Disease transmission varies within three (3) primary types of transmission: droplet, airborne (aerosol), and yes ... contact surfaces.

"Covid spreads significantly through contaminated hands and surfaces in households, a new study suggests, as researchers warned too much focus has been given to airborne transmission" (1.).

"Infections with respiratory viruses are principally transmitted through three modes: contact, droplet, and airborne.
* "Contact transmission is infection spread through direct contact with an infectious person (e.g., touching during a handshake) or with an article or surface that has become contaminated. The latter is sometimes referred to as 'fomite transmission.'
* "Droplet transmission is infection spread through exposure to virus-containing respiratory droplets (i.e., larger and smaller droplets and particles) exhaled by an infectious person. Transmission is most likely to occur when someone is close to the infectious person, generally within about 6 feet.
* "Airborne transmission is infection spread through exposure to those virus-containing respiratory droplets comprised of smaller droplets and particles that can remain suspended in the air over long distances (usually greater than 6 feet) and time (typically hours)" (2.).
