It was generally agreed that the main “target” of coronavirus infection is the human lungs. According to the virologist William Schaffner, other processes occur in the human body during infection.
A specialist from the Vanderbilt University Medical Center recalled that a coronavirus infection spreads when particles are sprayed that a sick person “sprays” around him when sneezing or coughing. These particles enter the eyes, as well as the mucous membranes of the mouth and nose. In addition, they can settle on clothing or other surfaces, writes Nation news.
Schaeffner explained that once in the human body, coronavirus cells immediately go to the respiratory tract, from where they already go to the lungs. And already here, having fixed itself to the epithelial tissue, the virus begins to multiply very quickly. And this process continues until all lung cells are “occupied” by copies of the virus.
The most common symptoms of COVID-19 are known to be dry cough, headache, and fever. Due to the fact that after infection, damage to the alveoli occurs, pulmonary edema begins, and then the inflammatory process begins.
After that, oxygen ceases to flow into this respiratory organ. Due to the inflammatory process, the lungs gradually fill up with pus and fluid. A similar complication is bacterial pneumonia.
An even more serious complication, which threatens the patient with a fatal outcome, is an acute respiratory distress syndrome, characterized by diffuse infiltration and severe hypoxemia. In this case, the patient already needs to be connected to a ventilator.
Disruption of the respiratory system is not the only complication caused by coronavirus infection.
“Viral particles can infect the cells of the mucous membranes of many organs, especially the gastrointestinal tract,” concluded William Schafner.
