Author:SARS-CoV-2 does much more damage to the human body than initially assumed. It can attack any number of organs and even penetrates the brain. But why do some people experience worse symptoms than others?
The pathogen has already done a fair bit of damage. It has only been five days since the patient began exhibiting typical COVID-19 symptoms, but already, menacing shadows can be seen in the CT scans of the lungs.

It is a phenomenon he has been seeing frequently in recent weeks and it is caused by the novel coronavirus, SARS-CoV-2. The number of confirmed COVID-19 patients worldwide is now well over 4.2 million and the number of deaths is approaching 300,000. Meanwhile, doctors and biologists are doing all they can to gain a better understanding of the pathogen behind the pandemic.
