Treatments for influenza include a range of medications and therapies that are used in response to disease influenza. Treatments may either directly target the influenza virus itself; or instead they may just offer relief to symptoms of the disease, while the body's own immune system works to recover from infection.

Children are much more infectious than adults and shed virus from just before they develop symptoms until two weeks after infection. [1] [2] The transmission of influenza can be modeled mathematically, which helps predict how the virus will spread in a population. [3] Influenza can be spread in three main ways: [4] [5]
In 1977, H1N1 reemerged in humans, possibly after it was released from a freezer in a laboratory accident, and caused a pseudo-pandemic. [34] [77] This H1N1 strain was antigenically similar to the H1N1 strains that circulated prior to 1957. Since 1977, both H1N1 and H3N2 have circulated in humans as part of seasonal influenza. [1]
Pandemrix was found to be associated with narcolepsy from observational studies, increasing the risk of narcolepsy by 5-14 times in children and 2-7 times in adults. The increased risk of narcolepsy due to vaccination in children and adolescents was around 1 incident per 18,400 doses. [ 6 ]
Children infected in the 2009 H1N1 flu pandemic were no more likely to be hospitalized with complications or get pneumonia than those who catch seasonal strains. About 1.5% of children with the H1N1 swine flu strain were hospitalized within 30 days, compared with 3.7% of those sick with a seasonal strain of H1N1 and 3.1% with an H3N2 virus. [198]
“In adults over the age of 65, symptoms almost always include a cough, whereas with the flu, coughing is usually just present in about two-thirds of patients,” he says.
Influenza-like illness (ILI), also known as flu-like syndrome or flu-like symptoms, is a medical diagnosis of possible influenza or other illness causing a set of common symptoms. These include fever, shivering , chills , malaise , dry cough , loss of appetite , body aches, nausea , and sneezing typically in connection with a sudden onset of ...
The virus is a novel strain of the influenza virus, [2] for which existing vaccines against seasonal flu provided no protection. A study at the U.S. Centers for Disease Control and Prevention (CDC) published in May 2009 found that children had no preexisting immunity to the new strain but that adults, particularly those over 60, had some degree of immunity.
