Abstract

Objective: To analyze the evidence on the relationship between air pollution and an increased risk of morbidity and mortality from Covid-19.

Materials and methods: An adaptation of the Cochrane rapid review methodology was used. The search was performed in PubMed and MedRxiv and was limited until April 28 and 26, respectively. The titles and abstracts were reviewed by five researchers who, in turn, reviewed the full texts of the final selection.

Results: 450 manuscripts were found, 15 met the inclusion criteria. The evidence reports that the incidence and risk of morbidity and mortality from Covid-19 increase with chronic and acute exposure to air pollution, particularly to particulate matter (PM2.5, P M10) and nitrogen dioxide.

Conclusions: More studies are required especially in Latin American cities. It is necessary to strengthen the recommendations in cities with higher levels of pollutants and to reduce their emissions.

Objetivo: Analizar la evidencia sobre la relación entre la contaminación del aire y un riesgo mayor de morbimor-talidad por Covid-19.

Material y métodos: Se utilizó una adaptación de la metodología de revisiones rápidas de Cochrane. La búsqueda se realizó en PubMed y MedRxiv y se limitó hasta el 28 y 26 de abril, respectivamente. Los títu-los y resúmenes fueron revisados por cinco investigadores que, a su vez, revisaron los textos completos de la selección final.

Resultados: Se encontraron 450 manuscritos, 15 cumplieron los criterios de inclusión. La evidencia encon-trada reporta que la incidencia y el riesgo de morbilidad y mortalidad por Covid-19 se incrementan con la exposición crónica y aguda a la contaminación del aire, particularmente a material particulado (PM2.5, P M10) y dióxido de nitrógeno.

Conclusiones: Se requieren más estudios especialmente en ciudades latinoamericanas. Es necesario fortalecer las recomendaciones en las ciudades con mayores niveles de contaminantes y reducir sus emisiones.
