why there is no medicine for common cold?¿?
Answers
Explanation:
The common cold, otherwise simply known as a cold, is a viral infection that attacks the upper respiratory tract.
This includes the nasal cavity, the pharynx (back of the mouth) and the larynx (voice box).
Rhinoviruses, coronaviruses, coxsackieviruses and adenoviruses are just some of the many different types of cold viruses.
These viruses stick to the cells of the adenoids at the back of your throat.
They quickly reproduce and rupture from the cells to spread to cells in the rest of the upper respiratory tract.

A vaccine to prevent the common cold has been difficult to make, primarily because there are more than 200 different varieties of viruses that can cause colds. SOURCES: National Institute of Allergy and Infectious Diseases: "Common Cold."
