How does Corona invade the lungs and what does it do to them?

The “Covid 19” affliction began in late 2019 when cases of pneumonia appeared in China for an unknown reason.

Later on, the cause of pneumonia is known, which is a new virus, whose scientific name is “SARS Cove 2”, or severe acute respiratory syndrome 2, or “Covid 19” according to the WHO designation, which is the disease caused by the Coronavirus.

Although the organization has declared a newly emerging epidemic of coronavirus, “Covid 19” may be mild to the majority of people who contract it, specialists say.

Slight illness

8 out of 10 people develop slight symptoms of the Coronavirus, and the main symptoms are high temperature and coughing, in addition to body aches, sore throat, and headache, but they are possible symptoms and not a sure sign of infection and can be treated with bed rest, a lot of fluids and paracetamol, while The patient needs hospital care.

But some people will develop more serious symptoms of Covid 19.

How can he invade the lung?

Coronavirus enters the body when inhaled by the respiratory system, when a nearby person coughs or on contact with a contaminated surface and then touches the face.

During the incubation period, the virus consolidates its presence in the body, enters the cells that make up the body and then takes over it.

The incubation period, which is the period between infection with the virus and the onset of symptoms, varies greatly from person to person, but on average it may be up to 14 days.

The virus first affects the lining cells of the throat, trachea, and lung, in order to cause them to produce massive amounts of other viruses that infect more cells.

The critical stage

the severity of the disease is caused by the body taking an excessive response to the virus.

Professor John Wilson, President of the Australian Royal College of Physicians and Respiratory Doctor for the British newspaper “The Guardian”, says that the virus causes an immune response, as the body develops pneumonia (pneumonia).

It is possible to transfer through the mouth to the trachea and lung, the virus will reach the small alveoli through which oxygen is transferred to the blood, and carbon dioxide to the outside.

But in the case of pneumonia, the alveoli begin to fill with water, which may cause shortness of breath and difficulty, and some may need a device for respiration.
