Swine flu is highly infectious! With greater awareness and proper diagnostic tests, many more cases are now being recorded. Prevention is simple if one maintains basic hygiene i.e. wash hands with soap and water, always sneeze into a napkin or handkerchief, avoid contact with infected people or articles and keep homes and work spaces well-ventilated. Consumption of water and liquids and fresh fruit (especially Vitamin C) is also recommended.
