Browsing: Influenza

Influenza, commonly known as the flu, is a highly contagious viral infection that affects the respiratory system, including the nose, throat, and lungs. It is caused by influenza viruses, primarily types A and B, which undergo frequent changes, leading to seasonal outbreaks and occasional pandemics. The flu spreads through respiratory droplets when an infected person coughs, sneezes, or talks. Symptoms of influenza include fever, chills, cough, sore throat, runny or stuffy nose, muscle or body aches, headaches, and fatigue. While most people recover within a few weeks, influenza can lead to severe complications, such as pneumonia, especially in young children, elderly individuals, pregnant women, and those with underlying health conditions. Vaccination is the most effective way to prevent influenza and its complications, with annual vaccines developed to match the most prevalent strains each season. Antiviral medications can also be used to treat the flu, particularly in high-risk populations. Public health measures, such as good hygiene practices, respiratory etiquette, and staying home when symptomatic, are crucial in controlling the spread of influenza.
