Swine Flu (H1N1)

Swine flu, caused by the H1N1 virus, is a contagious respiratory illness that primarily affects pigs but can also infect humans. First identified in 2009, it spread globally, leading to a pandemic. Symptoms resemble those of seasonal flu, including fever, cough, sore throat, body aches, and fatigue. Most people recover without treatment, but it can be severe in vulnerable groups. Vaccines are available to prevent infection, and practicing good hygiene, like handwashing and respiratory etiquette, helps reduce transmission. Awareness and vaccination have significantly improved since the initial outbreak, making it less of a public health threat today.
