How does coronavirus affect the body

Coronavirus: Well, part of the family that causes the coronavirus is the SARS CoV-2. The SARS CoV-2 it belongs to the family of coronaviruses. However, they are named from their crown-like spikes on the surfaces.

Meanwhile, the SARS CoV-2 can cause COVID-19 which is a contagious viral infection that attacks primarily the lungs and throat. Now, the question is, WHAT HAPPENS IN YOUR BODY WHEN YOU CONTRACT THE CORONAVIRUS? WHAT EXACTLY CAUSES YOUR BODY TO DEVELOP PNEUMONIA? And HOW WOULD A VACCINE WORK? HOW CAN YOU PREVENT CONTRACTING THE CORONAVIRUS? Well, let’s take a look at the answers to these questions.

Before we move in-depth, I will love to say this. In this very article, some biological terms were used to gain explanation and I know some persons might not be familiar with some of the used terms here, but bear with us. Just understand the process, that’s the key. So, let’s continue.

Meanwhile, viruses are living like-organism and for the Coronavirus to exist, it must infect living cells in other to reproduces. Inside the virus, genetic material contains the information to make more copies of it. Also, it will require a protein shell to provide a hard protective enclosure for the genetic material because the virus travels between the people it infects.

Moreover, an outer envelope allows the virus to infect cells by merging with the cell’s outer membrane, projecting from the envelope are spikes of protein molecules. Meanwhile, both a typical influenza virus and the new coronavirus uses their spikes like a key to get inside a cell in the body. There inside the body, where it takes over its internal machinery, repurposing it to build the components of new viruses.


Meanwhile, this virus moves with droplets and when an infected person talks, coughs or sneezes. Droplets carrying the virus may land in your mouth or nose and then move into your lungs. Therefore, when this happens and the virus is inside a person’s body, the virus comes into contact with cells in your throat, nose or lungs.

One spike of the virus, insert into a receptor molecule on your healthy cell membrane like a key in a lock. Well, this action allows the virus to get inside your body cell.

Thereafter, the virus travels inside a sack made from your cell membrane to your cell’s nucleus because that’s where your cell houses all its genetic materials. Then the viral envelope and cell membrane sack combine, allowing the viral genetic material to leave the sack and enter the nucleus.

Meanwhile, the viral genetic material hijacks the energy and materials in your cell’s nucleus to make thousands of copies of it. Although, some of the genetic material moves out of the nucleus, then attaches to the protein building parts of your cell called ribosomes. These then use information from the genetic material to make other viral proteins, such as the spike protein. A packaging structure in your cell then carries the spikes in vesicles, which merge with your cell’s outer layer, the cell membrane.

All the parts needed to create a new virus gather just beneath your cell’s membrane. Thereafter, a new virus begins to butt off from the cell’s membrane. Now, with the virus spreading in your body, how can you develop Pneumonia Symptoms?



Well, for this, we’ll look into the lungs. Moreover, each lung has separate sections, called Lobes. Normally, as you breathe air movies freely through your trachea or windpipe. Then through large tubes called bronchi through smaller tubes, called bronchioles, and finally into the tiny sacs, called alveoli. Your airways and alveoli located through your lungs are flexible and springy.

When you breathe in, each air sac inflates like a small balloon and when you exhale (breaths out), the sacs deflate. Small blood vessels, called capillaries, surround your alveoli. Meanwhile, oxygen from the air you breathe 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.

Meanwhile, 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 make expel them by coughing.

Normally, cells of your immune system attack viruses and germs that make it pass 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 in breathing
  • Chest pain
  • Coughing
  • Fever and Chills
  • Confusion
  • Headache
  • Muscle Pain and Fatigue


Well, 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. Meanwhile, these are the machines that save lives and medical device companies currently ramp up production for.

Whether you will develop these symptoms depends on a lot of factors, such as your age and whether you already have an existing condition. While all this all sounds scary, the push to develop a coronavirus vaccine is moving at high speed.

However, studies of other coronaviruses lead 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.

Well, there are several different approaches for a potential vaccine against the coronavirus. Moreover, the basic idea is that you would get a shot that contains faint versions of the virus. The vaccine would expose 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 immune system would make markers called antibodies, which would be specific for only the coronavirus 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 antibodies by consuming and destroying the clumps of viruses. If you then catch the real virus at the 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. Hence, it’s 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.


  • If you have a runny nose and spectrum, you have a common cold because coronavirus pneumonia is a dry cough with no runny nose.
  • Well, coronavirus is not heat-resistance and will be killed by a temperature of just 26-27 degrees.
  • Meanwhile, if someone sneezes with it, it will take about 10 feet (3.048metre) before it drops to the ground and is no longer airborne.
  • This virus can stay on surfaces. If it drops on a metal surface, it can last up to at least 12 hours before dying off. So, if you come into contact with any of these metal surfaces, ensure to wash your hands as soon as you can with a bacterial soap.
  • While on fabric, it can survive for 6-12 hours. Normal laundry detergent will kill it. For this very reason, it’s expected that you wash your hands frequently with running water, as the virus can only live on your hands for 5-10 minutes. Although, a lot can happen during that time like you can rub your eyes, pick your nose unwittingly and so on.
  • Also, drinking warm water is effective for all viruses. For this reason, everyone should ensure that their mouth and throat are moist and never dry.  So, try not to drink liquids with ice, but ensure to at least take a few sips of water every 15 minutes. This is because, even if the virus gets into your mouth, water or other liquids will wash them down to your stomach and once there, the acid in your stomach will kill the entire virus.
  • If you don’t drink enough water more regularly, the virus can then find their way to your windpipe and then into your lungs.
  • Well, you should also gargle as prevention. However, a simple solution of salt in warm water will suffice and you should drink plenty of water!

The Symptoms:

Firstly, it will affect the throat, so you will have a sore throat lasting for 3/4 days. Then, the virus then blends into a nasal fluid that enters the lungs, resulting in pneumonia. Well, before the, it would have gone through the trachea. This further takes about five (5) to six (6) days.

Secondly, with pneumonia comes high fever and difficulty in breathing. However, the nasal congestion is not like the normal kind, you feel like you’re drowning. Most importantly, at this point, it’s expected you seek immediate attention.

However, the new coronavirus may not show signs of infection for many days. But how can one know if he/she has been affected by the virus? By the time they have a fever and/or cough and go to the hospital, the lung is usually 50 percent (%) Fibrosis and it’s too late.

Therefore, experts in this field of study provide a simple self-check that everyone can do every morning they wake-up. They advise that when you wake up in the morning, you should take a deep breath, and then hold your breath for more than 10-11 seconds.

Well, if you complete that successfully without, stiffness, tightness, discomfort and without coughing. It proves that the lung is not fibrosis, basically indicates that there is no infection in the lungs.

Ensure to clean every surface at your home or workplace with detergent and do use an Alcohol-based hand sanitizer just in case you aren’t close to running water.

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
