EnglishInfluenza (Flu)
According to the WHO, the average global burden of seasonal influenza is on the order of 600 million cases, with 3 million cases of severe illness and 250,000-500,000 deaths per year.
Influenza, or flu, is a respiratory infection caused by viruses. Seasonal flu outbreaks usually begin suddenly and occur mainly in the late fall and winter. Most people who get it recover within a week or so, but for elderly people, newborn babies, and people with certain chronic illnesses, the flu and its complications can be life-threatening. The CDC estimates that in the United States more than 200,000 people are hospitalized and about 36,000 people die from the flu and its complications every year.
