claim: chronic aerosol increases with covid-19 infection, and risk factors of disease symptom severity
evidence_1: in our observational cohort study of the exhaled breath particles of 74 healthy human subjects, and in our experimental infection study of eight nonhuman primates infected by aerosol with sars- cov-2, we found that exhaled aerosol particles increase one to three orders of magnitude with aging, high bmi, and covid-19 infection.", "we studied respiratory droplet generation and exhalation in human and nonhuman primate subjects with and without covid-19 infection to explore whether sars- cov-2 infection, and other changes in physiological state, translates into observable evolution of numbers and sizes of exhaled respiratory droplets in healthy and diseased subjects."
