A national study of primates and humans with COVID published in the National Academy of Sciences makes a number of shocking discoveries, including data showing only a fifth of individuals are responsible for 80 percent of viral transmission.
The study tracked the expiration of virally loaded aerosols from humans and primates and Tulane National Primate Research Center Director of Infectious Disease Aerobiology Chad Roy said they discovered that much like other airborne infectious diseases such as tuberculosis COVID weakens airway mucus allowing viral particles to move more freely out of the body.
“The virus is physiologically rigging the respiratory system to produce these aerosols in greater numbers and it kind of gets to the underpinnings of transmission potential,” said Roy.
While the findings suggested that young and healthy people tend to generate far fewer droplets than the older and less healthy, the researchers cautioned that any individual, when infected with the coronavirus, may be at risk of producing a large number of respiratory droplets

What makes some one a COVID-19 super-spreader? By Kaitlin Rust | February 10, 2021 at 9:55 PM CST - Updated February 10 at 10:25 PM
NEW ORLEANS (WVUE) - Researchers at Tulane University have contributed to two significant COVID-19 super-spreader studies and have started to narrow down how the virus is transmitted.
“There’s not a lot of solid stuff around how this disease is transmitted,” Dr. Chad Roy said.
We know COVID is airborne, but after studying almost 200 people researchers from Tulane and several other universities suggest people who are older with a higher body mass index breathe out more respiratory droplets with the virus.
Obesity, age, and the state of COVID-19 infection influence the number of virus particles an infected person breathes out, according to a new study which says these factors determine if a person becomes a super-spreader of the virus.
