Quick Answer
HAND SANITIZER CANNOT ELIMINATE AIRBORNE PATHOGENS, as it is designed to kill germs on surfaces and on people's hands, not in the air.
Understanding Airborne Transmission
Airborne pathogens are tiny particles that can be inhaled, causing infection. They are usually spread through coughing, sneezing, or talking. Since hand sanitizer is not a gas or aerosol, it cannot come into contact with airborne pathogens in the air.
The Mechanism of Hand Sanitizer
Hand sanitizer typically contains between 60% to 95% ethanol or isopropanol. These liquids are effective against a wide range of bacteria and viruses, but they require a surface to act on. When applied to the skin, they denature proteins and disrupt cell membranes, ultimately killing microorganisms. However, once airborne pathogens are in the air, they are not in contact with a surface, so hand sanitizer cannot affect them.
Precautions Against Airborne Transmission
To prevent airborne transmission, follow these steps: avoid close proximity to infected people, wear a mask or respirator that filters out virus-sized particles, and ensure good ventilation in the area. Regularly clean and disinfect surfaces with a suitable product, and wash your hands frequently with soap and water. If you’re in a high-risk situation, consider using a face shield or other protective gear to prevent exposure.
