Resumen en inglés

The coronavirus disease outbreak was first reported in Wuhan, China in late 2019 and early 2020. SARS-CoV-2 is a single-stranded RNA virus, the main cause of a serious respiratory disease called COVID-19, which is the cause of the current pandemic and which has spread rapidly in the human population. This review brings together the most relevant studies, carried out to date worldwide, which focus on knowing whether air pollution, especially particulate matter (PM2.5 and PM10), is considered a propitious transport agent for the virus, having taking into account that PM is identified as the main environmental cause of disease and premature death in the world, since it has a toxicity capacity that can increase by being able to absorb other substances such as polycyclic aromatic hydrocarbons (PAH), its heavy metals so that pathogens as long as they are below the radius of its diameter. Factor that affects the body's immunity, which makes people more vulnerable to contagions, therefore, it is important and crucial to elucidate the role of air pollution particles in the spread of the virus through a technique that is fast, accurate, versatile, easy to use and cost efficient like UV-visible spectroscopy. The method used to carry out this monograph was through a search, collection and bibliographic review of articles and scientific studies, graduate work, books, publications in scientific journals. Finding that there is a positive association between exposure to particulate matter and the presence of the virus. In addition, numerous studies highlight the potential links between exposure to air pollution and the severity of COVID-19, but there are very few investigative reports on the fast, accurate and economically viable diagnostic method such as UV-visible spectroscopy. Finally, according to the research carried out to date, they emphasize the importance of scientific studies to elucidate the role of air pollution particles in the spread of the virus and the performance of a technique for the sensitive and accurate detection of SARS-CoV viruses. -2 in the air.
