How our body reacts when infected with Covid-19?
"They seek cells of different organs such as lungs, heart, and liver among others."
When the virus gets inside our body through droplets from an infected person’s cough, sneeze, or breath it gets inside our body cells and hijacks them.
It first infects the cells lining your throat airways and lungs and turns them into “coronavirus factories” that spew out huge numbers of new viruses that go on to infect yet more cells.
Viruses are small pieces of RNA (ribonucleic acid) or DNA (deoxyribonucleic acid).
They are wrapped up in a layer of protein, which acts as a protective layer for genetic material.
“If the virus enters through your nose, you may notice typical symptoms of upper respiratory tract infection, such as a runny nose or congestion,” says Dr. Patel.
“The virus may stop there or may continue down the respiratory tract, where it can cause issues such as coughing.”
When our body spots the virus our immune system counterattacks.
One sign of that is a fever, this virus infects our body by entering healthy cells the coronavirus latches its spiky surface protein to receptors on healthy cells, especially those in our lungs, and eventually, it kills some of the healthy cells.
When the coronavirus enters our body it first binds to the two cells in our lungs, namely- goblet cells that produce mucus and cilia cells which have hairs on them.
The function of these cells is to keep our lungs safe from outside dust and pollution.
They normally prevent our lungs from filling up with debris and fluids such as viruses and bacteria and particles of dust and pollen.
Once, such viruses are attached to live cells, they enter and depending on their type.
They seek cells of different organs such as lungs, heart, and liver among others.
If the body’s immune system is strong the virus can’t do much harm.
Otherwise, the harm caused by viruses is severe, sometimes fatal.
When you first become infected, your body launches its standard innate immune defense like it would for any virus.
This involves the release of proteins called interferons that interfere with the virus’s ability to replicate inside the body cells.
The infection can then reach the lungs causing inflammation in the mucous membranes and damaging our air sacs.
The inflammation hampers the lung’s ability to oxygenate the blood and remove carbon dioxide from the bloodstream.
The virus can also enter the bloodstream and may be able to infect the gastrointestinal system, causing symptoms like diarrhea and indigestion.
Scientists are still perplexed by the novel coronavirus.
But it’s becoming clear increasingly clear that the immune system plays a critical role in whether you recover from the virus or you die from it.
For now, your best defense against the virus is to support your immune system with sleep, exercise, and good nutrition and, most importantly to wash your hands and practice social distancing so you don’t get infected in the first place.
