The sneezing speed is shown for four different types of nose and mouth:
- A - open nasal passage with a closed mouth,
- B - open nasal passage with an open mouth,
- C - blocked nasal passage with an open mouth,
- D - blocked nasal passage with a closed mouth.
It turned out that if a person sneezes with his mouth open,then the chances of infecting those around him increase. Accordingly, if a person does not have a stuffy nose and he sneezes through it, then the distance the droplets of saliva move decreases.
According to the US Centers for Control and Preventiondiseases, the main way people get infected with the virus that causes COVID-19 is through contact with respiratory droplets, for example, from sneezing and coughing, carrying the infectious virus.
The researchers also modeled three types of saliva: liquid, medium, and thick. They found that liquid saliva shatters into small droplets that stay in the air longer than medium or thick ones.
