abstract = "Knowledge of respiratory bacteria/virus concentration and distribution on a surface is critical for assessing contact transmission. Here, we investigate the direct bioaerosol deposition and distribution on a near surface from a cough experimentally. A cough generator is used to release bacterium/virus-laden droplets. A solid surface is put in front of the cough generator. Escherichia coli (E-coli) and bacteriophage are used to represent the respiratory bacteria and virus, respectively. Results show that the number concentration of deposited droplets and viable bacteria/viruses on the surface decrease from the impingement point to surface edge. We identify the region of the impingement area on the surface in which the microorganism fraction accounts for around 83% of the overall deposited bacteria/phage along a vertical line. The E. coli-laden droplets have similar distribution with that of the phage-laden droplets, meaning that the microorganisms inside the droplets do not affect the droplet deposition onto near surfaces.",
