Vuvuzelas - the horns used by football fans celebrating 2010's World Cup - not only cause noise pollution but may also spread diseases, say experts

A short burst on the instrument creates a spittle shower similar to a sneeze, traveling at four million droplets a second. In crowded venues one person blowing a vuvuzela could infect many others with airborne illness like the flu or TB. Critics say that they are anti-social and unsafe because of their potential to generate a din louder than a plane taking off.
