Is pneumonia contagious - looking for the answer to an important question
Whether pneumonia is contagious has been heated for a long time, because until recently it was considered safe for contact. But recently it was confirmed that it is still possible to become infected with it.
In 1994, large-scale studies were conducted in the United States, during which scientists found not only that pneumonia ranks fourth among the diseases that caused death, the most unexpected was that in the pulmonology departments, up to 36% of the personnel became ill with it every year and more than once.
In addition, cases of pneumonia epidemics have increased. As you understand, with a non-contagious disease like this would be impossible.
What can be caused by pneumonia
First of all, it is necessary to figure out how to get pneumonia. Most often this occurs against the background of an existing acute respiratory viral infection, which greatly reduces the immunity of the sick person - this is where a bacterial or other infection joins the existing problem.In this case, the pathogens that lead to pneumonia may be very different:
- pathogenic fungi;
- the simplest;
Any of them, getting into the respiratory tract, quickly spreads to the lungs, while violating the protective function of epithelial tissue. And their further rapid reproduction causes the appearance of foci of inflammation.
Each type of pathogens requires its own antibiotic, which is why it is so important to determine which microbial species caused the disease.
Is it possible to attribute to infectious bacterial pneumonia
As you probably already understood, 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 types of various pneumonia are known. And only depending on the causative agent of the disease, one can speculate whether pneumonia is contagious.
Thus, bacterial inflammation of the lungs occurs when infected with bacteria 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 to be in contact with him, but it can provoke an infection of the upper respiratory tract, for example.That is, a healthy person who has communicated with a patient with pneumonia may get sick, but it does not necessarily turn out to be pneumonia.
Whether pneumonia is caused by mycoplasma
But if atypical representatives of microorganisms, such as mycoplasma or chlamydia, become the causative agents of the disease, then most often they are transmitted by airborne droplets. Therefore, knowing that your friend or relative is sick with one of these types of pneumonia, exclude or minimize contact with him. As in this case, a healthy person has a high risk of infection.
What pneumonia is especially contagious
Answering the question of whether pneumonia is contagious to others, it is worth noting that it primarily affects those people who have weakened immunity.
The most dangerous in this sense is that pneumonia, which was picked up in a medical institution, because in this case the disease is provoked by bacteria already resistant to antibiotics: pneumococcus, hemophilus bacilli, gram-negative bacilli, pneumoclamydiosis and staphylococcus.
By the way, the most dangerous is infection with pyogenic flora, since it is almost not treatable.
The main signs of pneumonia
Is pneumonia of community origin contagious? Its pathogens are most often pneumococci and influenza bacilli. And this type of disease is generally considered safe for others, but subject to strong immunity and their personal hygiene.
True, in our time it is impossible to be 100% sure in the strength of one’s own immunity, and therefore it is unacceptable to miss the signs of pneumonia. The most obvious symptoms include:
- persistent strong cough;
- the deterioration of the cold, which has lasted for more than a week;
- chest pains that do not allow to take a deep breath and cause a coughing fit;
- pallor, fever;
- shortness of breath when walking and during a temperature increase;
- its spasmodic increase and weak effect on the temperature of antipyretic agents.
If at least some of the symptoms are present, the patient should undergo a mandatory examination for the presence of pneumonia.
Pneumonia that is not contagious
Is it possible to get pneumonia if its appearance is triggered by the inhalation of mercury vapor, acids, toxic chemicals or carbon monoxide?
This type of pneumonia is rare, and it mainly affects people who work in hazardous industries. Harmful substances in large quantities into the lungs, causing damage and cell death. And this, in turn, entails manifestations of the inflammatory process: worsening of well-being, cough, debilitating fever, chills and nausea.
But, despite all the signs, chemical pneumonia is not infectious.
A few more words about whether pneumonia is contagious to others
Summing up, it should be noted that pneumonia itself is not contagious, which cannot be said about its pathogens, which can cause the development of pneumonia in other people.
So, arguing whether pneumonia of the lungs is contagious, it must be borne in mind that in most cases it is not infected, but gets sick. However, in order for this to happen, a person must, as already mentioned, have a weakened immunity, and if this is accompanied by a lack of vitamins, stress, hypothermia, or exposure to the influenza virus, the effect of pneumococcus, which most often stimulates the development of pneumonia, becomes dangerous to health. and causes illness.
