Influenza, commonly known as the flu, is an acute respiratory infection caused by influenza viruses that circulate worldwide. Each year, it infects approximately 1 billion people across all regions, leading to 3-5 million cases of severe illness.
The consequences of influenza extend beyond discomfort and lost productivity. Respiratory complications from the flu are responsible for an estimated 290,000 to 650,000 deaths annually, highlighting the virus's significant impact on global health.
Prevention is key to mitigating the effects of influenza. Vaccination, good hygiene practices, and staying informed about outbreaks can help protect individuals and communities from this pervasive virus.
