Like Kovid, the common cold is a viral infection. This infection is caused in the upper respiratory tract. The common cold is usually caused by 100 different human rhinovirus serotypes (the same number of species in one species and the type of surface protein virus). Coronaviruses, parainfluenza viruses, and adenoviruses are also common causes of the common cold.
That is why we often get colds and coughs, because when our body develops immunity against one type of virus, it comes in contact with another the next season. In some cases, like Covid, the viruses change and come out of the body’s immune system, re-infecting us.
Therefore, it is important to practice COVID precautionary measures to control the rate of common cold and cough.
