Hi thank you for querry, As swine flu or H1N1 is a viral infection which is highly contagious and it spread through respiratory droplets to other persons. The person who are in close contact of the patient effected the more. Patients who develop flulike illness (ie, fever with either cough or sore throat) should be strongly encouraged to self-isolate in their home for 7 days after the onset of illness or at least 24 hours after symptoms have resolved. While in home isolation, patients and other household members should be given infection control instructions, including frequent hand washing with soap and water. Use alcohol-based hand gels. Patients with H1N1 influenza should wear a face mask when within 6 feet of others at home. Hope the information will help you to asses your condition and prevention of others. wish you a good health.
