Concept explainers
To determine: The cause of frequent occurrence of common cold in humans.
Introduction: Common cold is a frequently occurring infection in humans which is caused by RNA viruses, called rhinoviruses, and other respiratory viruses. The virus binds the cellular adhesion molecules and invades the upper respiratory tract. The general symptoms of infection are nasal stiffness, sneezing, scratchy throat, and watery discharge from nose
To determine: The methods of the spread of cold viruses.
Introduction: Viruses lack cell division machinery, and are unable to replicate on their own. Hence, viruses infect the host and utilize its cell division machinery to make copies of its own. Viruses are highly infective and are responsible for causing a range of diseases in humans.
