[Does nebulization present a risk of viral transmission? A narrative review].

Nebulization is a commonly applied therapy for patients with respiratory conditions, encompassing those infected with respiratory viruses such as SARS-CoV-2, influenza and RSV. Since the COVID-19 pandemic occurred, concerns have arisen regarding the release into the environment of airborne particles during nebulization.
