People all over the world suffer from the infectious disease called common cold. This is considered as the most common of all diseases among humans and is very infectious.Humans are not often able to build immunity and resistance to different viruses that cause such an uncomfortable infection, and this is the main reason for it being the most common and most recurring disease.
As per the experts it is less risky to catch a cold when the weather is colder than when it’s warmer. Here are a few causes of the common cold.
Common Cold Causes In Humans
Common Cold Caused By Rhinoviruses
This virus contributes up to 80% of viruses that cause a common cold. This virus is most active in spring, summer and autumn. There are over one hundred and ten different viruses that have been found under this one single virus form.
It has been said that out of all viruses, this one does not cause very serious diseases and illnesses compared to others.Rhinovirus is usually present in cells and lines the nose and begins reproducing even further causing the common cold.
Coronaviruses That Cause A Cold
There is a difference between adult and child colds. Coronaviruses usually cater to cold that are caught by adults. This virus is mostly active during the spring season as well as the cold winter season.
There are almost thirty to forty different viruses under Coronaviruses, but only three or four of them all affect humans.This virus contributes up to 15% of viruses that cause a common cold. The body is unable to resist from such viruses and hence causes the common cold.
Transmission Of The Virus
Another cause of the common cold is due to the transferring of droplets or coming in contact with secretions that are already infected by the common cold.
Droplets known as aerosols are transmitted in many ways, like from hand to hand or hand to object or surface. Transmission in children who are going to school is much more common than in others.This infection can also be brought home by family members. However people who sit close to infected people tend to be at a higher risk of getting a common cold.
Weather, A Common Cause
It is very commonly said by most people that a cold can be caught due to subjecting oneself to the cold weather. However, people should be aware that a cold is not caused by the weather but by viruses.
The endurance of such weather and the immunity level usually cause a common cold. Cold or wet weather can also cause low immunity and illnesses leading to the common cold. Due to the change in our respiratory system, a cold can also be caused.
Stress, Infections And Allergies
There are major chances, and researchers also suggest that a common cold may not necessarily be caused by tonsil problems, exercise, or diet. Stress and diseases caused by allergies that cause problems for your nose and throat, have chances of getting infected by viruses that cause common cold.
Lack of sleep as well as malnutrition can cause the body to have a low resistance to viruses that cause cold. A common cold occurs when the above viruses manage to attack the human body and infect it. The first signs are the production of mucus.
This is generally produced in the nose and the throat and dust and dirt that enter the nose and throat are trapped by the mucus leading to more infection. So for those who are unaware of the causes of the common cold must ensure that they read the above points and are aware of the causes of this infectious disease.
