Specific features of coronavirus super-distributors named

A new study by the University of Central Florida has highlighted physiological traits that could make humans super-proliferators of COVID-19.

Researchers at the UCF Department of Mechanical and Aerospace Engineering have used computer models to simulate sneezing in different types of people. They are distinguished by their physiological characteristics.

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 others around him increase. Accordingly, if a person does not have a stuffy nose and sneezes through it, then the distance the droplets of saliva move decreases.

According to the US Centers for Disease Control and Prevention, the main way people get infected with the virus that causes COVID-19 is through contact with respiratory droplets, such as sneezing and coughing, which carry 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.
