Pneumonia is contagious or not? This question interests many people, surrounded by a person with characteristic symptoms of pathology.. In most cases, pneumonia is an infectious disease. In general, the disease itself is not contagious, but the infection that caused the development of the inflammatory process can be transmitted from person to person, according to Pannochka, an Internet publication for girls and women from 14 to 35 years old.. net The causative agent of pneumonia can be transmitted in different ways, including. Pneumonia is a disease in which inflammation affects the lung tissue. Depending on its location, it can be right-sided, left-sided or bilateral.
Pneumonia is a fairly common disease. Every year, about 450 million people on the planet suffer from pneumonia, while approximately 7 million die from this disease..
The infectiousness of the pathology depends on several factors:.
form of the disease;
causative agent;
the state of the human immune system.
Such forms of pneumonia as congestive (in bedridden patients), autoimmune and allergic, cannot be transmitted to another person.
Disease Pathogens Pneumonia can be caused by bacteria, viruses or fungi.. The most serious forms of pneumonia are caused by a bacterial infection that can enter the lung tissue from the outside or through the bloodstream from other foci of inflammation.
Pneumonia often develops as a complication of colds caused by influenza, herpes, or coronaviruses.
Pneumococci In almost 80% of cases, these pathogenic microorganisms become the causative agents of pneumonia.. Most often, they provoke acute forms of the disease with respiratory manifestations in the form of a runny nose, choking, high fever. They enter the human body in different ways and do not always lead to the development of the disease..
Streptococci Streptococcal pneumonia is less common than pneumococcal pneumonia, and its course is not so severe. Bacteria are transmitted from person to person in different ways, they can live in the body for a long time without leading to serious diseases.
In most cases, bacteria lead to the development of pathology - streptococci, pneumococci, staphylococci Most often, streptococcus causes the development of tonsillitis. But sometimes, when immunity is weakened, these bacteria lead to pneumonia.. Strep pneumonia can also be a complication of colds.
Staphylococcus In rare cases, the causative agent of pneumonia is staphylococcus (hemolytic, aureus). These bacteria are conditionally pathogenic microorganisms, they live on the mucous membranes of the mouth, stomach, intestines and genitals.
With a decrease in immunity, bacteria can form large conglomerates, with reduced sensitivity to therapy. Staphylococcus bacteria can enter the human body in any way.
Klebsiella There are many varieties of these enterobacteria. They are classified as conditionally pathogenic microorganisms that reveal their pathogenic qualities only under certain conditions.. The most dangerous are:.
Type of bacteria.
Features of the course of the disease.
Klebsiella pneumoniae (Friedlander's bacillus, Klebsiella pneumoniae).
Children are most susceptible to its effects. Most often, this type of bacteria provokes intestinal disorders, but in some cases it causes pneumonia with severe enough symptoms..
Klebsiella oxytoca (klebsiella oxytoca).
In rare cases, causes a sluggish form of pneumonia with mild symptoms.
Klebsiella ozaenae (klebsiella ozenes).
In most cases, it provokes a fetid rhinitis, but with a weakened immunity, it can lead to the development of generalized forms of pneumonia with pronounced symptoms from the gastrointestinal or genitourinary tract.
Chlamydia Atypical pneumonia can be caused by bacteria from the genus Chlamydia:.
Type of bacteria.
Features of the course of the disease.
Chlamydophila pneumoniae (chlamydia pneumoniae).
These microorganisms cause sluggish pneumonia.. The disease is not so dangerous, but quickly becomes chronic and often worsens.
Chlamydia trachomatis.
Causes very severe disease, sometimes fatal.
Chlamydia psittaci.
Causes severe, difficult-to-treat pneumonia.
Viruses Influenza viruses, parainfluenza, adenoviruses, measles virus can become the causative agent of pneumonia.. Initially, the disease begins with symptoms of a cold, and then symptoms characteristic of pneumonia appear..
Viruses are among the possible causative agents of pneumonia. Often, the viral form of the disease is complicated by the addition of a bacterial infection..
