COVID-19

This is respiratory disease CoV-2.It belongs to the family of corona viruses, named for crown like spike son their surfaces. respiratory disease CoV-2 will cause COVID-19,a contagious infection that attacks primarily your throat and lungs. What really happens in your body after you contract the corona virus? What precisely causes your body to develop pneumonia? and the way would a vaccinum work? The corona virus should infect living cell sin order to breed. Let’s have a more in-depth look. within the virus, genetic material contains the data to create additional copies of itself. A macro molecule shell provides a tough protecting enclosure for the genetic material because the virus travels between the individuals it infects. Associate in Nursing outer envelope permits the virus to infect cells by merging with the cell’s outer membrane. sticking from the envelope area unit spikes of macro molecule molecules. each a typical respiratory illness virus and also the new corona virus use their spikes sort of a key to urge within a cell in your body, wherever it takes over its internal machinery, re purposing it to create the elements of recent viruses. once Associate in Nursing infected person talks, coughs or sneezes, droplets carrying the virus might land in your mouth or nose then 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 semi permeable membrane sort of a key during a lock. This action permits the virus to urge within your cell. A typical contagion virus would travel within a sack made up of your semi permeable membrane to your cell’s nucleus that wherever your cell homes all its genetic material. The corona virus, on the opposite hand, doesn’t got to enter the host cell organ. It will directly access components of the host cell, referred to as cell organ. cell organ use genetic data 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 together with your cell’s outer layer, the semi permeable membrane. All the components required to form a replacement virus gather simply to a lower place your cell’s membrane. Then a replacement virus begins to butt faraway from the cell’s membrane. 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 breathe in, each air sac inflates like a small balloon. And when you exhale, the sacs deflate. Small blood vessels, called capillaries, surround your alveoli. Oxygen from the air you breathe passes into your capillaries, 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 catch most germs in the mucus that lines 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 may 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 a corona virus infection, the virus can overwhelm your immune cells and your bronchioles and alveoli become inflamed 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 broncho pneumonia 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 difficult that you need a machine called a ventilator to help you breathe. These are the machines that save lives and medical device companies currently ramp up production for. Whether you would develop these symptoms depends on a lot of factors, such age and whether you already have an existing condition. While all this all sounds scary, the push to develop a corona virus vaccines moving at high speed. Studies of other corona viruses lead most researchers to assume that people who have recovered from a SARS-CoV-2 infection could be protected from re infection 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 corona virus. The basic idea is that you would get a shot that contains faint versions of the virus. The vaccine would expose your body to 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 immune system would make markers called antibodies, which would be specific for only the corona virus or specifically its spike protein. Antibodies then attach to the virus and prevent it from attaching to your cells. Your immune system then responds to signals from the anti bodies by consuming 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 corona virus 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.
