(author), Jimenez, J.L. (author)Some infectious diseases, including COVID-19, can undergo airborne transmission. This may happen at close proximity, but as time indoors increases, infections can occur in shared room air despite distancing. We propose two indicators of infection risk for this situation, that is, relative risk parameter (Hr) and risk parameter (H). They combine...journal article 2022

(author), Kurnitski, Jarek (author), Li, Yuguo (author), Miller, Shelly (author), Sekhar, Chandra (author), Morawska, Lidia (author)The coronavirus disease 2019 (COVID-19) pandemic has caused untold disruption throughout the world. Understanding the mechanisms for transmission of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is key to preventing further spread, but there is confusion over the meaning of ‘airborne’ whenever transmission is discussed....review 2021

Kurnitski, Jarek (author), Kiil, Martin (author), Wargocki, Pawel (author), Boerstra, A.C. (author), Seppänen, Olli (author), Olesen, Bjarne (author), Morawska, Lidia (author)A new design method is proposed to calculate outdoor air ventilation rates to control respiratory infection risk in indoor spaces. We propose to use this method in future ventilation standards to complement existing ventilation criteria based on the perceived air quality and pollutant removal. The proposed method makes it possible to...journal article 2021
