Disease of the Week
Influenza (flu) is a common contagious viral respiratory illness that infects the nose, throat, and lungs. Flu viruses spread mainly by droplets made when people with flu cough, sneeze or talk. Flu illness can vary from mild to severe. When severe, flu can result in hospitalization and even death. Some people are more likely to suffer serious flu complications, including older adults, pregnant women, young children and people with certain chronic health conditions. CDC recommends that everyone 6 months and older get an annual flu vaccine. Flu vaccination can prevent flu illnesses and its potentially serious complications. While flu vaccination varies in how well it works, an annual flu vaccination is the best way to protect against flu. However, there is a second line of defense for treatment of flu. Influenza antiviral drugs are prescription medications that reduce severity and duration of illness and also may prevent serious flu complications. CDC recommends influenza antiviral treatment for people who are very sick with flu and people with flu symptoms who are at high risk of developing serious flu complications.
