“…Yao et al (10) evaluaron las concentraciones de PM2.5 y PM10 en forma diaria, con la mortalidad por COVID-19, resultando que a mayores concentraciones de estos contaminantes, existe mayor tasa de mortalidad, lo que concuerda con lo publicado por Mehmood et al (51) donde aparentemente la exposición de las poblaciones a PM2.5 contribuyen a corto y largo plazo a una mayor incidencia de letalidad. En cambio, la exposición a corto plazo a una concentración elevada de SO2, se relaciona con una clara disminución de infección a COVID-19 (9) .…”

“…Por otro lado, la mayoría de las investigaciones se centran en áreas metropolitanas, por tanto, es de importancia evaluar la contaminación del aire en ciudades pequeñas, realizando comparaciones en relación al tamaño de áreas urbanas (66) ; a la vez, explicar la baja reducción de PM10 en comparación con NO2 y el carbono negro (12) , así como monitoreo y especiación de los hidrocarburos no metánicos (HCNM) debido a que los niveles de ozono se relacionan con el aumento entre los HCNM /NOx (67) . De igual manera, se requiere futuras investigaciones para entender mejor las fuentes de emisión y química atmosférica (68) , por lo tanto estudios en laboratorio son imprescindibles, donde se exploren los mecanismos subyacentes de la exposición a concentraciones de contaminantes como PM2.5, PM10, CO, NO2 y O3, los cuales se asocian a un mayor riesgo de infección por el COVID-19 (9,51) . Finalmente, se debe incluir una evaluación del impacto de la contaminación del aire en relación a aspectos epidemiológicos y mortalidad por COVID-19 en base a densidad poblacional, segregación racial y nivel socioeconómico (69,70) .…”

La pandemia COVID-19 genera preocupación en todo el mundo, desde que el 30 de enero se declaró como emergencia de salud mundial (WHO), lo cual trajo consigo el cambio en el estilo de vida de la población, cierre de sistemas de transporte, paralización de actividades económicas, reduciendo las emisiones de contaminantes al ambiente, causando la mejora de la calidad del aire en muchas ciudades a nivel mundial. Hasta el momento, se han publicado varios estudios de revisión enfocados en los impactos ambientales por COVID-19, sin embargo, ninguno se enfoca específicamente en la contaminación del aire. Por lo cual, el objetivo principal fue presentar una revisión basada en un análisis integral de los estudios publicados abordando implicancias teóricas usadas dentro de los estudios. Se analizaron 68 estudios, los cuales se publicaron en 17 revistas hasta agosto del 2020. Además, se abordan posibles futuras investigaciones en relación al tema. Finalmente se exponen las conclusiones de la presente revisión.

“…However, the former is more worrying because their small size allows them to penetrate deeper into the human respiratory system via inhalation, which can potentially promote respiratory diseases (Chai et al, 2019;Dominici et al, 2006;Horne et al, 2018) such as COVID-19. Thus, it is of note that citizens exposed to a high concentration of PM2.5 are more prone to developing chronic respiratory diseases favorable to infective agents (Mehmood et al, 2020). Long-term exposure to these small particles can produce a chronic inflammatory stimulus, especially in unhealthy people (Conticini et al, 2020).In addition, short-term exposure to PM2.5 particles may also increase susceptibility to infections (Chen et al, 2020).…”

“…Long-term exposure to these small particles can produce a chronic inflammatory stimulus, especially in unhealthy people (Conticini et al, 2020).In addition, short-term exposure to PM2.5 particles may also increase susceptibility to infections (Chen et al, 2020). Indeed, this type of pollution can harm human airways, promoting viral infections, and diminish the immune response (Liu et al, 2019;Mehmood et al, 2020;Sedlmaier et al, 2009). The World Health Organization's air quality guidelines recommend that PM2.5 concentration should not exceed a 10 μg/m 3 annual mean and 25 μg/m 3 24-hour mean(World Health Organization, 2018).…”

The COVID-19 outbreak has escalated into the worse pandemic of the present century. The rapid spread of the new SARS-CoV-2 coronavirus has caused devastating health and economic crises all over the world, with Spain being one of the worst affected countries in terms of confirmed COVID-19 cases and deaths per inhabitant. In this situation, the Spanish Government declared the lockdown of the country with the aim of flattening the epidemic curve. The variations of air pollution in terms of fine particulate matter (PM2.5) levels in 8 cities of Spain are analyzed here considering the effect of meteorology during the COVID-19 lockdown period (from March 15th to April 12th 2020). The results of the analysis show that the 4-week Spanish lockdown was not long enough to reduce the PM2.5 levels in all the cities considered. These reductions were less than those expected, despite the drastically reduced human activity. Furthermore, no associations between COVID-19 accumulated cases and PM2.5 exposure or environmental conditions (temperature, precipitation, wind speed, sunlight hours, maximum pressure) were found during the early spread of the pandemic.

“…Another study that establishes the relationship of higher COVID-19 mortality and morbidity to PM 2.5 in northern Italy provides a piece of sharp evidence that persons living in an area with high levels of PM 2 . 5 are more susceptible to developing respiratory diseases, which facilitate the impact of any infectious agent, especially in children and unhealthy population (Mehmood et al, 2020;Conticini et al, 2020).…”
