The most frequently occurring illness in children and adults throughout the world and a leading cause of doctor visits, missed days from school and work is the common cold.
The common cold is medically referred to as a viral upper respiratory tract infection caused by a virus. The viruses that cause colds are spread by infected airborne droplets or by direct contact with infected secretions.
Even though colds are more common in the winter months, the weather itself does not increase the chance of getting a cold. People are in closer contact with each other at this time of year, because they stay indoors making it more likely to infect each other.
