How do viruses affect our bodies?

 Firstly, you know how viruses work, it is necessary to think on a small scale. The viruses are too small we cannot see them with our eyes, in fact, viruses are tiny microbes on the planet, yet they can make a person sick and even kill.

Now, how can something so small make a person so sick? How does the virus reproduce inside the body until it infects another person? 

1. They are more common than you think.

• First, I tell you something about viruses, viruses are small pieces of RNA (ribonucleic acid) or DNA (deoxyribonucleic acid), surrounded by a protein coat. A virus cannot replicate alone; instead, it must infect cells and use components of the host cell to make copies of itself.

• Viruses have different shapes, such as rods, rounds with crowns, or cylindrical tails, which you cannot see with a simple microscope. To see viruses, you need an electron microscope, which uses electrons instead of light to produce an image.

• There are many types of viruses such as rabies, measles, smallpox, chickenpox, hepatitis, HIV, flu, coronavirus(covid-19), etc.

2. How do viruses enter the body?

• Usually, all the viruses enter the body through; the mouth, nose, eyes, genitals, or through wounds, and if you contact the infected person also one of the main reasons viruses enter the body.

• Some viruses enter the body in direct contact, there is also some indirect contact when a person touches an object (door, handlebar, table) that has a virus on it when an infected person sneezes, coughs, and talks when the mucous membrane comes into connecting another person. 

• In some cases, viruses enter the human body through, food, water, or blood and also through mosquitoes, rats, snakes, etc.

3. How do we fight viruses?

• A third mechanism used by antibodies to eradicate viruses is the activation of phagocytes. The virus-bond antibody binds to receptors, called Fc receptors, on the surface of phagocytic cells and triggers a mechanism known as phagocytosis by which the cell engulfs and destroys the virus.

• If an antigen enters the body and B-cells recognize it (either from having had the disease before or from being vaccinated against it). B-cells will produce antibodies. When antibodies attach to an antigen (think a lock-key configuration). It signals other parts of the immune system to attack and destroy the virus.

Make your immune system strong so viruses never attack your body.
