Pneumonia is one of the most common complications that can occur as a result of the flu. The condition can become very serious and even life-threatening. Each year, pneumonia causes over a million hospitalizations and more 50,000 deaths in the United States.
From 1404 to the middle of the 19th century, 31 flu epidemics were recorded, including eight large-scale pandemics, which killed millions of people and highlighted a need for international cooperation on public health. Cooperation began with the first International Sanitary Conference, held in 1851.
While many of us get sick during flu season, it is frequently avoidable. In fact, during the 2016-2017 flu season, flu vaccination prevented an estimated 5.3 million influenza illnesses, 2.6 million flu-associated medical visits and 85,000 flu-associated hospitalizations.
