Common Cold; its Causes, Symtoms and prevention

The common cold is an upper respiratory tract infection caused by many different viruses. However, the most common virus causing it is known as the rhinovirus and It multiplies best at temperatures found in the nose.
The common cold is transmitted by virus-infected airborne droplets or by direct contact with infected secretions.
Being in cold weather does not cause the common cold, but cold weather promotes close contact.
It is also a self-limited disease that can be managed at home and most people with a common cold recovered in about 7 to 10 days.
How the common cold spreads
It is spread either by direct contact with infected secretions from contaminated surfaces or by inhaling the airborne virus after individuals sneeze or cough.
It can also be caused by person to person transmission. Such as when an individual touches their nose and then touches someone or something else.
A healthy individual who then makes direct contact with these secretions can subsequently become infected, often after their contaminated hands contact their own eyes, nose, or mouth.
This virus can also live on frequently touched objects such as doorknobs, pens, books, cell phones, computer and keyboards. It lasts for several hours and can thus be acquired from contact with these objects.
The most important prevention measure for the common cold is to avoid contact with infected individuals.
