There are numerous versions of coronaviruses. Some simply cause the common cold. The newly appeared coronavirus, however, causes a sickness named COVID-19. And while there’s a lot of info regarding what precautions one should take as to avoid contamination, there’s not as much talk about what actually happens inside the body once the virus gets in.
In What Way Does the Coronavirus Attack Your Body?
Viruses infect living beings by penetrating healthy cells. When this occurs, the invader creates as many copies of itself as possible in order to spread throughout your body. The currently active coronavirus latches itself with its spiky surface proteins to the receptors of the healthy cells. To be more precise, these viral proteins get into cells through ACE2 receptors. If they manage to get inside, the virus tries to take command over the healthy cells. In fact, it even kills a certain portion of these cells.
In What Unique Way Does the Coronavirus Move Through One’s Body?
This particular strain of the coronavirus variety has both some common and some unique traits. The common thing is that it all begins with droplets from an infected person’s cough, sneeze, or even breath. These droplets could linger in the air or be present on a surface that you touch. If you touch a contaminated surface, the virus can enter your body when you touch your eyes, nose, or mouth. This is how the virus particles find their way to the mucous membranes that reside in one’s throat. After that, within a period of 14 days, your immune system may or may not respond with symptoms in the form of a sore throat, a fever, or a dry cough.
Then, the intention of the virus is to move down your respiratory tract. This encompasses the airway that includes your mouth, nose, throat, and lungs. The lower airways of the human body have more ACE2 receptors than the rest of the tract. That being said, it’s no surprise that COVID-19 is more likely to go deeper than viruses like the common cold – this is simply how it works.
If the immune system of the person is compromised and there’s no way to go through this with mild or no symptoms, the lungs might become inflamed, which is likely to make it tough for the infected person to breathe. All of this can lead to further complications in the form of pneumonia, which is an infection that attacks the tiny air sacs (alveoli) inside the lungs where the blood exchanges oxygen and carbon dioxide. If a doctor does a CT scan of an infected person’s chest, they’ll probably find shadows or patchy areas that go by the name “ground-glass opacity.”
Luckily, for most people, nothing more than the mild symptoms occur – it all ends with a cough and a fever. In fact, it has been estimated that more than 8 in 10 cases are mild. For some people, however, the infection gets more severe. Within a period of 5 to 8 days after the symptoms start, they experience shortness of breath (dyspnea). Acute respiratory distress syndrome (ARDS) follows several days later.
ARDS can cause rapid breathing, a fast heart rate, dizziness, and sweating. It damages the tissues and blood vessels in your alveoli, causing debris to collect inside them. This makes it harder or even impossible for you to breathe.
The state of ARDS can result in rapid breathing, quickened heart rate, dizziness, and sweating. It is likely to damage the tissues and blood vessels in one’s alveoli, thus opening the opportunity for debris to collect inside them. This can render it hard or even impossible for the person to breathe.
