Coronavirus Infection: How Does It Affect The Body?
A virus enters the body through healthy cells and infects them. The invader multiplies in your body by making copies of itself.
The new coronavirus attaches itself to receptors on healthy cells, especially those in your lungs, with its spiky surface proteins.
The viral proteins specifically enter cells via ACE2 receptors. Once inside, the coronavirus seizes control of healthy cells. Any of the healthy cells are eventually killed.
Coronavirus: How Does It Move Around The Body?
COVID-19 is a coronavirus-related illness that begins with droplets from an infected person's cough, sneeze, or breath. They may be in the air or on a surface you touch before putting your hands to your eyes, nose, or mouth. This allows the virus to enter your throat through your mucous membranes.
Your immune system can respond in 2 to 14 days with symptoms such as:
Shortness of breath or trouble breathing
Chills, sometimes with shaking
A sore throat
Congestion or a runny nose
Loss of taste
Loss of smell
Nausea or vomiting
The virus spreads from your upper respiratory tract to your lower respiratory tract. Your mouth, nose, throat, and lungs are all part of your airway.The ACE2 receptors in your lower airways are more numerous than those in the rest of your respiratory tract. As a result, COVID-19 is more likely to penetrate the body than viruses such as the common cold.
It's possible that the lungs could become inflamed, making breathing difficult. This may result in pneumonia, an inflammation of the tiny air sacs (called alveoli) that exchange oxygen and carbon dioxide in your lungs.
A CT scan of your chest would most likely reveal shadows or patchy areas known as "ground-glass opacity."
The majority of people's signs include a cough and a fever. More than eight out of ten cases are minor. However, for some people, the infection becomes more severe. They experience shortness of breath 5 to 8 days after the onset of symptoms (known as dyspnea). After a few days, the patient develops acute respiratory distress syndrome (ARDS).
Rapid breathing, a high heart rate, dizziness, and sweating are all symptoms of ARDS. Many people with ARDS need the assistance of a ventilator to breathe.
As fluid builds up in your lungs, the oxygen carried to your blood decreases. That means your blood may not be supplying enough oxygen to your organs to keep them alive. Your kidneys, lungs, and liver can shut down and stop working as a result of this.
What Does COVID-19 Do to The Body Apart From That?
Some people also have symptoms including:
r problems or damage
Blood clots in their legs, lungs, and arteries are very dangerous. Some clots may cause a stroke.
Reports of mouth sores and skin rashes, including reddish-purple spots on fingers and toes, are being investigated by researchers.
So, if you can, stay at home and wash your hands as much as possible.
