They include coughing, sore throat, runny nose, sneezing, headache, and fever . People usually recover in seven to ten days . Some symptoms may last up to three weeks .

They spread through the air during close contact with infected people and indirectly through contact with objects in the environment followed by transfer to the mouth or nose . Risk factors include going to daycare, not sleeping well, and psychological stress . Symptoms are mostly due to the body's immune response to the infection rather than to tissue destruction by the viruses themselves . People with influenza often show similar symptoms as people with a cold, though symptoms are usually more severe in the former . Influenza is less likely to result in a runny nose . </P>
