Abstract. In queste ultime settimane, sono stati diffusi online contributi sotto forma pre-print (senza peer-review) che discutono o presentano analisi di dati sulla relazione tra i livelli di inquinamento atmosferico e l’epidemia di COVID-19 (malattia del Coronavirus causata dalla SARS-CoV-2). L’attenzione è posta in particolare sui potenziali effetti del particolato fine (PM), sulla diffusione della epidemia e sulla prognosi delle infezioni respiratorie.

Abstract. Scientific studies show evidence of a correlation between air pollution levels and respiratory diseases, with a possible increase in the morbidity of respiratory viral infections. However, following the outbreak of Covid-19, the possible effects of the PM (particulate matter) concentrations on the susceptability and pollution-mediated effects are not scientifically demonstrated yet.
In order to shed light on this topic, we performed a narrative review of the scientific literature upon the potential effects of PM on spreading, pathophysiology and prognosis of viral respiratory infections related to Covid-19.
We discuss four hypotheses: 1) how can air pollutants affect the prognosis of respiratory infectious diseases; 2) how can the interaction between air pollutants and pathogens increase the infectious potential of respiratory pathogens; 3) how can air pollutants foster the infectious potential of respiratory pathogens by veiculating them; 4) how can air pollutants worsen the respiratory co-infections by increasing antibiotic resistance.
