Personal protective equipment during the COVID‐19 pandemic: a reply	2020-06-04		.txt	text/plain	396	21	53	For clarity, I neither stated that particles above 5 µm were large nor referred at all to whether these are visible or not and I am unclear why these are referred to in Professor Murphy's letter. However, the behaviour of particles is highly complex, not dependent only on size and much debated: as I stated in my article "the dichotomy into> 5 and < 5 µm particles leading to droplet or airborne spread, respectively, is likely to be simplistic, with aerosols being maintained over a wider range of particle size". I infer that Professor Murphy's concerns are that larger particles than described contribute to aerosols and therefore that airborne transmission is a significant risk, and that the 2 m 'droplet zone' is insufficient.
