Is it true that a sneeze can release up to 40,000 bacteria?

Yes, it is true that a sneeze can release up to 40,000 bacteria. Sneezing is caused by the contraction of muscles in the nasal cavity and mouth. The force of this action causes air to be pushed out through the nose and mouth at speeds of up to 200 miles per hour. This powerful burst creates an aerosol spray containing billions of tiny particles of mucus, saliva, and other bodily fluids. These airborne particles are then inhaled by nearby people or surfaces.
