What is COVID-19? How does COVID-19 spread?

What is COVID-19? however, does. This is severe acute respiratory syndrome CoV-2 It belongs to the family of coronaviruses, named for crownlike spikes on their surfaces. severe acute respiratory syndrome CoV-2 will cause COVID-19, a contagious infection that attacks primarily your throat and lungs.

How will COVID-19 spread?
What truly happens in your body once you contract the coronavirus?
What specifically causes your body to develop pneumonia?
How would an immunogen work?

The COVID-19 is AN communicable disease caused by severe acute metabolism syndrome coronavirus ( severe acute respiratory syndrome ).

                 The coronavirus should infect living cells so as to breed. Let's have a better regarding it’s. within the virus, genetic material contains the data to create additional copies of itself. A macromolecule shell provides a hard-protective enclosure for the genetic material because the virus travels between the individuals it infects. AN outer envelope permits the virus to infect cells by merging with the cell's outer membrane. protrusive from the envelope area unit spikes of macromolecule molecules. each a typical contagious disease virus and therefore the new coronavirus use their spikes sort of a key to inducing within a cell in your body, wherever it takes over its internal machinery, repurposing it to create the parts of latest viruses. once AN infected person talks, coughs or sneezes, droplets carrying the virus might land in your mouth or nose so get in your lungs. Once within your body, the virus comes into contact with cells in your throat, nose or lungs. One spike on the virus inserts into a receptor molecule on your healthy cell membranelike a key in a very lock. This action permits the virus to induce within your cell. A typical contagious disease virus would travel within a sack made up of your cell wall to your cell’s nucleus that wherever your cell homes all its genetic material. The coronavirus, on the opposite hand, doesn’t get to enter the host carryon. It will directly access components of the host cell, known as Ribosomes. Ribosomes use genetic info from the virus to create microorganism proteins, like the spikes on the virus’ surface.

                 A packaging structure in your cell then carries the spikes in vesicles, that merge along with your cell' Souter layer, the cell wall. All the components required to make a brand-new virus gather simply at a lower place your cell's membrane. Then a brand-new virus begins to butt far away from the cell's membrane. For this, we’ll examine your lungs. every respiratory organ has separate sections, known as lobes. Normally, as you breathe, air moves freely through your trachea, or cartilaginous tube, then through massive tubes, known as bronchi, through smaller tubes, known as bronchioles, and eventually into small sacs, known as alveoli. Your airways and alveoli area unit is versatile and whippy. once you respire, every air sac inflates sort of a tiny balloon. And once you exhale, the sacs deflate. tiny blood vessels, known as capillaries, surround your alveoli. atomic number 8 from the air you breathe passes into your capillaries, then CO2 from your body passes out of your capillaries into your alveoli in order that your lungs will get obviate it once you exhale. Your airways catch most germs within the mucous secretion that lines your trachea, bronchi, and bronchioles. in a very healthy body, hair-like cilia lining the tubes perpetually push the mucous secretion and germs out of your airways, wherever you'll expel them by coughing. Normally, cells of your system attack viruses and germs that create it past your mucous secretion and cilia and enter your alveoli. However, if your system is weakened like within the case of coronavirus infection, the virus will overwhelm your immune cells and your bronchioles and alveoli become inflamed your system attacks the multiplying viruses. The inflammation will cause your alveoli to fill with fluid, creating it troublesome for your body to induce the atomic number 8 it desires. you may develop pneumonia, wherever one lobe of your lungs is affected, otherwise, you might have bronchial pneumonia that affects several areas of each lung. the respiratory disease might cause issue respiration hurting coughing, fever and chills, confusion, headache, muscle pain and fatigue. It also can result in additional serious complications: metabolism failure happens once your respiration becomes thus troublesome that you simply would like a machine known as a ventilator to assist you to breathe. These area units the machines that save lives and medical device corporations presently increase production for. whether or not you'd develop these symptoms depends on loads of things, like your age And whether or not you have already got an existing condition. whereas all this all sounds shivery, the push to develop a coronavirus immunogen is moving at high speed. Studies of alternative coronaviruses lead most researchers to assume that folks World Health Organization have recovered from a SARS-CoV-2 infection may be shielded from reinfection for an amount of your time. however, that assumption must be backed by empirical proof and a few studies recommend otherwise. There area unit many totally different approaches for a possible immunogen against the coronavirus. the essential plan is that you simply would get an endeavour that contains faint versions of the virus. The immunogen would expose your body to the virus that's too weak to cause infection however simply robust enough to stimulate AN immune reaction. at intervals, a couple of weeks, cells in your system would create markers known as antibodies, which might be specific for less than the coronavirus or specifically its spike macromolecule. Antibodies then attach to the virus and forestall it from attaching to your cells. Your system then responds to signals from the antibodies by overwhelming and destroying the clumps of viruses.

                 If you then catch the real virus at a later stage, your body would recognize and destroy it. In other words, your immune system is now primed. Collecting evidence on whether this will be possible, safe and effective is part of what’s taking researchers so long to develop a vaccine. It is a race against time to develop a vaccine amid a pandemic. Each step-in vaccine development usually takes months if not years. An Ebola vaccine broke records by being ready in five years. The hope here is to develop one for the new coronavirus in a record-breaking 12 to 18 months. While all this will take time, stay home if you can to protect the most vulnerable and don’t forget to wash your hands for at least 20 seconds and as often as possible.
