According to Wikipedia, smallpox can be spreaded by direct contact with infected skin. Coughing, sneezing, speaking and even breathing can spread the virus through saliva droplets expelled from the mouth.
Liquid droplets in air are called mists, smaller droplets are aerosols. Solid particulates are dust, smaller sized ar fumes.

A suspension of liquid droplets or small (< 5µm) particles in the air. Aerosolized biological agents may remain suspended in air for long periods and may travel long distances. Aerosol transmission occurs when particles containing a biological agent are inhaled by another person. Aerosols are typically generated by coughing. However, aerosols can be weaponized in the case of an intentional attack with a biological weapon.
The particulate materials refers to the atmospheric aerosols that are originally applied to the solid particles but are at the moment extended to the droplets of the liquid.
1. Falling Temperatures 2. Water vapour in the air 3. Condensation nuclei-tiny particles of duct, soot, etc.
water droplets form when a cold surface touches a hotter surrounding air and condenses to form water droplets
Heat evaporates microscopic oil and/or water droplets. The droplets are carried around the home on tiny air currents (generated by central heating - or people walking around). The droplets enter your nostrils and your brain interprets what's been inhaled.
