Overweight people can spread the COVID-19 faster, specialists from the Massachusetts Institute of Technology and Harvard.

The study found that people with a high body mass index (BMI), as well as older patients, excrete the most respiratory droplets containing virus particles.

According to scientists, in different patients, the amount of exhaled aerosol particles can differ hundreds of times. So, according to the study, only 18% of people accounted for 80% of the exhaled bioaerosol, which proves the existence of the phenomenon of superproliferation.

According to experts, superproliferation is associated with damage to the mucous membranes during coronavirus, which is observed in the elderly and overweight people in a stronger form. The severity of the course of the disease also affects the rate of spread. If the lungs are severely affected, a person can become a super-spreader, even if they are not obese.
