Answer: False
Step-by-step explanation:
Airborne pathogenic infection usually spread when viruses, bacteria or any other pathogenic agent travel over the dust particles or respiratory droplets.
The pathogens can travel to a great distance in air being on the tiny nano particles of dust particles and respiratory droplets. The pathogens of cough or sneeze travel a long distance very quickly. These pathogens travel upwards at a speed of 320 km/h. In indoors the speed of airborne pathogens increases and their potential to cause infection also increases.
