Corona virus how does it spread / symptoms of corona virus.

coronaviruses

This is sars-cov-2, it belongs to the family of coronaviruses named for the crown, like spikes on their surfaces, sars-cov-2 can cause COVID-19 a contagious viral infection that attacks primarily your throat and lungs. What will actually happen in your body when your body contracts the coronavirus? What happens in your body that causes your body to develop pneumonia and how would a vaccine work?

What will actually happen in your body when your body contracts the coronavirus?

The coronavirus must infect living cells in order to reproduce, let's have a closer look inside the virus. Genetic material contains the information to make more copies of itself. A protein shell gives a hard protective enclosure for the genetic material as the virus travels between the people it infects, an outer envelope allows the virus to infect cells by merging with the cells outer membrane. Not touching from the envelope are spikes of protein molecules. Both a typical influenza virus and the new coronavirus use their spikes like a key to get inside a cell in your body, where it takes over the cells internal machinery, repurposing it to build the components of new viruses.

When an infected who is infected by virus person talks, coughs or sneezes, droplets coming out from his mouth carrying the virus may land in your mouth or nose and then move into your lungs. Once inside your body, the virus comes in contact with cells in your throat, nose or lungs. One spike on the virus goes into a receptor molecule on your healthy cell membrane like a key in a lock, this will allow the virus to get inside your cell. A typical flu virus would travel into a sac made from your cell membrane to your cell's nucleus that stores all its genetic material.

What happens when virus goes inside your body.

The coronavirus, on the other hand, doesn't need to enter the host cell nucleus. It can direct allow parts of the host cell called ribosomes. Ribosomes use genetic information from the virus to make viral proteins such as the spikes on the virus a surface. A packaging structure in your cell then carries the spikes in vessels which merged with your cells, outer layer, the cell membrane, all the parts needed to create a new virus gathered just beneath your cells membrane.

Then a new virus begins to be cut off from the cells membrane. Now, with the virus spreading in your body, how can you develop pneumonia symptoms for this?

We'll have to look into your lungs. Each lung has separate sections called lobes. Normally, as you breathe, air moves freely through your trachea or windpipe, then through large tubes called bronchi through smaller tubes called bronchioles and finally into tiny sacs called alveoli. Your airways and alveoli are flexible and springy. When you inhale in each air, sac inflates like a small balloon. And when you exhale, the sacs deflate. Small blood vessels called capillaries surround your alveoli and make you sick.

The oxygen you inhale from the air passes into your capillaries, and then carbon dioxide from your body passes out of your capillaries into your alveoli so that your lungs can get rid of it. When you exhale, your airways attract most germs in the mucus that lies in your trachea, bronchi and bronchioles in a healthy body. Hair-like cilia lining the tubes constantly push the mucus and germs out of your airways where you might expel them by coughing. Normally, cells of your immune system attack viruses and germs that make it past your mucus and cilia and enter your alveoli.

However, if your immune system is weakened, like in the case of coronavirus infection, the virus can overwhelm your immune cells and your bronchioles and alveoli become inflamed as your immune system attacks the multiplying viruses.

The inflammation can cause your alveoli to fill with fluid, making it difficult for your body to get the oxygen it needs. You could develop lobar pneumonia where one lobe of your lungs is affected, or you could have bronchopneumonia that affects many areas of both lungs. Pneumonia may cause difficulty breathing, chest pain, coughing, fever and chills, confusion, headache, muscle pain and fatigue. It can also lead to more serious complications. Respiratory failure occurs when your breathing becomes so hard that you need a machine called a ventilator which helps you breathe.

These are the machines that help in saving lives and those medical device companies currently high up production for.

symptoms of coronavirus.

Whenever you would develop these symptoms depends on a lot of factors like your age and whether you already have a medical condition. While this all sounds scary, the push to develop a coronavirus vaccine is moving at high speed. Studies of other coronaviruses led most researchers to assume that people who have recovered from a sars-cov-2 infection could be protected from reinfection for a period of time. But that assumption needs to be backed by empirical evidence, and some studies suggest otherwise. There are several different approaches for a potential vaccine against the coronavirus.

The basic idea is that you would get a shot that contains faint versions of the virus. The vaccine would make your body to a version of the virus that is too weak to cause infection, but just strong enough to stimulate an immune response. Within a few weeks, cells in your body/immune system would make markers called antibodies, which would be specific for only the coronavirus or specifically its spike protein antibodies then attached to the virus and prevent it from attaching to your cells.

 Antibodies of Coronavirus

Your insusceptible framework at that point reacts to signals from the antibodies by expending and decimating the bunches of infections. On the off chance that you, at that point contract the genuine infection at a later stage, your body would remember it and obliterate it. At the end of the day, your resistant framework is presently prepared. Gathering proof on whether this will be conceivable, sheltered and successful is a piece of what's taking analysts such a long time to build up an antibody. It's a test of skill and endurance to build up an antibody. In the midst of a pandemic, each progression in antibody advancement, as a rule, takes months, if not years. 

An Ebola antibody broke records by being prepared in five years. The expectation here is to create one for the new coronavirus in a record-breaking 12 to year and a half. While the entirety of this will require some serious energy. Remain at home, on the off chance that you can, to secure the most powerless. What's more, remember to wash your hands for in any event 20 seconds and as regularly as could reasonably be expected.
