Flu Symptoms

Influenza, commonly shortened to “flu,” is a respiratory illness caused by influenza A or B viruses. It is extremely contagious and usually spread by the coughs and sneezes of a person who is infected. It appears most frequently in winter and early spring which is the time for viruses to breed. The virus attacks the body by spreading through the upper and/or lower respiratory tract.

Symptoms of flu may be same as other viral infections or cold but it varies in intensity. A person attacked by flu may experience more intense symptoms than normal cold and may linger for about a week. The feeling of tiredness and gloom can continue for several weeks.
