How long does the Swine Flu live on surfaces like doorknobs, keyboards, and desks?
Influenza thrives in warm, moist environments, and dies on cold, dry surfaces. You should mostly be concerned with people within a 6 foot radius of you, who are coughing or sneezing openly. Do not shake their hands and then touch your face. Do not breathe deeply if someone has just coughed or sneezed anywhere near you. Doorknobs and other commonly touched surfaces are very inefficient ways to spread Influenza. That being said, you should not absently touch your face at any time. Try to make sure you wash your hands with anti-bacterial soap and/or use a hand sanitizer at regular intervals throughout the day.
