Difference between a runner spitting versus just someone standing still

Explanation:

Runners while running do breathe, pant, and heave heavily which leads to spitting in the open as a habitual practice. This spitting while on motion leads to heavy dispersal of aerosol droplets which suspends in the air.

Droplets due to respiratory or spitting sources from any person who is infected with any infectious and contagious viral, bacterial, or other infectious diseases will have high chances of the pathogen present in them.

Further the rate and spread of droplet dispersal and transmission of pathogen will be higher compared to that from someone standing still. This puts greater potential for the spread of such droplet transmitted diseases.

Hence proper distancing should be maintained between runners and others to prevent spread of droplet transmitted diseases.
