If there is phlegm in the corridor, will it spread pneumonia?

Pneumonia refers to an inflammatory disease of the lung tissue. In general, phlegm in the hallway may spread pneumonia.

1. Contagious conditions

Pneumonia is usually caused by a bacterial infection and is contagious and can be transmitted by droplets. If the patient does not take precautions when coughing or sneezing, and is in a confined space for a long time, it will cause pathogens in the respiratory tract to enter the air in the form of droplets, and cross-infection will occur after contact.Therefore, when someone coughs or sneezes in the corridor, you should stay away and wear a mask in time to avoid getting infected.

2. Non-contagious conditions

1. Novel coronavirus infection: If pneumonia is caused by the new coronavirus, there will be no contagion. Because the currently circulating new coronavirus variant is Omicron, its virulence has been greatly weakened, and most people who have been vaccinated with the new coronavirus vaccine will produce corresponding antibodies in the body, which can play a role in resisting the virus, thereby reducing the probability of disease.

2. Bronchitis: If the bronchial mucosa is damaged due to factors such as long-term smoking, alcoholism, etc., the disease will also be induced, but it is not an infectious disease, so it will not cause infection.

3. Chronic obstructive pulmonary disease: usually related to genetic factors and environmental factors, symptoms such as dyspnea and chest tightness will occur after the disease, but it is not an infectious disease, so it will not be transmitted to others.

4. Pulmonary tuberculosis: It is mainly caused by Mycobacterium tuberculosis infection, which is a certain infectious disease, which can be caused by inhalation of droplets in the air through the mouth and nose, and can also invade the human body through skin wounds.

5. Lung abscess: refers to the accumulation of a large amount of pus in the alveolar cavity due to various reasons, which is mainly manifested as high fever, coughing up a large amount of pus-smelling sputum and other uncomfortable symptoms, and is not infectious.

Patients are advised to seek medical treatment in time to avoid exacerbation of the condition. Pay attention to indoor ventilation in daily life, wear a mask when going out, and avoid going to crowded places.
