Introduction:

Several investigations have attempted to establish the impact of some meteorological and environmental parameters on the transmission of SARS-CoV-2, considering each country's geographical characteristics and seeking to mitigate the disease's advancement by controlling these factors.

Objective:

Analyze the evidence on the possible relationship between environmental factors, morbidity, and mortality due to SARS-CoV-2/COVID-19, both globally and within Colombia.

Methodology:

A comprehensive review of the scientific literature was carried out in the electronic databases. Additionally, the impact of some environmental variables and the severity of COVID-19 cases were analyzed during the period from April 8 to July 29, 2020, for the city of Bogotá.

Results:

The correlational analysis between the ICU admission rates in Bogotá and the environmental factors like temperature, PM2 5, O3, NO, NO2 y CO levels, and ozone concentration showed an inversely significant relationship. Meanwhile, there was a positive correlation between the levels of nitrogen oxides (NO/NO2) and carbon monoxide (CO). Some of these results could be related to the effects of the quarantine imposed by local governments.

Conclusion:

Globally, there is enough evidence to link environmental conditions and parameters with increased morbidity and mortality for COVID-19. Evidence at the national level is still scarce.
