Influenza, commonly known as the flu, is an infectious disease of birds and mammals caused by an RNA virus of the family Orthomyxoviridae (the influenza viruses). In humans, common symptoms of influenza infection are fever, nausea, vomiting, sore throat, muscle pains, severe headache, coughing, and weakness and fatigue. In more serious cases, influenza causespneumonia, which can be fatal, particularly in young children and the elderly. Sometimes confused with the common cold, influenza is a much more severe disease and is caused by a different type of virus. Similarly, the unrelated gastroenteritis is sometimes called "stomach flu" or "24-hour flu".

Colds typically last three to five days, with residual coughing lasting up to three weeks. It is the most common of all human diseases, infecting adults at an average rate of 2?4 infections per year, and school-aged children as many as 12 times per year. Infection rates greater than three infections per year per person are not uncommon in some populations. Children and their parents or caretakers are at a higher risk, possibly due to the high population density of schools and the fact that transmission to family members is highly efficient. ...
