Why is the common cold virus difficult to care in humans?
It possesses a viral genome that mutates very quickly
It is caused by a special type of virus called a retrovirus
It attacks white blood cells that fight off foreign bodies
It is a spherical-shaped virus with many protein receptors
The correct answer is: It possesses a viral genome that mutates very quickly.
The common cold virus, or the rhinovirus, is difficult to cure in humans primarily because it possesses a viral genome that mutates rapidly. This high mutation rate makes it challenging to develop effective treatments or vaccines since the virus can quickly evolve and evade immune responses or develop resistance to antiviral drugs.
