Biological fluid dynamics of airborne COVID-19 infection
2020
Rendiconti Lincei SCIENZE FISICHE E NATURALI
Preserved Fulltext
The relevance of the subject stems from the key role of airborne virus transmission by viral particles released by an infected person via coughing, sneezing, speaking or simply breathing. ...
We review the state of knowledge on the bio-fluid dynamic mechanisms involved in the transmission of the infection from SARS-CoV-2. ...
The authors wish to thank Andrea Prosperetti and Mogens Høgh Jensen for thorough and insightful remarks on an earlier version of the manuscript. Thanks are also due to Giorgio Parisi, Pietro Cappuc- ...
