AdvantagesAdvantages • Easily withdrawn of drug • Easy and convenient to apply. • Faster Onset of action. At the time the study was published, the scientific consensus was "that most transmission via respiratory secretions happens in the form of large respiratory droplets rather than small The virus that causes COVID-19 can persist in aerosol form, some studies suggest. But the potential for transmission depends on many factors, including infectiousness, dose and ventilation to include non-aerosol forms of sulfuric acid in threshold and release determinations.

We call them aerosols of anthropogenic origin. Hardly anyplace in the world is free of anthropogenic aerosols, and we inhale them continuously. But aerosols also originate in nature: fog, sand, forest exudates, and sea spray are just a few examples. Aerosols are minute particles suspended in the atmosphere; they affect Earth's radiation budget and climate Aerosols are particles that are suspended in the air. When humans breathe, talk, sing, cough or sneeze, the emitted respiratory droplets mix in the surrounding air and form an aerosol.
