[h=3]Excerpt[/h] Influenza is a communicable viral disease that affects the upper respiratory tract including upper and lower respiratory passages. It is caused by a wide spectrum of influenza viruses. Some of these viruses can infect humans, and some are specific to different species. These viruses are transmissible through respiratory droplets expelled from the mouth and respiratory system during coughing, talking, and sneezing. The influenza viruses can be transmitted by touching inanimate objects soiled with the virus and touching the nose or eye. Influenza can be transmitted before the patient is symptomatic and until 5 to 7 days after infection. After infection, it takes a few days for most of the healthy patients to recover fully, but complications that include pneumonia and death are common in certain high-risk groups. These groups include young children, elderly, immunocompromised, and pregnant females. Symptoms of influenza include a runny nose, high fever, cough, and sore throat. Influenza spreads rapidly and efficiently in seasonal epidemics. Flu epidemics occur every autumn and winter in temperate regions and affect a significant portion of adults and children, but seasons differently impact age groups and severity.
