Droplets from sneezing,and coughing do fly through the air at tremendous velocity ( data states 3,000 microns at 39 miles per hour to 100 mph landing up to 30 feet ) on surfaces nearby . How long these droplets stay active depends on what they are composed of. Hepetitis last 16 hours on a solid surface sometimes up to 4 days! All the above data can be researched on Google or CDC site.
