How Covid-19 Affect the body organs during and after the Infection
There are many types of coronaviruses. Some give you the common cold. The new coronavirus behind
the 2019-2021 pandemic causes an illness called COVID-19.
How Does Coronavirus Attack Your Body?
A virus infects your body by entering and attacking healthy cells. There, the virus makes copies of itself
and multiplies throughout your body.
The new coronavirus attatches its spiky surface proteins to receptors on healthy cells, especially those in
your lungs.
Specifically, the viral proteins bust into cells through ACE2 receptors. Once inside, the virus attacks
healthy cells and takes command. Eventually, it kills a number of the healthy cells lowering the immunity.
How Does Coronavirus Move Through Your Body?
COVID-19, the illness caused by the coronavirus, sprads through droplets from an infected person’s
cough, sneeze, or breath. They could be within the air or on a surface that you simply touch before
touching your eyes, nose, or mouth. That gives the virus a passage to the mucous membranes in your
throat. Within 2 to 14 days, your system may respond with symptoms including:
Fever
A cough
Shortness of breath or trouble breathing
Fatigue
Chills, sometimes with shaking
Body aches
Headache
A sore throat
Congestion or a runny nose
Loss of taste
Loss of smell
Nausea or vomiting
Diarrhea
The virus moves down your respiratory tract. That’s the airway that has your mouth, nose, throat, and
lungs. Your lower airways have more ACE2 receptors than the remainder of your tract . So COVID-19 is
more likely to travel deeper than viruses just like the cold .
Your lungs might become inflamed, making it difficult for you to breathe well. This can cause pneumonia,
an infection of the small air sacs (called alveoli) inside your lungs where your blood exchanges oxygen
and CO2 .
If your doctor does a CT scan of your chest, they’ll probably see shadows or patchy areas called
“ground-glass opacity.”
For many people, the symptoms end with a cough and a fever. More than 8 in 10 cases are mild. But for
some, the infection gets more severe. About 5 to eight days after symptoms begin, they have shortness
of breath (known as dyspnea). Acute respiratory distress syndrome (ARDS) begins a couple of of days
later.
