Cold represents the viral infection of the nose and throat, as well as sinuses and upper airways. The cold can lead to nasal stuffiness, runny nose, sneezing, sore throat and cough. In most of the cases the common cold is treated by itself and it usually gets better without treatment. There are various viruses that can cause the common cold and people may get it again later in life. The common cold affects both children and adults, however adults have 2-4 instances of it per year, while children have 3-8. This is due to the child’s immune system being less developed which makes it more vulnerable to infections.
It has been proved that women are more likely to get a common cold than men and this may be due to the fact that they come into more and closer contact with children than men. Cold can be spread by various means, but the most common I the direct contact. This involves sneezing or cough during which the virus particles are spread in the air and can be inhaled by the surrounding people. Another means of spreading it is by indirect contact which involves snoozing on certain objects that another person will touch within a few minutes and then touch his/her nose of mouth.
Most commonly, the cold occurs in winter because during this time people tend to have a closer contact with each other while staying longer time indoors. Moreover, studies show that the cold weather is making people more likely to develop it. The duration of the cold in adults and older children is usually one week and the symptoms can be relieved with medication and drinking plenty of water to help the body fight the infection.
The causes of the common cold are the viruses, among which the mostly spread ones are the rhinoviruses and the coronaviruses. Considering that a various number of viruses can cause a cold, sometimes an individual can have one cold after another, due to the different viruses that cause it. Generally, the affected parts of the body in case of common cold are the lining of the nose and throat which brings to the inflammation of these areas. Due to this, these areas start to produce more mucus which leads to runny nose and sneezing frequently.
