Viruses that cause colds
There are many different types of viruses that cause colds and not only one virus. It is difficult for doctors to determine the cause of each case of cold because the symptoms are very similar to the degree of conformity. They can only be detected by laboratory tests, but these viruses are usually transmitted in the same way To the person, by direct contact, the virus can pass from the infected person to the hands or face of the other person as a result of peace or so and then to the eyes, nose or mouth, the cold virus can live on the skin of the injured for two hours of time.

How to get a cold
When the virus enters the nose of the nose, it enters the cells in the nose and begins to multiply there, and then the viruses generated from the cell and multiply in other cells very quickly, and then spread the virus in the bloodstream and in the airways and lungs, and when the proliferation of the virus inside the body and spread The role of the immune system in fighting this virus.
The immune system initially sends white blood cells to attack the virus, which the body considers strange. If you have been infected with this virus before, the body will be able to know it, and will store information about it and how to eliminate it, In the other case, the first attack of white blood cells will fail and reinforcements will be sent.
At the same time, the nose and throat will burn as a way to fight the virus, and the person will begin to feel tired and tired as a result of consuming a lot of energy in the body in the fight against the virus, and if the body can not quickly eliminate it will move slowly through the respiratory system and will move with him also to be the body of a vaccine for the virus .
Therefore, access to vaccines against viruses helps to significantly reduce the symptoms of the virus and the seriousness of infection because the vaccines contain viruses that are exhausted and dilute the concentration helps the body to form a vaccine against it easily and without exposure to disease, so the body can quickly eliminate when entering the body .
