Preventing Swine Flu Vaccination and Hygiene Strategies

Isabella Harper

Swine flu, also known as H1N1 influenza, is a contagious respiratory illness caused by a strain of the influenza a virus. This virus is called "swine flu" because it was initially believed to have originated in pigs, although it can also spread from human to human. Swine flu gained significant attention and concern during a global outbreak in 2009, which was declared a pandemic by the World Health Organization (WHO). Since then, swine flu has continued to circulate as a seasonal influenza virus alongside other common flu strains. Swine flu is characterized by symptoms similar to those of regular seasonal flu, including fever, cough, sore throat, body aches, fatigue, and sometimes gastrointestinal symptoms like nausea and diarrhea.
