COVID-19 primarily attacks the respiratory system and spreads easily through the droplets produced by coughing or sneezing. The moist respiratory aerosol contains active viral particles that remain in the air for up to three hours after leaving the nose, sinuses, mouth, throat, and lungs. You can easily breathe in the infected aerosols and contract the COVID-19 virus.
10. Can Talking Spread COVID-19?
New research released by the Proceedings of the National Academy of Sciences of the United States of America shows that the simple act of talking is enough to rapidly spread the virus from person to person. So how dangerous is talking? If a person is sick with COVID-19 or asymptomatic, talking to the individual puts you at significant risk of contracting the virus via airborne spread. COVID-19 is a novel virus, so humans have no known immunity and will easily become infected. Symptoms usually develop in three to 14 days.
9. How Speaking Spreads COVID-19
Talking in a loud voice sends forth thousands of fluid droplets that contain large quantities of active virus. The droplets remain in stagnant air for up to 14 minutes, and when aerosolized they stay in the air for up to three hours. Clearly, talking causes the virus to become airborne when confined in certain environments, and a prolonged conversation puts you at extreme risk of contracting the virus.
