Pneumonia is an acute infectious disease of the lungs, or
just pneumonia. The incidence of pneumonia among
population of the planet is striking in its numbers every year only in Russia
registered over 2 million cases of the development of this disease.
Considering pneumonia as the cause of death

give a definite answer. To understand this question should
consider what types of pneumonia exist:
- Community-acquired pneumonia
If we consider pneumonia from the point of view of the pathogen
disease, then bacterial, common pneumonia, medicine
recognized as a non-infectious form of inflammation. In most cases
pneumonia is a complication of acute respiratory viral infection, parainfluenza, influenza,
rhinovirus, especially in children. If the virus caused the inflammatory

accumulation of mucus, pus. This complicates the ventilation of the lungs and leads
to the accumulation of bacteria.
And naturally when coughing, sneezing,
in a loud conversation the patient emits a pathogen of pneumonia into the air.
If a person has pneumonia caused by a virus, then
contamination of others is possible by airborne droplets, but only
the root cause of the disease, that is – ARVI or flu. But
Whether pneumonia develops in infected individuals depends directly on the protective

- Dangerous, infectious types of pneumonia
If the causative agent is tuberculosis (caseous pneumonia) or
atypical representatives such as chlamydia, mycoplasma, SARS (species
atypical pneumonia, which is called – severe acute
respiratory syndrome), these forms of pneumonia are transmitted
from person to person by airborne droplets. The good news is that these
types of disease rarely cause epidemics and are found in single
cases. If a person is in contact with such a patient, weakened
immunity, the likelihood of infection by such dangerous forms
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
Investigations in the USA for infection
health workers serving in the pulmonary departments
found that employees of these departments suffer diseases
respiratory organs more often than other citizens of the country. Namely,
the incidence of medics of pulmonology was over 35% for
year. That is, the medical staff of these departments has a high risk
hospital pneumonia, and many of the workers suffered
pneumonia even a few times. Causative agents of hospital pneumonia
are often gram-negative bacteria, anaerobes, chlamydia,
staphylococcus, streptococcus. It is hospital pneumonia that is
the cause of high mortality from this disease (almost 70%),
because pathogens become resistant to many
antibiotics, antimicrobial agents used to treat
For whom is the danger of pneumonia first?
Is it contagious or not to others? Most vulnerable to infection

- Weakened people after surgery
- People with severe chronic illnesses
- People taking systemic hormonal drugs that

- People after SARS, flu, colds
- People who are in deep depression or in chronic
- Alcoholics, drug addicts

Вывод: Отвечая на вопрос, пневмония заразна или
no, it’s safe to say pneumonia is contagious!
Since there are still contagious forms of this disease,
which are dangerous for people with weak immune response. And on
today not many of us can boast of strong
health, excellent immunity, healthy mind in a healthy body.
If you are in contact with a patient with pneumonia, just in
case follow the elementary rules of protection and safety, then
the probability of infection will be minimal.
