Can I get COVID-19 from kissing?

Waleed Javaid, MD, Associate Professor of Medicine (Infectious Diseases) at the Icahn School of Medicine at Mount Sinai in New York City, says it is possible, but not likely.If someone in the house who is infected with the virus is coughing and sneezing and not being careful, then tiny virus particles in respiratory droplets could be circulated in the air. Anything that moves air currents around the room can spread these droplets, whether it is an air conditioning system, a window-mounted AC unit, a forced heating system, or even a fan, according to Dr. Javaid.
