Influenza (flu) is an infectious respiratory illness caused by influenza viruses. There are two primary types of influenza viruses: type A and B. Both Influenza viruses commonly spread during the flu season. Flu season is unpredictable, but is typically starts in October and ends May. Influenza occurrences are generally at their peak between December and February. Cases of influenza range from mild illnesses to life threatening.
Influenza spreads by coughing, sneezing, and airborne droplets. In some cases, one can even contract influenza by touching an object or surface infected with the flu virus, and then touching their mouth or nose. Symptoms of influenza include: fever, chills, coughing, sore throat, stuffy nose, muscle aches, headaches, fatigue, vomiting and diarrhea.
Every year the Central Disease Center makes a flu vaccine that targets certain strains of the flu virus that scientist believe will likely spread that year. Doctors recommend that the elderly, young children, and people with certain health conditions (pregnancy, asthma, heart disease, diabetes) always get vaccinated because they are …show more content…
Those who survived lived on to experience the even deadlier 1918 flu pandemic. The 1918 flu crisis raged throughout Europe and many who survived the infection later died from pneumonia. The 1918 flu pandemic resulted in approximately 20 to 50 million deaths worldwide, nearly 2.5% to 5% of the world’s population.
Influenza viruses pose significant impacts on social economy, global economy, and human population. The viruses have a large social impact with increased demands on health-care systems, increased disabilities and even death. The flu also impacts the economy by reducing productivity at work and increasing health-care costs. The flu even affects human population, as evidenced by the large number of deaths in
