relapse. In children, chronic inflammation of the lungs is extremely rare due to active blood supply, which prevents the development of bacterial encapsulation. However, in the presence of constant contact with the patient, which secretes bacteria, the risk of transition to a chronic disease significantly increases in the child.

Conclusion: Answering the question, pneumonia is contagious or not, it can be stated with certainty, pneumonia is contagious! Since there are still contagious forms of this disease, which are dangerous for people with weak immune response. And for today not many of us can boast of strong health, excellent immunity, healthy spirit in a healthy body. If you are in contact with a sick pneumonia, just in case observe the elementary rules of protection and safety, then the probability of infection will be minimal.

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.

Secret

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.

Inflammation of the lungs is contagious: the causes of the disease

This issue has worried everyone for a long time. Even the most experienced doctors can not give an unambiguous answer to the question: pneumonia - is it contagious? Maybe this article will help you figure it out?

Why there is pneumonia

Inflammation of the lungs involves an inflammatory process of the lung tissue.

Inflammatory pathogens:

1. chlamydia;

2. viruses (staphylococcus, pneumococcus, streptococcus);

Inflammation of the lungs - is it contagious?

In medical institutions (polyclinic, hospital, hospital) you can get pneumonia (hospital, hospital or nosocomial pneumonia). Such infection is unsafe for human health. Often, pneumonia occurs due to antibiotic resistant microbes: hemophilic rod, staphylococcus, streptococcus, pneumococcus, gram-negative bacilli, pneumohydamidosis. From a patient with pneumonia to a healthy person can be transmitted as a result of a close conversation, if the patient sneezes, coughs.

Inflammation of the lungs - causes of the disease

Causes of pneumonia can be:

1. severe hypothermia;

2. complications due to a viral infection: influenza, SARS;

3. weakening of human immunity;

4. stressful situations;

4. heavy physical activity;

5. overwork;

6. polluted air and others.

Danger of contracting pneumonia

Especially dangerous are purulent infections that are entered during the operation or postoperative period, which are almost impossible to cure. Community-acquired (home, outpatient) pneumonia, with all personal hygiene rules and with strong immunity, are very rare factors for infection. The main causative agent of such pneumonia can be pneumococcus and even less often - a stick of flu. This disease is easily treatable, except for single cases. Congenital pneumonia occurs as a result of intrauterine or hospital infection with staphylococcus, E. coli, herpes virus, streptococcus. Newborns can easily be infected with pneumonia. We can sum up and say that pneumonia itself is not contagious, but its pathogens may well infect a healthy person.

To prevent infection with lung disease, be careful with people who sneeze, cough. Try at the time of their sneezing or coughing to turn your head or close your mouth, so that the infection does not hit you through the airways to the lungs. Bacteria and viruses can be transmitted by contact. After shaking hands with patient pneumonia, always disinfect hands. According to some studies, pneumonia is contagious, so try to keep hygiene at work and at home.

Infect pneumonia from the dog

Answers:

Danial Axmetov

Airborne, pneumonia is not transmitted, unless, of course, it is not viral, not atypical. More often, pneumonia is caused by pyogenic microbes, but not by streptococcus viruses, staphylococcus, pneumococcus. It happens this way: first a person becomes infected with the flu or ARVI. These diseases are of viral origin and are transmitted by airborne droplets. The fight against the virus weakens the body, the immunity decreases, and to the viral, the bacterial infection, descending from the upper respiratory tract, to the lower, that is, to the bronchi and lung, causing bronchitis and pneumonia. And then, you can not do without antibiotics. As for viral, atypical pneumonia, it is called atypical because it is transmitted atypical for pneumonia, by air-drop, when the lungs are affected by the virus, with further, again, addition, bacterial flora. Such pneumonia, characterized by lightning current, severe intoxication, and poorly treatable.

Funnypepper

Even a person from a person can not get pneumonia, and even more so from a dog.

How is it transmitted

Answers:

Anna Matveeva

Pneumonia is an infectious disease, but it is caused by various microbes. Most often these are microbes from the nasopharynx, which, during a viral infection, aspirate into the bronchi. In principle, you can get infected from a patient with pneumonia, but not the fact that it is pneumonia, it can be pharyngitis, bronchitis, and sinusitis. But infectiousness is not high.

4eburator

Of course not

Vitaliy

Pneumonia-noninfectious disease

Lana

Maybe call an ambulance and ask... or polyclinic ...

Galina Firsova

Pneumonia. Infectious process in the lungs, arising either as an independent disease, or as a complication of other diseases. Pneumonia is not transmitted from person to person, it is caused by various bacteria and viruses. Development is facilitated by unfavorable conditions - severe hypothermia, significant physical and neuro-psychological overload, intoxication and other factors that reduce the resistance of the body, which can lead to activation of the microbial in the upper respiratory tract flora.

Tanya

You can be calm - pneumonia through kisses is not exactly transmitted !!!

A.G.

if the complicated form is yes!

Mystery

This is just a neglected cold, or ARVI or the flu can give it. By itself, the consequences of pneumonia

Artem Yurinov

No, not transmitted

Just Kseniya

If the family has a patient with pneumonia, then they check the whole family.
Pneumonia causes bacterium pneumocystis.
