H1N1 Influenza

H1N1 Influenza, commonly known as swine flu, is a respiratory illness caused by the H1N1 virus, which is a subtype of the influenza A virus. First identified in 2009, it spread quickly worldwide. Symptoms are similar to those of regular flu, including fever, cough, body aches, and fatigue. While most cases are mild, some can lead to severe illness, especially in young children, the elderly, or those with weakened immune systems. Vaccines are available and effective in preventing H1N1, and public health measures, like hygiene and vaccination, help control its spread.
