Colds and Flu

The common cold and flu are types of upper respiratory tract infections that occur yearly, mainly during the fall and winter seasons.

Both conditions are caused by viruses and are associated with decreases immunological functioning. The causative agent in 30-50% of cases of the common cold is one of the many types of rhinovirus. Echovirus, coxsackievirus and other viruses, account for the remainder of reported cold and flu cases. The viruses that cause the flu are influenza viruses, which are members of the orthomyxovirus family.

Although the same viruses cause the highly publicized yearly flu outbreaks, these viruses are subject to changes in their genetic structure, also known as antigenic drift. Antigenic drift results in the creation of new vaccine every year. Occasionally, there are major changes in the genetic structure of the flu virus. This is known as antigenic shift. This mutation can result in flu pandemics that have major effects on the overall state of health around the world.
