Is mild pneumonia contagious

summary

Pneumonia refers to inflammation of the terminal airway, alveoli and lung interstitium. Its symptoms: fever, shortness of breath, persistent dry cough, may have unilateral chest pain, deep breathing and cough chest pain, a small amount of phlegm or a large amount of phlegm, may contain blood. Children with pneumonia, symptoms are often not obvious, may have a slight cough or no cough at all. Attention should be paid to timely treatment. Is mild pneumonia contagious? Let's talk about it.

Is mild pneumonia contagious

First, Streptococcus pneumoniae is the most common bacterial infection in adult pneumonia. Other pathogens include anaerobes, Staphylococcus aureus, Haemophilus influenzae, Chlamydia pneumoniae, Chlamydia psittaci, Chlamydia trachomatis and other gram-negative bacilli. These pathogens may be transmitted through the contact between people, or through the contact between people and objects, but even if infected with these pathogens, as long as their own immunity is sound, they will not get pneumonia. It is often when the body's resistance decreases that pathogens will take advantage of the situation and make people sick.

Second, there are relatively few infectious pneumonia, such as SARS, anthrax, and pneumonic plague. This kind of pneumonia is caused by viruses and is highly infectious. It is a kind of infectious disease strictly controlled by the state. Of course, there is no need to be particularly afraid of this kind of disease. Although it is very dangerous, the possibility of getting sick is also very small. The pathogenesis, pathogenesis and treatment of these diseases are different from pneumonia.

Third: pneumonia is mostly caused by pneumococcal infection of lung parenchyma inflammation. Hair coloring incidence of pneumococcal infection is related to age, showing a "U" curve, which means the incidence rate of both is higher. This feature is particularly noticeable in severe pneumococcal infections, such as pneumonia and bacteremia. Although the overall incidence rate of pneumococcal disease is lower than that of the previous antibiotic era, the incidence rate of "U" type has not changed. This shows that infants and the elderly are still the most susceptible group of pneumococcal diseases. Other risk groups include patients with chronic diseases and low immune function.

matters needing attention

Pneumonia is a kind of multiple and serious infectious disease. If the condition is delayed, it may cause pneumonia with heart failure, pneumonia with encephalitis, and even cause lung abscess or death.
