Facts About Common Cold- How You Can Protect Yourself and Others

The common cold is a viral infection that affects the upper respiratory tract primarily the nose, throat, sinuses, and larynx. The common cold is a self-limited contagious disease caused by a number of different types of viruses. In medical terms, a common cold is referred to as a viral upper respiratory tract infection. Over 200 virus strains contribute to causing the common cold in which the Rhinovirus plays an important part.

Cold can also be caused by viruses including coronavirus, respiratory syncytial virus, influenza, and parainfluenza. They spread through the air by close contact with infected people. The common cold is the most frequent infectious disease of humans. An average adult gets about two to three colds per year while that number increases to six to eight in children. These infections occur more commonly during the winters.

How Does A Common Cold Start

One can catch a common cold from another person infected with a cold-causing virus. It can be caught also by the virus released in droplets by coughing or sneezing. It basically starts when a virus finds a place for itself in the lining of your nose or throat. Our immune system then gives out white blood cells to attack the trespasser.  If our body has not come into contact with the same strain of virus before the initial attack can fail and then our body has to send in reinforcements. Now our nose and throat start to make a lot of mucus.

As almost all our body’s energy is directed at fighting the cold virus our body is left feeling tired and all down and out. One does not get a cold by coming into contact with water. The thing that helps to catch you cold is extreme tiredness, being under emotional distress, and have allergy problems.

These infections develop from September to November and from March to May. Other similar viruses are the Parainfluenza virus, Respiratory Syncytial virus, Adenovirus virus, Coronavirus.

A cold virus enters our body through our mouth, eyes, or nose. When some sick coughs, sneezes or talks should cover their face. This helps the prevention of the spread of droplets filled with germs. The body is unable to build resistance against all kinds of viruses because new viruses are constantly forming in our bodies. So colds are a frequent, never-ending problem to face. It occurs most frequently during fall, winter, and spring.
